A Cilioretinal Artery Occlusion (CLRAO) Associated with Optic Disc Edema after Viral Vector SARS-CoV-2 Vaccination: Case Report

ABSTRACT

A cilioretinal artery occlusion (CLRAO) associated with optic disc edema was diagnosed in a patient seven days after the second dose of viral vector SARS-CoV-2 vaccination. The patient developed sudden blurred vision in the inferior hemifield of the right eye. His fundus examination showed retina edema at the superotemporal quadrant within vascular arcades of the right eye. Fundus fluorescein angiography (FFA), optical coherence tomography (OCT), and optical coherent tomography angiography (OCTA) were used to confirm the diagnosis.
