Significant Visual Impairment after Short-Lasting Central Serous Chorioretinopathy

A 37-year-old man experienced two episodes of central serous chorioretinopathy (CSCR) with the onset within a 7-month period, one in each eye. The diagnosis was made based on spectral-domain optical coherence tomography (SD-OCT), fundus autofluorescence (FAF), and fluorescein angiography. The presence of subretinal neovascularization and polypoidal choroidal vasculopathy were excluded. Each CSCR episode lasted for approximately 6 months and resolved completely after laser photocoagulation (left eye) and photodynamic therapy (right eye). In the right eye, subthreshold micropulse laser treatment and oral eplerenone were initially administered because of a verteporfin shortage, but they were not effective. Final best-corrected visual acuity was 0.8 logMAR in the left eye and “counting fingers” in the right. SD-OCT revealed significant retinal thinning in both eyes despite FAF, showing no major loss of retinal pigment epithelial cells. A significant reduction of ganglion cell complex thickness occurred in the right eye. Acute CSCR can result in significant visual impairment, even when short-lasting.
