How is diabetic retinopathy diagnosed histologically?
[Diabetic retinopathy]() is a complication of diabetes that affects the retinal blood vessels. Histological features include microaneurysms, hemorrhages, and the formation of new, fragile blood vessels (neovascularization). These changes lead to retinal edema and exudates. Histological staining and immunohistochemical techniques are used to visualize these vascular abnormalities.
