Retinal ischemia can be regarded as possible aftereffect of central retinal vein occlusion (CRVO). Ischemia means a tissue having reduced blood supply to an insufficient level. Lack of oxygen in the retinal tissue may lead to retinal cell death or cell dysfunction, and thereby, result in reduced vision. It is a common cause of visual impairment and loss of vision. The causes of retinal ischemia may be: vein and artery occlusions, diabetes and macular degeneration and more. Symptoms depend on what the ischemia is related for.
