A 67YO female was referred for asymptomatic retinal findings in her right eye. She gave a history of unspecified head trauma as a child.
Optos imaging shows chorioretinal scarring with intraretinal pigment migration, extending superotemporally and inferotemporally from the optic nerve. The left fundus was completely normal.
Learning Points:
Photoreceptor loss from numerous causes, including blunt trauma, retinal detachment, macular telangiectasia, and retinitis pigmentosa (RP), can allow for intraretinal RPE migration with this shared phenotype.
Unilateral RP is exceedingly rare and requires normal electrophysiologic findings and long-term observation to ensure delayed findings in the fellow eye.
