Know Your Risk Of Developing Diabetic Retinopathy

Diabetic retinopathy is a condition that affects the eyes. This condition occurs in people suffering from type1 and type 2 diabetes. In this condition, the blood vessels in the retina get damaged.  The retina senses the light and sends images to the brain, helping the eyes to see. However, if not timely treated, diabetic retinopathy can lead to vision loss. Those with uncontrolled diabetes are at high risk of developing diabetic retinopathy. 


 In the beginning, you might not experience any symptoms or only mild vision issues. With time you may experience symptoms such as:

  • Dark floaters in the vision
  • Blurred and fluctuating vision
  • Dark areas in the vision
  • Vision loss during advanced stages

Risk factors: 

Diabetic retinopathy can occur in any person suffering from diabetes. Other risk factors that may lead to this condition are: 

  • High blood pressure
  • High cholesterol
  • Tobacco use
  • Pregnant women with gestational diabetes 


You can’t completely prevent diabetic retinopathy. But visual loss from diabetic retinopathy is preventable and can be treated. Medical management of diabetes, early detection of the condition, and timely treatment can reduce the risk of visual loss.

If  you have diabetes, reduce the risk of developing diabetic retinopathy by doing the following:

  • Make a healthy diet part of your daily routine.
  • Attempt to get something like 150 minutes of light to moderate, exercise such as walking, yoga, or aerobics every week.
  • Take diabetes medicines as prescribed.
  • Screen your glucose level regularly. You may have to check and record your glucose level a few times each day.
  • Quit smoking. Smoking increases the risk of diabetes-related complications, including diabetic retinopathy.

Taking an active role in diabetes management can go a long way toward preventing eye complications. If you have diabetes or you know someone who is suffering from diabetes, it is important to get regular eye exams.

Can Diabetic Retinopathy be cured? And other questions to ask your eye specialist

If you suffer from diabetes,  you should get your eyes tested for diabetic retinopathy annually. Diabetic retinopathy is one of the leading causes of vision loss. The longer you have diabetes and the less controlled the blood sugar levels are, the more likely you are to develop this eye condition. Seeing an eye specialist can help you clear your doubts regarding the eye condition. One of the most asked questions about the eye condition is —- can diabetic retinopathy be cured? Well, the answer is no. There is no cure for diabetic retinopathy. However, early detection of the disease can help in slowing down the progression of the disease or delay or reduce vision loss.

diabetic retinopathy

Here are a few questions you can ask your eye doctor regarding diabetic retinopathy:


  • What are the symptoms of diabetic retinopathy?

The symptoms of diabetic retinopathy are:

  • Blurred or fluctuating vision 
  • Impaired colour vision
  • Seeing spots 
  • Vision loss

Fact: Do you know what is the underlying cause of diabetic retinopathy? It is high blood sugar levels and high blood pressure. Keeping the two under control can prevent the eye condition from worsening. 

  • What are the different types of diabetic retinopathy?

Diabetic retinopathy can primarily be classified into:

  • Nonproliferative: It refers to the early stage of DR, where the retinal blood vessels break and leak.
  • Proliferative: In this type of diabetic retinopathy, new blood vessels grow in the retina abnormally, which can cause retinal detachment or scarring. This can further result in vision loss.


  • What are the complications that diabetic retinopathy can cause?

Diabetic retinopathy can cause eye conditions such as:  

  • Diabetic macular edema: Due to the leaking of retinal blood vessels, the fluid gets accumulated in the macular part of the retina. This causes blurry vision.
  • Neovascular glaucoma: The growth of abnormal blood vessels due to DR blocks the fluid from draining out of the eye. This causes a neovascular glaucoma, which can further result in vision loss.
  • Tractional retinal detachment: DR can lead to formation of scars in the back of the eye. This condition is called the tractional retinal detachment.
  • What are the risk factors for diabetic retinopathy?

There are few factors that can increase the risk of diabetic retinopathy:

  • Poor control of blood sugar levels
  • High level of hemoglobin A1C 
  • Having diabetes for a long period of time
  • High blood pressure level
  • High cholesterol 
  • Tobacco use

Fact: The prevalence of diabetic retinopathy in Indian urban diabetic population is around 18%.

