Dear Editor,

We would like to share ideas on the publication “Branch retinal vein occlusion (RVO) post severe acute respiratory syndrome coronavirus 2 vaccination.[1]” Two intriguing RVO cases were described by Tanaka et al.[1] They also observed that both instances suggested a probable link between the SARS-CoV-2 vaccination and the initial beginning of RVO.[1] Clinical medicine emphasizes the clinical influence of the COVID-19 vaccine on other systems notwithstanding the possibility of negative vaccination-related side effects. It may or may not have been a negative vaccine side effect that caused the seizure noted in the recent study. Little is known about the recipient's physical, hematological, ocular, or immunological status before immunization. Because there is no conclusive proof connecting immunization to RVO, making a decision is difficult. Even after receiving vaccinations, a person may already be unwell. The vaccine recipient could also develop a different disease. A co-infection may also appear following the COVID-19 vaccine.[2] For instance, dengue can result in ocular problems if it co-occurs.[3],[4] It is necessary to conduct another prospective analysis of the COVID-19 vaccine's effects on individuals with complete clinical histories. When an incidence has been recorded, a comprehensive laboratory analysis is required to rule out other possibilities.
