Presumed Ocular Histoplasmosis

Twenty-one persons with nondisciform scars suggestive of histoplasmosis were identified during a community survey for ocular histoplasmosis. A classification of characteristic and "questionable" scars was developed. One hundred sixty-three scars were analyzed in 42 eyes, with a range of 1 to 70 scars and a mean of 7.8 scars per patient. Most cases had from one to four scars. Peripapillary scars were present in 28% of cases. Scars were bilateral in 62%. Three persons had paramacular scars. Fluorescein angiography did not reveal any "activity" in the peripheral scars although some leakage was observed in one peripapillary lesion.
