Low Endogenous Recanalization in Embolic Central Retinal Artery Occlusion—The Retrobulbar “Spot Sign”

Abstract

The hyperechoic spot sign may be an important predictive prognostic marker for persistent loss of vision. Its persistence may indicate calcified or cholesterol emboli and may explain the low therapeutic success rate to thrombolysis. Further studies on their origin and significance in atherosclerotic disease are warranted.
