We report a 48-year-old woman presenting with right monocular blindness due to branch retinal artery occlusion whose vision recovered due to timely paracentesis coupled with treatment with adequate antiplatelet agents and anticoagulants. The patient had transient diplopia and ptosis despite adequate antiplatelet agents and anticoagulants. Thorough search for aetiology revealed the underlying cause to be aortoarteritis. Aortoarteritis is a rare disease, and ocular involvement occurs late in the disease. We review ophthalmologic manifestation of aortoarteritis and diagnostic utilities of various modalities for aortoarteritis.
