A case illustrates the diagnosis of butterfly-shaped pigment dystrophy in a rare condition, indicating complexities in ocular pathology.
This 44‐year‐old patient showed a distinctive bilateral pigmentary lesion of the macula which led to the tentative diagnosis, butterfly‐shaped pigment dystrophy of the fovea. This is an extremely rare condition, with only a handful of cases reported in the literature. The disease is described, along with the rationale used in making the diagnosis.
