Purpose:
To analyze sequential chorioretinal changes in presumed ocular histoplasmosis syndrome (POHS) using volumetric spectral-domain optical coherence tomography (SD-OCT).
Methods:
A total of 28 treatment-naive eyes of 20 POHS patients were characterized as: no choroidal neovascular membrane (CNVM) at initial SD-OCT but CNVM development during follow-up (primary group); CNVM at initial SD-OCT (progressive group); and contralateral asymptomatic eyes (control group).
Results:
The primary group (4/28 eyes) initially demonstrated external limiting membrane (ELM), ellipsoid zone and retinal pigment epithelium (RPE)/Bruch's disruption in 100%, and pigment epithelial detachment (PED) in 75% of eyes. CNVM developed in 100% of eyes during follow-up. Progressive group (8/28 eyes) showed CNVM in 100% of eyes. Control group (16/28 eyes) showed ELM disruption in two and PED in three additional eyes on follow-up from initial analysis.
Conclusions:
SD-OCT is a useful tool to sequentially follow eyes with POHS for subtle chorioretinal changes that may suggest impending CNVM development, and thus benefit from closer clinical monitoring.
