Visual Improvement following Acute Obstruction of the Retinal and Choroidal Blood Flows

ABSTRACT

The prognosis for useful vision after central retinal artery obstruction is generally considered poor, except in those cases with a patent cilioretinal artery. When the choroidal circulation is affected as well in the form of an ophthalmic artery obstruction, characteristically the visual loss is more severe and the retinal whitening is more intense and, the cherry-red spot may be present. We report a patient with partial visual improvement following acute obstruction of the retinal and choroidal circulations more than three hours.