Can Diabetic Retinopathy Resolve?


One of the many questions that our eye doctors in Kolkata are asked about diabetic retinopathy is whether or not the eye condition will resolve on its own. Although there is no cure for diabetic retinopathy, the right treatment can delay or reduce vision loss. Diabetic retinopathy is characterised by bulging blood vessels in the retina that happens as a result of diabetes. Bulging blood vessels often leak fluid or bleed – which can cause blurred vision, seeing eye floaters and difficulty seeing colours. 

Can diabetic retinopathy resolve?

At Disha Eye Hospitals, we have some of the best eye doctors in Kolkata who have shared with you a few important insights on the treatment of diabetic retinopathy: 


  • When is treatment needed? Treatment is required when the condition reaches an advanced stage and there’s a risk to the vision. When the condition has affected the macula of the retina or when peripheral vision has been severely affected, seeking medical treatment becomes important. 
  • What are the treatment options available? An eye doctor will determine the best treatment option that suits an individual. Those with advanced diabetic retinopathy will need surgical treatment to prevent vision loss. Remember, people suffering from diabetic retinopathy may need treatment more than once as the condition may get worse. 
  • Laser treatment: When the retina is severely damaged, laser treatment may be recommended. Using a laser, an eye surgeon will shrink the abnormal blood vessels, slowing the leakage of blood and fluid in the eye. Aggressive laser therapy may be used to treat severe proliferative retinopathy. This will prevent the growth of new blood vessels. However, laser treatment may not always work in treating proliferative retinopathy.
  • Vitrectomy: In case, the retina has not been severely damaged, then a vitrectomy may be recommended. This surgery is done when there is internal bleeding or retinal detachment. This surgery is also done to treat macular edema.
  • Medicines: An eye doctor may recommend anti-inflammatory medicines to slow the growth of abnormal blood vessels in the retina. In advanced stages of diabetic retinopathy, injections or steroids may also be given to shrink new blood vessels. 
  • How is diabetic retinopathy diagnosed? As diabetic retinopathy shows no early symptoms, it is essential that you get your eyes checked regularly. During a comprehensive eye examination, your eye doctor will put a few drops in your eyes to dilate the pupils. Then using a special lens, he/she will see the inside of your eyes including the condition of the  blood vessels. 
  • Is controlling diabetes important? The most important part of your treatment plan is to keep your sugar levels under check. In the early stages of diabetic retinopathy, controlling diabetes can help prevent vision problems from developing. In more advanced stages, controlling diabetes can help symptoms from worsening and this may prevent vision loss. If you have been diagnosed with diabetic retinopathy, it is important to keep diabetes under control.

Ocular Melanoma: 10 Important Things to Know

Cancer can develop in any part of the body, including the eyes. Among several types of eye cancers, Ocular Melanoma is one of the most serious ones. Ocular Melanoma occurs when cancer develops in the melanin, the cells that produce pigment in the iris.

Here are a few of the important things to know about Ocular Melanoma:

1) Ocular Melanoma is common in adults

Your risk of Ocular Melanoma increases as you age. If you fall under the age group of 50 and above, it’s important to visit an eye doctor every year. Our team of eye specialists at Disha Eye Hospitals, one of the top eye hospitals in Kolkata, use advanced medical tools and technology for precise diagnosis and treatment. Book an appointment online at

Also, another important reason to visit an eye doctor every year is Ocular Melanoma causes little or no symptoms during the early stages, and, therefore, usually goes undetected until it worsens.

Ocular melanoma 10 important things to know

2) Look out for a dark spot in the eyes

As Ocular Melanoma develops and starts progressing, it can cause a dark spot to develop in the iris or the conjunctiva, the front white part of the eyes. If the development of a dark spot is accompanied by a change in the shape of the pupils, it could be an indication of eye cancer. Make sure not to neglect the symptoms and instead consult with an eye doctor.

