Choroidal Ischemia

Choroidal ischemia is hypoperfusion of the choroidal circulation, associated with giant-cell arteritis, hypertensive emergency, or ocular ischemic syndrome. Clinical: acute/subacute blurred vision with choroidal infarcts on fundus exam. If giant-cell arteritis suspected, urgent systemic corticosteroids to prevent bilateral blindness. Otherwise treat underlying vascular cause.

Causes and Pathogenesis

Large-vessel vasculitis/hypertension/ischemia hypoperfuses the choroid.

Treatment

Urgent systemic steroids if GCA suspected; treat underlying vascular cause

Preventive Measures

Urgent GCA treatment; control vascular risk.
