Central retinal artery occlusion secondary to embolism?,”PlPainless loss of monocular vision is the usual presenting symptom. Embolism of the retinal artery is the most common cause of ocular stroke. CRAO is an ophthalmologic emergency. A delay in treatment may result in permanent loss of vision. Immediate intervention includes ocular massage
which dislodges the embolus to a point further down the arterial circulation and improves retinal perfusion. Hyperbaric oxygen therapy has been shown to be beneficial if given early.”
