Central serous chorioretinopathy (CSCR) is characterised by retinal serous detachment usually localised in the macular region. CSCR predominantly affects men between 30 and 50 years of age. Traditional classification differentiates between acute (duration shorter than 4 to 6 months) and chronic disease (duration longer than 4 to 6 months). The pathogenesis is multifactorial and current thinking assumes the presence of localised choroidal hyperpermeability with subsequent secondary changes in the retinal pigment epithelium (RPE). The symptoms of acute CSCR include central blurred vision, often with deterioration in visual acuity. Optical coherence tomography (OCT) reveals subretinal fluid (SRF) and/or single retinal pigment epithelial detachments. Fluorescein angiography (FA) usually shows a leaking point with absent or only minor RPE changes in the acute phase and indocyanine green angiography (ICG) highlights circumscribed areas of thickened and hyperpermeable choroid. Acute cases may show spontaneous resolution of SRF, but may also recur and/or become chronic. After the initial diagnosis, spontaneous remission is seen in about 70 to 80% of cases, with a recurrence rate of about 50%. Due to the favourable spontaneous course, it is recommended to wait for 4 to 6 months after the first symptoms manifest. Steroid therapy is considered as a major risk factor. Chronic cases are characterised by slow deterioration in visual acuity with reduced contrast and colour perception. There are extensive RPE changes, with secondary degenerative changes of the photoreceptors. The disease can by complicated by choroidal neovascularisation (CNV), especially in elderly patients. The literature lists a number of treatments: The leakage point (visible in the FA) can be treated by focal laser therapy, either micropulse laser or, if sufficiently distant from the fovea, by argon laser coagulation. Randomised trials in chronic CSCR demonstrated good outcomes with photodynamic therapy. With observation periods ranging from 3 to 6 months, several case series reports found improvement after systemic administration of mineralocorticoid receptor antagonists, carbonic anhydrase inhibitors or non-steroidal anti-inflammatory drugs. In the presence of secondary CNV, anti-VEGF treatment should be initiated. It is unclear whether the combination with PDT might be useful.
