Abstract
PURPOSE: The first reported case of bilateral transient visual field defect, experienced by an ophthalmologist, which developed shortly after COVID-19 vaccination (CoronaVac, Sinovac Biotech Ltd., Beijing, China) and confirmed by computerized automated perimetry. OBSERVATION: The patient is a 42-year-old Thai ophthalmologist. He developed blurred vision within an hour after the second dose of COVID-19 vaccination. We described his self-observed of sequential symptoms, chronologic events, and management steps. The visual field of left congruous hemianopia with respect to vertical midline was detected with computerized automated perimetry. The possible mechanism could be related to an acute vasospasm of the artery in the postchiasmatic visual pathway, triggered by COVID-19 vaccine, Corona Vac. CONCLUSION AND IMPORTANCE: With increasing use of the COVID-19 vaccine in the near future, it would be prudent for medical staff and ophthalmologists to be considered and aware of this associated condition.
