Purpose: The prevalence of central serous chorioretinopathy (CSCR) among transmasculine, polycystic ovary syndrome (PCOS), and androgen-exposed patients remains largely unexplored. Although these groups involve patients with elevated testosterone levels, previous literature is inconclusive on the influence of testosterone on CSCR. This study aimed to determine the relationship between CSCR and cohorts with exogenous androgen exposure, female-to-male (FTM) transgender individuals, and those diagnosed with PCOS.

Case reports have speculated if COVID-19 vaccinations may be associated with retinal vascular occlusions (RVO). Specifically, previous literature speculated an increased risk of RVOs days to weeks after vaccination. After reviewing two recent analyses, mRNA COVID-19 vaccinations do not appear to increase the risk of RVOs at 3 and 12 weeks post-vaccination.