3) Prolonged exposure to sunlight increases Ocular Melanoma risk

While you may enjoy basking in the sun, you are putting yourself at the risk of Ocular Melanoma. This is because prolonged exposure to UV (ultraviolet) rays increases the risk of eye cancer.  Take proper safety precaution by wearing a pair of sunglasses when spending time outdoors. Choose a pair of sunglasses that has UVA and UVB protection.

4) A major risk factor of Glaucoma

As Ocular Melanoma progresses, it can increase the risk of a vision-threatening eye complication called Glaucoma. The eye complication occurs when the pressure inside the eye (intraocular pressure) increases.

If the progression of Ocular Melanoma leads to the onset of Glaucoma, you may experience several symptoms such as persisting eye pain, blurriness in vision, and seeing halos around the light.

5) Ocular Melanoma can spread to other parts of the body

One of the main reasons why Ocular Melanoma is a highly serious eye complication is the fact that the eye cancer can spread to other parts of the body, including the skin, bones, lungs, and liver. When any type of cancer spreads to other parts of the body, the process is called metastasis.

6) Dysplastic Nevus Syndrome increases your Ocular Melanoma risk

If you have Dysplastic Nevus Syndrome, you stand at an increased risk of Ocular Melanoma. Dysplastic Nevus Syndrome is an inherited skin disorder that causes abnormal moles. The skin disorder also increases the risk of Melanoma of the skin.

7) Radiation is one of the most common treatment options

Although Ocular Melanoma is a serious form of eye cancer, it can be successfully treated.  Radiation is one of the commonly-preferred treatment options; it involves deteriorating the cancerous tumour by exposing it to radioactive particles. This treatment can take 4 to 5 days.

8) Laser treatment is another effective option

Another way to successfully treat Ocular Melanoma is by using laser treatment.  Eye specialists choose this treatment option if the cancerous tumour in your eye is small. The treatment involves using a precisely-targeted infrared light to kill the tumour. Eye doctor adjusts the intensity of the infrared light in such a way that it can kill the cancer cells without causing damage to other parts of the affected eye.

9) Exercise regularly to reduce your risk of Ocular Melanoma

Physical inactivity is one of the general risk factors of cancer. Exercising regularly is a good way to reduce your risk of Ocular Melanoma. Depending on your age, you may choose low to moderate-intensity exercises such as jogging, running, swimming, and brisk walking.

If you are suffering from another health complication, make sure to consult with your eye doctor and plan your exercise regime accordingly.

10) Maintain a healthy and balanced diet

Although eating regime and Ocular Melanoma may not have a direct correlation, keeping your eyes healthy by eating a nutritious diet is a good way to reduce your risk of eye cancer.

Common Eye Injuries at Home, Prevention, And Treatment

From a general perspective, a home is fairly a safe place. But this is not entirely true when it comes to eye injuries as you stand at an equal risk of injuring your eyes as when you’re spending time outdoors.

Eye injuries are medical emergencies and need to be addressed with proper medical care. If you have suffered a physical eye injury, it’s crucial to visit an eye doctor as promptly as you can. To get the right treatment for your eyes, visit Disha Eye Hospitals, a well-known eye hospital in West Bengal. Book an appointment online at

Common Eye Injuries at Home, Prevention, And Treatment

Here are a few of the common types of physical eye injuries that occur at home:

1) Eye trauma:-

Trauma is one of the common types of household-related eye injuries.  It is also one of the most serious types of physical eye injuries. Falls are a common reason for eye trauma at homes. Improperly arranged rugs, carpets, tangled up electrical cords, and slippery floors are a few of the common causes of falls.

Physical activity and dexterity toys such as guns, powerful ball shooters, frisbees, and juggling clubs account for a significant number of eye injury cases.

2) Cuts:

Common household objects may seem safe, but with improper use, they increase the risk of serious cuts on the eyes. It’s important to use these common household objects with precaution to avoid eye injuries: knives, scissors, stationery, toys with sharp edges, multi-function tools, nail cutters, keys, and bottle openers.

3) Chemical burns:-  

Chemical burns are a serious form of eye injuries. You stand at the risk of chemical burns in the eyes when using  certain chemical solutions such as cleaning liquids, pesticides, and detergents when doing household chores.

