Diabetic Retinopathy
A diabetes-related eye disease that damages the retina — if untreated, it can lead to severe vision loss or blindness.
What is Diabetic Retinopathy?
Damage to the tiny blood vessels of the retina caused by long-standing or uncontrolled diabetes.
Diabetic Retinopathy is an eye condition where high blood sugar levels damage the blood vessels of the retina — the light-sensitive layer at the back of the eye that sends images to the brain via the optic nerve.
In diabetic patients, prolonged uncontrolled sugar levels cause these vessels to leak fluid, proteins, and fats, or become blocked. If left untreated, Diabetic Retinopathy can lead to severe visual loss or complete blindness. Samyak and NetraJyoti Eyecare Centre offers advanced treatment for this condition.
How Does Diabetic Retinopathy Progress?
Retinopathy typically starts with mild leakage and progresses through different stages:
- Non-Proliferative Diabetic Retinopathy (NPDR): Early stage. Blood vessels leak fluid or blood, get clogged or rupture. Vision may still be normal or only mildly affected.
- Proliferative Diabetic Retinopathy (PDR): Advanced stage. Due to poor blood flow, the retina grows abnormal new blood vessels (neovascularization). These fragile vessels can bleed inside the eye (vitreous haemorrhage), cause tractional retinal detachment or neovascular glaucoma, leading to severe visual loss or blindness.
Some patients also develop Diabetic Maculopathy, where fluid rich in fats and cholesterol leaks near the macula (central retina), affecting central vision.
Symptoms of Diabetic Retinopathy
In the early stages, Diabetic Retinopathy has no noticeable symptoms. This is the best stage to treat it, before vision is affected. When symptoms appear, damage is often advanced.
Possible symptoms at later stages may include:
- Blurred or fluctuating vision
- Dark spots or patches in the field of vision
- Difficulty reading or seeing fine details
- Sudden loss of vision due to bleeding in the eye
Because it can be silent initially, regular eye check-ups are essential for all diabetic patients.
Eye Complications Due to Diabetic Retinopathy
Diabetic Retinopathy can lead to several serious eye problems:
- Diabetic Macular Oedema (DME): Fluid leaks from damaged vessels near the macula, causing blurred central vision.
- Neovascular Glaucoma: New abnormal blood vessels grow on the iris and drainage angle, blocking fluid outflow and increasing eye pressure.
- Retinal Detachment: Scar tissue pulls the retina away from the back of the eye, causing severe vision loss.
How is Diabetic Retinopathy Diagnosed?
A dilated eye examination is essential to detect Retinopathy. Samyak and NetraJyoti Eyecare Centre is equipped with advanced diagnostic tools for comprehensive retinal evaluation.
Patients with Diabetic Retinopathy are usually advised to undergo eye examinations every 2–4 months, depending on the severity.
Treatment of Diabetic Retinopathy
Strict control of blood sugar, blood pressure and cholesterol is crucial to prevent or delay Retinopathy. However, Retinopathy may progress even with good control, especially in long-term diabetes.
Based on the stage and severity, the eye specialist may recommend:
-
LASER Photocoagulation Treatment:
A proven treatment for many forms of Diabetic Retinopathy. Although already lost vision cannot be restored, LASER can prevent further damage and reduce the risk of blindness. The LASER energy is absorbed by the retina and converted to heat, sealing leaking points and destroying abnormal new vessels. It is a safe, painless, day-care procedure. -
Vitrectomy Eye Surgery:
Recommended in cases with significant bleeding (vitreous haemorrhage) or scarring in the retina. The surgeon removes blood-filled vitreous and scar tissue and replaces it with a clear solution, thereby improving or stabilising vision. -
Intravitreal Injections:
In some patients with Diabetic Maculopathy, injections are given into the eye to reduce swelling, control leakage and improve central vision.
Recovery After Vitrectomy Surgery
Recovery after Vitrectomy usually takes about 2–4 weeks. During this period, patients may experience:
- Redness and swelling in the operated eye
- Mild to moderate pain
- Blurred vision while healing
Post-surgery, the ophthalmologist will advise you to:
- Wear an eye patch, usually for about a day
- Use prescribed eye drops to reduce swelling and prevent infection
- Avoid driving, heavy lifting and strenuous exercise for a few weeks
- Rest and follow posture instructions if a gas or air bubble is used inside the eye
In some cases, silicone oil may be injected into the eye and removed later with a second surgery.
Can Diabetic Retinopathy Be Prevented?
Diabetic Retinopathy may not always be fully preventable, but the risk of severe vision loss can be greatly reduced by:
- Maintaining good blood sugar control (as advised by your diabetologist)
- Controlling blood pressure and cholesterol
- Undergoing regular eye check-ups, even if vision seems normal
- Seeking prompt treatment if any visual changes occur
Early diagnosis and timely treatment help preserve vision and quality of life for people living with diabetes.
