Fundus photographs, ERG, and Humphrey visual fields of three PD patients. (A) Adult-onset foveomacular vitelliform-like PD: 46-year-old female (Fam7-5790) showing lipofuscin deposits in the macula, normal rod and cone responses, very minimal field loss. (B) Butterfly-like PD: 49-year-old female (Fam1-214) showing lipofusin deposits in the macula and in the periphery, decreased rod and cone responses, moderate peripheral field loss. (C) Flavimaculatus-like PD: 28-year-old female (Fam2-4957) showing peripheral deposits (seen better in fluorescein inset), decreased rod responses but normal cone responses, mild peripheral field loss.