To ensure proper safety, make sure to keep these chemical solutions away from the eyes. Also, when using such chemical solutions, avoid working too quickly as doing so increases the risk of spills and splatters.

Preventing eye injuries at home

Eye injuries are preventable accidents. At home, taking certain precautions goes a long way in minimising the risk of accidental eye injuries. Here are a few of the necessary precautions to take:

1) Wear safety eyeglasses:-

Taking eye safety precautions as simple as wearing a pair of protective eyeglasses helps you significantly reduce the risk of accidental eye injuries. Make it a rule in your home for everybody to wear protective eyeglasses when playing outdoor sports, doing gardening work, and spending time in the garage/workshop.

2) Install handrails on staircases

Staircases are undoubtedly one of the biggest risk areas for falls in your home.  One simple way to improve safety in staircases is to install sturdy and non-slipping handrails. Wooden handrails are a good option as they allow a firm grip. Also, make sure to install proper lighting in staircases to reduce the risk of falls.

3) Keep your power and hand tools in good condition

Damaged/faulty power and hand tools not only slow you down in completing your chores but can also cause eye injuries. Make sure to keep all your utility tools in good condition. In case you have faulty tools, either repair them or replace them with new ones.

4) Get rid of toys that have jagged edges

Although toys are your kids’ best companion, they can cause serious eye injuries. Avoid buying toys that have sharp edges. It helps to be mindful about buying toys for your kids as per the age manufacturers’ recommendations.

Eye injury treatment

There are certain do’s and don’ts to follow after you’ve met an accidental eye injury. Follow these safety and treatment tips to properly address different types of eye injuries:

1) Avoid rubbing the eyes

Whether you have suffered a chemical burn, a trauma, or a cut to the eyes, make sure not to rub the eyes, even if you have the urge to. In the case of chemical burns, rubbing the eyes can cause the chemical to go deep into the eyes. Rubbing the eyes can also make cuts and trauma worse.

2) Rinse with water

If you have suffered a chemical burn in your eyes, rinse the affected eye with water to flush the chemical out. Rinsing with water is a good option if a small foreign particle gets stuck in your eyes.

Seek medical help if you’ve suffered from an eye injury

An eye doctor is the best person to address the right treatment for your eye injury. Make sure not to avoid eye injuries as they can lead to complications such as vision blurriness and eye infection.

Diabetic Retinopathy: Important Pointers for the Patients

Diabetic Retinopathy: Important pointers for the patients

If you have Diabetes, you are at the risk of developing Diabetic Retinopathy, a serious eye disease which can cause permanent vision loss if not treated. However, with good control of blood sugar levels, blood lipids, and blood pressure, you can lower the risk of the eye disease.

This article will help you understand the eye disease more and learn about ways how you can reduce the risk as well as identify it and seek proper treatment.

What is Diabetic Retinopathy?

Diabetic Retinopathy is one of the complications of Diabetes that affects the eye. It occurs when high blood sugar levels damage the blood vessels in the retina. Due to the damage, the blood vessels swell and leak. The diabetic eye disease can cause vision loss and eventually lead to complete blindness.

There are two stages of Diabetic Retinopathy:-

  • NDPR (Non-proliferative Diabetic Retinopathy)

    NDPR is the initial stage of Diabetic Retinopathy. It involves leaking and swelling of the blood vessels in the retina, which if not controlled can lead to loss of vision.

  • PDR (Proliferative Diabetic Retinopathy)

PDR is the advanced stage of Diabetic Retinopathy. This stage involves the growth of new blood vessels which can bleed into the vitreous and either cause you to see floaters or dim/block your peripheral and central vision.

Identifying Diabetic Retinopathy

If you have Diabetes, an annual eye exam is a must for an early diagnosis. The following symptoms can indicate the occurrence of the eye disease:

  • Blurred vision
  • Dim vision
  • Vision loss
  • Impaired colour vision
  • Dark spots/floaters in your vision
  • Fluctuating vision

Diagnosing Diabetic Retinopathy:-

As discussed above, getting an annual eye exam helps in early detection which, in turn, can help you treat the eye disease and prevent it from progressing. When you visit an ophthalmologist, he/she will ask you about your medical history and determine your vision through an eye chart test. The doctor will use an ophthalmoscope to examine your retina.

