Stroke: Retinal changes predict subsequent vascular events in ischemic stroke.

摘要

Changes in retinal microvasculature can predict recurrent vascular events in patients after ischemic stroke, according to a recent study published in Neurology.Improvements in acute care of patients with stroke have resulted in decreased mortality; however survivors are at risk of recurrent vascular events. Retinal imaging is a noninvasive technique that can be used to identify changes in retinal microvasculature. Signs of microvascular changes in the retina have been found following cerebrovascular events (such as stroke) in healthy populations. As retinal microvasculature has a common arterial supply and many similar features to brain microvasculature, identifying changes in the retina could provide prognostic information about cerebrovascular events.
