Central Serous Chorioretinopathy: A Review of Pathogenesis, Risk Factors, Diagnostic Methods and the Current Treatments

Abstract

Central serous chorioretinopathy (CSCR) is characterized by serous detachment of the neurosensory layer at the macula. It has a relatively high recurrence rate and mainly affecting middle-aged males. The etiology and pathogenesis of the disease still remain ambiguous. But choroidal changes which increase choroidal vascular permeability are the basic pathology of CSCR. Different diagnostic methods such as FAF, FFA, OCT, OCTA, ICG could be used to detect its biomarkers such as choroidal thickness, choroidal vascularity index, hyperreflective dots for exact diagnosis and treatment response. Acute CSCR generally self-limited, but in recurrent or chronic forms may cause permanent visual loss due to progressive and irreversible damage in the photoreceptor layer of retinal pigment epithelium atrophy. Several treatment alternatives have been reported, such as PDT, intravitreal Anti-VEGF, TTT, Laser, Mineralocorticoid receptor antagonist for chronic and recurrent CSCR.
