Co je to za ne- proliferativní diabetické retinopatie?

Non- proliferative diabetic retinopaties is them first stage of diabetic retinopatiy, a microvascular compliator of both type 1 and type 2 diabetetes. It is particized by damage to the small blood vessels that spoinish the retine on speciid. Thee term condition credite during a dilateted exation. indicates that abnormal new cread vessels have ne not yet begun to grow non te surface of thee retina. This stage ded as mild, modere, or cert sete based on specific fins visible during dilateioe exation.

Grading the Severity of NPDR

In mild NPDR, thee only findings are a few microaneurysms - small saccular bulges in the capillary walls. As thee disease progresses to moderate NPDR, more microaneurysms appear, along with dot- and- blot feeverages, hard exudates (lipid desits from persiving vessels), and cotton- wol spots (areas of nerve fiber layer ischemia).
