ABSTRACT
Seven patients with scars typical of ocular histoplasmosis syndrome presented with new symptoms of decreased vision or metamorphopsia. In each patient the symptoms corresponded to an atrophic or "punched-out" histoplasmosis scar in the macula. Clinically, a small amount of subretinal fluid overlying the scars and slight hyperfluorescence were seen on fluorescein angiography. These findings were due to a choroidal neovascular membrane growing within the margins of the atrophic scar. The membranes were difficult to diagnose because of the absence of hemorrhage, pigmentation, or growth of vessels beyond the margins of the scar. Clinicians should be aware that these patients may have early and growing choroidal neovascularization and may need to undergo photocoagulation or to be followed closely.
