Late-Onset Retinal Degeneration (L-ORD)

A genetic retinal disorder. Onset typically occurs in a person’s fifth to sixth decade. Symptoms include night blindness, progressing to severe central and peripheral degeneration with choroidal neovascularization and chorioretinal atrophy. Because it is late onset, it is often mistaken for regular macular degeneration. Note, however, that this disorder, in its severest state, affects both central and peripheral vision and thus leads to total blindness, unlike some more common macular disorders.
