Retina

The most common conditions affecting the retina are:

  • Diabetic Retinopathy
  • Age-Related Macular Degeneration (ARMD/AMD)
  • RETINAL DETACHMENT
  • Flashes, Floaters & PVD ( posterior vitreous detachment)
  • Lattice Degeneration
  • Retinal Vein Occlusions (CRVO/BRVO)
  • High Myopia (Minus Power)

DIABETIC RETINOPATHY

Diabetes is a metabolic disease in which a person has high blood sugar. It is an epidemic with a global estimation of 285 million people being affected by diabetes in 2010. 93 million people have been reported to have diabetic retinopathy, with 17 million having proliferative disease and 21 million having diabetic macular edema worldwide.

WHAT IS DIABETIC RETINOPATHY?

As the name suggests, it is the damage in one’s eye (retina) due to diabetes. This can eventually lead to blindness. It affects up to 80% of all patients who have had diabetes for 10 years or more. Research indicates that 90% of these cases could be managed well with vigilant monitoring and early and appropriate treatment. The longer a person has diabetes, the higher his or her chances of developing diabetic retinopathy. The blindness induced by diabetes becomes irreversible if not treated on time. Beyond a particular stage, vision can never be restored. Hence it is important to catch the diabetic changes in the treatable stage, which is possible only by regular check-ups

WHEN DOES DIABETIC RETINOPATHY NEED TREATMENT?

There are different entities related to diabetic retinopathy- non proliferative (NPDR)/ proliferative (PDR) retinopathy and diabetic macular edema Patient usually needs treatment when they develop PDR or Macular edema.

FEW MYTHS RELATED TO DIABETIC RETINOPATHY

1. If Diabetes is well controlled diabetic retinopathy never develops.
Truth: Diabetic changes in retina are most importantly related to the duration of diabetes. A well controlled diabetic may have very advanced damage inside the eye. However it is true that if your sugars are not well controlled, these blinding changes may happen very early and reach an advanced stage very fast.

2. Vision will get affected once the damage starts.
Truth: Proliferative stage of the disease which requires treatment on priority basis, usually does not affect the vision in early stages, until it bleeds inside the eye or it goes to a stage when it can be treated only by surgery. However, it is true that vision usually gets affected in diabetic macular edema, another stage of disease which requires treatment. But since patient uses both eyes, he may not be able to pick up symptoms in one eye, until the damage is advanced. Hence it is important to have a regular eye check up by a retina surgeon to pick up these treatable stages early, so that your vision could be preserved.

WHAT DOES THE PATIENT NOTICE?

Non proliferative and Early Proliferative stages usually do not cause any symptoms. Painless loss of vision occurs only when the damage is advanced like bleeding inside the eye, retinal detachment etc. Difficulty in reading, recognizing faces, need of brighter light to read etc., are few symptoms which indicate macular edema. So if you are a well controlled diabetic with good vision, it doesn’t mean that your eyes are not damaged by diabetes.

HOW IS THE DIAGNOSIS MADE?

  1. Detailed clinical evaluation with 90 D slit lamp biomicroscopy and indirect ophthalmoscope
  2. Fundus fluorescein angiography
  3. Optical Coherence Tomography

TREATMENT MODALITIES

Treatment depends upon stage of the disease:

  1. 1. Non Proliferative stage (NPDR): It requires regular follow up usually. The interval of check up depends upon the extent of changes in your retina.
  2. Proliferative stage (PDR): The new blood vessels that form inside the eye are at increased risk of bleeding and other effects that lead to total blindness. Treatment is done by LASER to the retina sparing the central part of the retina. LASER does limit your peripheral and night vision but it is the gold standard of treatment, for this stage of the disease. LASER is not a surgery and is an OPD procedure. The aim of LASER is to dry up the new blood vessels and reduce complications. SURGICAL intervention is required in case of non resolving bleeding inside the eye and other advanced stages and is the last desperate attempt to save some vision for the patients.
  3. Diabetic Macular edema: Injections inside the eye (Intravitreal injection of Avastin/ Lucentis/ Ozurdex/ Triamcinolone acetonide) along with LASER is the treatment of choice worldwide. Multiple injections over several months to years may be required depending upon the treatment response. The aim of the treatment is to maintain the vision of the patient and prevent further vision loss.

It is very important to have strict metabolic control of blood sugar, blood pressure, cholesterol and kidney functions, to have good results with treatment. The entire treatment may fail if systemic parameters are not well controlled.

We at drishtiCONE eye care, do diabetic screening and provide all services related to diagnosis and treatment of diabetic retinopathy including LASER, intravitreal injections (avastin/ Lucentis/ Ozurdex/ Triamcinolone acetonide) and complex vitreoretinal surgeries.
EARLY DETECTION AND TREATMENT of Proliferative stage of disease and diabetic macular edema is paramount to prevent complete blindness in diabetic patients

REMEMBER: Diabetic eye disease is related to the duration of diabetes, even if the blood sugars are well controlled. Once under treatment, we try to maintain your vision and prevent further vision loss. Like diabetes is a lifelong disease, so is the eye disease due to diabetes and hence you need eye care lifelong to enjoy good vision.
