IOTM: Branch Retinal Artery Occlusion
This 52 year-old patient presented with a sudden central visual field defect in the right eye for two days. Visual acuity, intraocular pressure and anterior segment were unremarkable. Visual field testing revealed a horizontal circumscribed defect from the optic nerve, beyond the macula, inferior to the fovea. (Image A) Fundus photography demonstrated an occlusion of a cilioretinal artery (branch retinal artery occlusion). (Image B) The horizontal SS-OCT (Image C) and vertical SS-OCT (Image D) through the branch retinal artery occlusion clearly demonstrate retinal ischemia.
