Abstract
A 68-year-old woman with a history of diabetes mellitus type 2, depression, and migraines presented with painless, acute, consecutive vision loss affecting the right eye for 1 week and the left eye for 2 weeks. Neuro-ophthalmic examination was notable for visual acuities of finger-counting peripherally, a central scotoma, anterior uveitis, vitritis, and placoid macular pigmentary changes in each eye (OU). Proprioception was diminished in the bilateral lower extremities. Optical coherence tomography (OCT) revealed hyper-reflectivity and attenuation of the outer retina OU with normal inner retinal architecture and reflectivity. Fluorescein angiography (FA) demonstrated normal filling of the central retinal arteries with patchy choroidal perfusion in the right eye and targetoid punctate foci of leakage in the macula OU. Before the recognition of intraocular inflammation and findings on OCT and FA, the patient was treated for presumed central retinal artery occlusion at an outside hospital. Additional diagnostic testing at our institution revealed an alternate diagnosis. This case highlights a rare presentation of a well-known disease entity and underscores the importance of avoiding diagnostic anchoring in clinical practice.