Managing Diabetes to manage Diabetic Retinopathy:-

Effective management of Diabetes is essential to lower the risk/manage Diabetic Retinopathy. For Type 1 Diabetes, it’s important to follow an insulin routine tailored to your need and an appropriate diet.

For Type 2 Diabetes, being physically active, maintaining a healthy body weight, following a balanced diet, and leading an overall healthy lifestyle are the proper management measures.

You can also join support groups/communities to learn more ways of managing your Diabetes to lower the risk of complications.

Eye health maintenance tips:-

These tips can help you maintain your eye health and lower the risk of Diabetes-related vision complication:

  • Keep your blood sugar levels in control:- Have an A1c blood test conducted several times a year to keep track of your blood sugar levels.
  • Quit smoking:-Smoking can worsen your blood sugar. It’s a must to quit smoking if you have Diabetes.
  • Check your cholesterol levels:- High LDL is linked to blood vessel damage. Make sure to get your blood tested for finding how much LDL and HDL cholesterol you have.
  • Check your blood pressure:- Make sure check your blood pressure every time you visit your doctor as part of your Diabetes management plan.

Diabetic Retinopathy Guide

Diabetic Retinopathy, as the word implies, is a medical condition which causes progressive damage to the retina; mainly to the patients who have diabetes. When left untreated, the severity of Diabetic Retinopathy can eventually lead to blindness.

Diabetic patients have sugar (glucose) imbalance in their body as the metabolic disease interferes with insulin production. Later stages of diabetes cause damage to major organs of the body and eye is one of the first organs to get affected.

Analysts predict that the number of Americans affected by Diabetic Retinopathy is going to double up over the course of time. Hispanic Americans getting affected by this case are expected to reach up to 5.3 million by 2050.


Much like Macular Edema, self-diagnosis of Diabetic Retinopathy is very rare as you never know the onset of this eye complication. In most cases, patients are left clueless until severity and significant damages start to occur. Some of the common symptoms of Diabetic Retinopathy include:

  • Loss of central vision – You can diagnose Diabetic Retinopathy if you start losing sight or suffer poor vision while doing activities like reading and driving.
  • Colour Blindness – It is very common for a person to suffer from colour blindness when Diabetic Retinopathy prevails.
  • Night Blindness – If you start developing the inability to see during night-time, you might as well consider it to be the first effects of Diabetic Retinopathy.
  • Black Spots & Holes – One of the most dreadful initial effects of Diabetic Retinopathy is developing black structures that interfere with vision. To see it from the sufferer’s perspective, it would look something like –

diabetic vision


Diabetic Retinopathy is classified into 2 stages; NPDR (Non-proliferative Diabetic Retinopathy) and PDR (Proliferative Diabetic Retinopathy).

  • Stage 1 (NPDR)

During the early stages of Diabetic Retinopathy, the effects are indeed mild. In the 1st stage, blood vessels in the retina start to weaken and bulge out from their walls. This effect is also known as microaneurysm. These weakened blood vessels then release fluid into the retina which causes the macula to swell. NPDR is barely noticeable and doctors use fundus photography to confirm the onset of stage 1.

non-proliferative diabetic retinopathy

With time, the discharged fluid can fill up the macular region which leads to distorted vision which is not the same in both eyes. During NPDR, 10% of patients stand a high chance of developing vision loss.

  • Stage 2 (PDR)

When Diabetic Retinopathy enters stage 2, the disease gets more advanced. The early-on changes in PDR include growing of fragile blood vessels in the retina and vitreous. This phenomenon is also called neovascularization.

diabetic retinopathy

Then there are micro-disruptions in these fragile blood vessels which cause them to leak blood at the back of the eye which eventually interferes with vision. The retina eventually detaches due to the formation of scar tissue and development of glaucoma. This episode is followed by an extreme pain in the eye which eventually leads to blindness.


