A 30-Year-Old Man with a Recent History of COVID-19 Requiring Treatment with Corticosteroids Who Developed Bilateral Central Serous Chorioretinopathy During 7-Month Follow-Up.

BACKGROUND Central serous chorioretinopathy (CSCR) involves a localized serous macular detachment, secondary to retinal pigment epithelial and choroidal vascular changes, which can be an adverse effect of corticosteroid use. Most CSCR cases resolve spontaneously, and normal vision returns, while some chronic cases can result in blindness. This report is of a 30-year-old man with a recent history of Corona virus disease (COVID)-19 requiring corticosteroid treatment who developed bilateral CSCR with unilateral fibrin and a 7-month follow-up.
