(I) Background or Non-proliferative diabetic retinopathy (NPDR) and (II) Proliferative diabetic retinopathy (PDR)
The NPDR condition is the early stage of this disease with mild and nonexistent symptoms, the blood vessels get weakened leading to the formation of bulges microaneurysms with leakage of fluid to retina, it results into swelling of macula. On the other hand, PDR is basically different and advanced stage of the disease, being followed by growth of abnormal and weak blood vessels in retina & vitreous, their leakage often leads to clouding vision and more serious complications.
One more general question: What is Retinal Detachment (RD)?
Retina is the light-sensitive layer of tissue that lines the inside of the eye and sends visual messages through the optic nerve to brain. When the retina detaches it is lifted or pulled from its normal position. If not promptly treated, Retinal Detachment can cause permanent vision loss. Procedure of Cryopexy, Laser treatment and Vitrectomy are often performed to treat such retinal detachments.
