The workup of sudden vision loss includes a thorough ophthalmic examination. Additional tests should be performed to narrow the differential diagnoses if not clinically evident and to facilitate secondary prevention in patients with a suspected ischemic, cardiac, or cerebrovascular etiology. Patients with acute retinal ischemia are at higher risk of stroke and MI, [4] so further workup and risk stratification in patients with transient monocular blindness is important for secondary prevention.
