Localized foveal detachment in a patient with central retinal artery occlusion with cilioretinal sparing

Purpose To report the optical coherence tomography (OCT) findings of acute central retinal artery occlusion (CRAO) with cilioretinal sparing. Methods Optical coherence tomography findings in a 45-year-old man with CRAO with cilioretinal sparing were evaluated. Results Optical coherence tomography disclosed diffuse thickening of the neurosensory retina in the perifoveolar area. Increased reflectivity was noted in the inner retinal layers. The hyporeflectivity is observed in the outer retina including the outer neurosensory retina. The photoreceptors are not seen because of the shadowing effect. A localized foveal detachment composed of a dome-shaped retinal elevation over a nonreflective cavity with minimal shadowing of the underlying tissues was seen. Conclusions The OCT findings showed that besides the usual OCT findings in acute CRAO, the presence of a cilioretinal artery might lead to the leakage of fluid into the subfoveal space leading to localized detachment.
