Central serous chorioretinopathy Central serous retinopathy

Central serous chorioretinopathy (CSCR) appears to occur when fluid leaks from the choroid into the subretinal space through a defect in the retinal pigment epithelium (RPE).

This results in localised elevation and detachment of the retina. As the macula is involved in more than two-thirds of cases, central vision is usually affected. Patients often describe significant psychosocial stressors preceding the disease onset, and it is suspected that increased serum corticosteroid or catecholamine levels may play a role.
Animal studies, as well as an increased incidence in patients taking steroid medications, support this proposition.

Symptoms

CSCR is usually unilateral. Common symptoms are blurred vision, micropsia (objects appearing unusually small) and metamorphopsia (distorted shapes).
