Hyper-reflective vitreous spots in central retinal artery occlusion: An unusual finding in two cases.

HRS in the posterior vitreous have been described in inflammatory eye conditions such as uveitis, diabetic macular edema, post cataract surgery, and considered a clinical sign of inflammation. To our knowledge, the combination of CRAO and HRS has not been previously reported. The number of HRS seems to decrease over time, suggesting a role for inflammatory response in the acute stage of CRAO. A similar pathogenic process is known to occur during cerebral ischemia, where the inflammatory response may exacerbate brain injury and post-ischemic damage.
