Clinically, affected people may not have symptoms or may complain of decreased visual acuity. Ophthalmic examination may reveal signs of retinal vascular disease, including cotton-wool spots, retinal bleeds, microaneurysms, perivascular sheathing, capillary telangiectasis, macular edema, and disc edema. Capillary non perfusion, documented by fluorescein angiography, is commonly present, and extensive retinal ischemia can lead to neovascularization of the retina, iris, and disc. Staging of<unk>  has been proposed.

Diabetic retinopathy
Autoimmune retinopathy
Toxic and nutritional optic neuropathy
Hypertensive retinopathy
Photic retinopathy
