What is the grading for diabetic retinopathy?
Grading classification for proliferative DR (R3) The new classification consists of 2 categories – R3A (active proliferative retinopathy) and R3S (stable treated proliferative retinopathy). This allows for urgent attention where disease is active.
What is R2 in diabetic retinopathy?
Pre-proliferative retinopathy (R2): The retina can become starved of oxygen, called ischaemia, which increases the risk of sight loss.
What does r1 background retinopathy mean?
Stage 1: background retinopathy This means that tiny bulges (microaneurysms) have appeared in the blood vessels in the back of your eyes (retina), which may leak small amounts of blood. This is very common in people with diabetes.
What is venous beading?
Venous beading refers to irregular constriction and dilatation of venules in the retina. “Beading” is a non-specific sign of retinal ischemia. It is a good predictor of risk for retinopathy progression if present in two of the four midperipheral retinal quadrants. 37.
What is moderate nonproliferative diabetic retinopathy?
Moderate nonproliferative diabetic retinopathy includes the presence of hemorrhages, microaneurysms, and hard exudates. With this condition, soft exudates, venous beading, and intraretinal microvascular abnormalities (IRMA) occur less frequently than with severe NPDR.
What is mild nonproliferative diabetic retinopathy?
Mild Nonproliferative Retinopathy It means that there are tiny bulges in the tiny blood vessels in your retinas. The bulges are called microaneurysms. They may cause the vessels to leak small amounts of blood into your retinas.
