Abstract

Diabetic retinopathy refers to pathology of the capillaries, arterioles and venules in the retina and the subsequent effects of leakage from or occlusion of the small vessels. Changes that occur within the retinal capillary wall include: thickening of the basement membrane; pericyte loss; epithelial cell dysfunction (loss of epithelial tight junctions); and loss of endothe‐lial cells. The lesions that the Early Treatment Diabetic Retinopathy Study (ETDRS) described as critical to the stages of progression of diabetic retinopathy are microaneurysm, haemorrhage, and HMas. There are a number of different classifications of diabetic retinopathy which have been developed to give indications of the risks of progression to proliferative diabetic retinopathy or vision‐threatening maculopathy, and the appropriate referral criteria, the latter depending on individual healthcare systems. The key factor in these classifications is accurate identification of the lesions that occur in diabetic retinopathy.
