Purpose

The aim of this study is to provide an update on this rare manifestation of ocular sarcoidosis.

Setting/Venue

Sarcoidosis most commonly manifests as acute granulomatous anterior uveitis. Posterior segment involvement is rare. Choroidal granulomas are an exceptional localization.

Methods

We report the observation of a patient who presented with a bilateral choroidal granuloma of the posterior pole in the setting of sarcoidosis.

Results

The patient was 40 years old and had been treated for pulmonary sarcoidosis. She presented with a progressive decrease in visual acuity in the right eye, which rapidly became bilateral. The examination on admission revealed a visual acuity of 2/10 in both eyes, koepe nodules in the anterior segment, and stage 1 macular edema in the fundus, with a chorioretinous appearance in the interpapillomacular area. Retinal angiography confirmed the papilledema and revealed a choroidal nodule, also visualized on OCT. The patient received a bolus of CTC and showed marked clinical and paraclinical improvement.

Conlusions

Choroidal granulomas are considered a rare manifestation of ocular sarcoidosis. The diagnosis is clinical aided by angiography and OCT, and the evolution is often good under corticosteroid therapy.
