Abstract
Sectoral choroidal ischemia is a classic sign of giant cell arteritis, although the latter is more typically associated with anterior ischemic optic neuropathy or central retinal artery occlusion. We report the case of an acute choroidal ischemia in a 68-year-old, one-eyed patient, who presented with deterioration of visual acuity and metamorphopsia in his left eye (his right eye was counting fingers due to high myopia). Fundus examination revealed retinal pigment epithelium (RPE) alterations and slow choroidal perfusion on fluorescein angiography. Macular Optical Coherence Tomography (OCT) showed a total disruption of the photoreceptor layer. Although prompt corticosteroid therapy preserved some vision, secondary macular retinal pigment epithelial changes limited the visual outcome. No other ophthalmological signs were observed in follow-up.
