Synonym(s): disciform scar.

disciform scar

A subretinal scar, most often located in the macular area. It results from the haemorrhages that sometimes follow choroidal neovascularization (consisting of fibrovascular tissue) in the exudative type of age-related macular degeneration. It causes irreparable damage to vision.
