Chronic elevation of blood glucose causes progressive microvascular damage to the delicate retinal capillaries. In the early stages (Non-Proliferative Diabetic Retinopathy or NPDR), weakened capillary walls develop balloon-like swellings (microaneurysms) and leak fluid, blood, and fatty deposits into the retina.
When fluid accumulates in the central macula (Diabetic Macular Edema), central reading vision blurs. In advanced stages (Proliferative Diabetic Retinopathy or PDR), oxygen deprivation triggers the growth of fragile, abnormal new blood vessels that can rupture, causing catastrophic vitreous bleeding. At Drishti Eye Clinic in Jammu, Dr. S.P. Sharma uses state-of-the-art retinal lasers and anti-VEGF protocols to seal leaking vessels and halt disease progression.
