Purpose: To present a case of branch retinal vein occlusion (BRVO) following ChAdOx1 nCoV-19 (Oxford-AstraZeneca) Vaccine. Methods: Case report. Results: A 60-year old otherwise healthy Caucasian male, presented to the ophthalmology emergency clinic complaining of sudden, painless vision loss in his right eye of 24 h” duration. The patient had received Vaxveria seven days prior. The clinical and fundus examination of the right eye established the diagnosis of BRVO. Conclusion: The present case descibes the occurrence of BRVO soon after the vaccination with the Oxford-AstraZeneca vaccine. The close temporal relationship between the BRVO incidence and the vaccination is reinforced by the lack of othe subjective cause to justify the episode. © The Author(s) 2022