Although Diabetic Retinopathy usually occurs in patients who are already suffering from diabetes, other factors also contribute to the risk of developing this disease. Such factors include:

  • Pregnancy – As pregnant women are prone to develop gestational diabetics, therefore there’s a high chance that diabetes might cause Diabetic Retinopathy.
  • Race – Although researchers haven’t come up with specific reasons as to why certain groups of races get affected by Diabetic Retinopathy the most, White, African and Hispanic Americans hold the highest rate of the severity of this medical condition.
  • Other Medical Conditions –Apart from diabetes, other medical conditions such as high cholesterol and high blood pressure also trigger the risk of Diabetic Retinopathy.


Doctors usually diagnose Diabetic Retinopathy through a comprehensive eye examination. To diagnose the retina and macula, doctors go through a rigorous set of evaluations including:

-Patient History

Before starting with all the diagnosis, doctors generally go through the patient’s medical history to determine the cause of vision difficulties. In this step, the doctor determines whether it’s actually diabetes or other medical condition that is hampering eye health.

-Measurement of Visual acuity

Doctors also perform measurement of visual acuity to determine the loss of central vision. In case of minor central vision loss, the doctor might even prescribe eyeglasses for refraction of the eye lenses.

-Retinal Photography

To get a clearer picture of the status of retina, doctors conduct retinal photography for severely affected patients.

-Evaluating Ocular Structures

Further diagnosis of Diabetic Retinopathy involves the doctor evaluating the retina by dilating the pupil. The doctor might even conduct measurements for eye pressure to determine the severity of Diabetic Retinopathy.


Fundoscopic imaging and analyses

Fundoscopic imaging is one of the most favoured tools (diagnostics) by doctors to sort out Diabetic Retinopathy. Doctors take images of the retina to figure out abnormalities that are triggered by Diabetic Retinopathy. Doctors also use colour fundus photography to stage Diabetic Retinopathy.

To develop the further treatment plan, doctors access Fluorescein Angiography to take note of the abnormal growth of blood vessels. Now, computer-aided diagnosis has taken a massive leap of progress which involves the analysis of fundoscopic images to be automated. This computer automated diagnosis has several benefits including accuracy and time efficiency.

Blood Pressure Control

Controlling blood pressure is one rare measure that doctors take to cater prevention of Diabetic Retinopathy. According to a Cochrane study, controlling or reducing blood pressure has helped prevent Diabetic Retinopathy up to 5 years for patients who already have diabetes.

However, there is no evidence of blood pressure control slowing down the progression of Diabetic Retinopathy or preservation of the clarity of the vision.

Stem Cell Therapy

Stem cell therapy for Diabetic Retinopathy is under clinical trials as of now. According to the analogy of clinical trials, doctors can use the patient’s bone marrow to derive stem cells and inject them into the degenerated areas for regenerating the vascular system.

For further information, read


As C-peptide (aka Connecting Peptide) has shown promising results in treating vascular degeneration, Cebix (read organised a program of $50 million to complete the Phase llb trail in 2014. The trial showed no difference between placebo and C-peptide which caused the company to shut down the program entirely.

Light Treatment

In 2016, Noctura ( developed a medical device which the patients can use as a sleeping mask to treat Diabetic Retinopathy. As per the clinical trials, the mask emits green light on the eyelids which supposedly stops the retina’s rod cells to adapt dark light. This, in turn, reduces oxygen requirement which has a counter effect on the formation of blood vessels.


As of now, there are 3 major treatments for Diabetic Retinopathy which aid in restoring vision. Having said that, there’s no single solution for the complete cure of Diabetic Retinopathy till date.

Monitoring the symptoms vigilantly and getting optimal glycemic control is the best way to prevent the onset and delay further development of Diabetic Retinopathy. Here are the 3 main treatments:

1. Laser Photocoagulation

For treating Diabetic Retinopathy, doctors adapt Laser Photocoagulation into two usages. First, Laser Photocoagulation can be used to control neovascularization via panretinal coagulation and secondly for treating macular edema.

