Abstract
“Ischemia” implies a tissue damage derived from perfusion insufficiency, not just an inadequate blood supply. Mild thickening and increased reflectivity of inner retina and prominent inner part of synaptic portion of outer plexiform layer are “acute retinal ischemic changes” visible on OCT. Over time, retina becomes thinner, especially in the inner portion. Choroidal perfusion supplies the outer portion of retina; thus, choroidal ischemia causes predominant change in the corresponding tissue.
