Brief Summary
|
•CSCR is a retinal disorder caused by choroidal vascular abnormalities, resulting in subretinal fluid (SRF) accumulation and disturbances in retinal pigment epithelium (RPE) function. •Patients experience significant impairment in qualitative visual functions—such as contrast sensitivity, colour vision, and metamorphopsia—that can persist even after SRF resolution. •Laser photocoagulation accelerates SRF resolution, but its role in preserving visual functions remains unclear. •This study aims to investigate whether early laser photocoagulation in acute CSCR can mitigate the loss of qualitative visual functions compared to conventional observation. |
