Proliferative Diabetic Retinopathy
Diabetic retinopathy (DR) is the leading cause of visual impairment worldwide. It almost accounts for 2.6% of treatable blindness globally (1). It is estimated that the overall prevalence of diabetic retinopathy is 34.6 % worldwide, while the prevalence of proliferative diabetic retinopathy (PDR) is 6.96% and that of vision-threatening DR (VTDR) is computed to be 10.2% (2). Currently, the prevalence of PDR in India is estimated to be 17% which is significantly higher compared to patients from other locations of Asia (3). Early detection and treatment is the only key to avoiding complications and risks of vision loss (4). But the major obstacle ahead of us in India is the failure to diagnose DR in early stages; as it is observed that only 18–35% of diabetics undergo ophthalmologic evaluation regularly (5).