  • Panretinal Photocoagulation

Panretinal Photocoagulation aka scatter laser treatment is designed for treating PDR (Proliferative Diabetic Retinopathy). The process involves reducing the oxygen demand in the retina by creating 1,600 to 2,000 burns.

Before the ophthalmologist begins with the procedure, the physician numbs the eye by anaesthetic drops and dilates the pupil. The doctor may choose between pattern scan laser or a single spot laser.

From the patient’s perspective, you will see flashes of light during the procedure. This is accompanied by a stinging-like sensation. After the laser surgery, vision remains blurry for the rest of the day and the patients might suffer from a mild headache later on. Given the effectiveness of Panretinal Photocoagulation, this laser surgery involves several side effects too including reduced night and colour vision.

  • Laser Photocoagulation for macular edema

To treat macular edema with Laser Photocoagulation, doctors create a modified grid; a C-shaped pattern at the posterior pole with low-intensity burns. Clearing macular edemas helps in reducing the risk of vision. Read

2. Vitrectomy

Apart from laser surgery, Vitrectomy surgery is another treatment that doctors prefer; especially in the case where the vitreous contains lots of blood. To restore vision with vitrectomy, surgeons remove the blurry vitreous and replace it with a saline solution.

Vitrectomy doesn’t require special numbness and can be done under local anaesthesia. The surgery involved the doctoring making a tiny incision in the white portion of the eye to remove the vitreous. The doctor uses the same incision as a gateway to insert the saline solution.

The after-effects of the surgery include redness in the eye and sensitivity. In usual cases, patients are required to wear an eye patch for a couple of days. The doctor also prescribes medicated eye drop for prevention of infection.

3. Medication

Intravitreal anti-VEGF

Multiple doses of anti-VEGF intravitreal injection combined with Modified Grid Laser Photocoagulation works well for treating diabetic macular edema.

Intravitreal triamcinolone acetonide

Steroid preparation including Triamcinolone has lasting benefits in treating macular edema. The steroid is injected in the vitreous cavity which reduces the swelling of the retina that results in increased visual acuity.

In most patients, the effects of this steroid last for a time period of 3 months. This, in turn, necessitates repetition of the dosage to maintain the consistency of benefits.


Management and prevention of the onset of Diabetic Retinopathy (especially Proliferative Diabetic Retinopathy) entirely depends upon the management of diabetes. However, the patients can take several measures to prevent PDR. Some of these measures include:

  • Cholesterol and Blood Pressure Control

Diabetics with abnormal lipid metabolism and high blood pressure are vulnerable to get affected by Diabetic Retinopathy. As these factors can trigger the development of vascular changes at an alarming rate, Doctors recommend diabetics to maintain a normal BP and manage serum lipid levels by undergoing regulated medications.

  • Blood Sugar Control

It is always best to maintain a healthy lifestyle by doing physical activity on a regular basis and maintaining a healthy diet. Diabetics are often advised to consult a diabetic specialist for undergoing the best-suited hypoglycemic medications.

  • Quitting Tobacco

Smoking leads to abnormal blood sugar levels which create the risk of developing atherosclerosis. Similarly, hazardous habits like alcohol consumption and illicit drug abuse are a strict no for diabetics to prevent Diabetic Retinopathy.

  • Eye Examination

It is often recommended that a diabetic should visit a specialist for ensuring the working of hypoglycemic medication. Visiting an eye specialist every once in a while in 3 months is helpful to come up with diagnostics of vascular changes.

Alternatives to medication

As discussed earlier, there’s no definite cure to Diabetes or Diabetic Retinopathy. However, there are several herbal supplements which have seemed to work well for patients in the past. Some of these supplements that help in delaying the onset of Diabetic Retinopathy include:

  • Butcher’s broom

Butcher’s broom

  • Pycnogenol (Pine bark)

Pine bark

  • Bilberry


  • Grape Seed Extract

Grape Seed Extract

  • Gingko Biloba

As the percentage of diabetics suffering from Diabetic Retinopathy is increasing, several communities encourage patients to share up for creating a positive perception. Also, such communities provide information and make the patients aware of the available treatment options. Some of these communities include:

Macular Society:
Diabetes Research & Wellness Foundation:
