• The fundus photographs of 308 patients with presumed ocular histoplasmosis syndrome (POHS) were examined. Bilateral macular involvement was found in 20% of the cases. The incidence of maculopathy, peripapillary lesions, and peripheral "punched-out" lesions in one fundus and only peripapillary changes in the fellow eye was 12%. The incidence of these features in one fundus and clinically inactive, atrophic scars in the posterior pole of the fellow eye was 23%. Twenty-five patients with atrophic lesions in the macular area of the fellow eye were followed for an average of 24 months. Six patients (24%) demonstrated activation of eight previously documented atrophic lesions resulting in macular involvement. One patient also demonstrated activation from a pre-existing juxtapapillary lesion. None of the remaining 18 patients exhibited any evidence of serous or hemorrhagic retinal sequelae in the fellow eye.
