W. ith 15 - 18.6 million blind people in India (25% of the world’s blind population), the major causes of blindness are Cataract and Diabetic Retinopathy. Poor eye health and visual impairment result in loss of productivity and poor quality of life and disproportionately affect the afflicted population because they are not aware of the prevention and treatment possibilities, cannot access quality eye-care services due to lack of information, expense, loss of wages, and cultural and social reasons.
 Whereas the problem of sight-threatening eye diseases like Cataracts, Glaucoma, and Diabetic Retinopathy, is high there is however a major gap in services in terms of expertise, skills, or awareness to address the issue. People have to travel far to access any standard retina care.
 Retina, as a super specialty, is not available to all as it requires extremely high professional standards. There are only around 25000 ophthalmologists practicing ophthalmology in our country for a population of 1.4 billion. Of these, only about 1000 can undertake advanced V-R surgery.
      COMMON RETINAL 
DISORDERS:
Retinal Tear – Tears are due to a flap of the retina being pulled off the choroids as the vitreous shrinks
Retinal Hole– Holes are circular defects in the retina
Retinal Detachment (RD) – 
Separation of retina from the back wall of the eye 
RETINAL DETACHMENT
Diabetic Retinopathy (DR) – caused by longstanding diabetes
· Hypertensive retinopathy – 
(BRANCH RETINAL VEIN OCCLUSION) BRVO 
CENTRAL RETINAL VEIN OCCLUSION (CRVO)
,Age-Related Macular Degeneration (ARMD) 
REMEMBER: Diabetes is a common cause of blindness
w In case you are a diabetic for more than 5 years, there is a fair chance that you might have developed Diabetic Retinopathy
w You might have developed DiabeticRetinopathy, despite having good vision
w For early detection and to begin the treatment, you should see your retina specialist at regular intervals
w Diabetic retinopathy is a largely treatable condition. Early detection and treatment save eyes.
w  You should keep your blood sugar level, hypertension, increased blood lipids & cholesterol, and (kidney) disease well under control.
w Quit smoking · w Regular exercise and balanced diet
