What is Central serous chorioretinopathy?
Central serous chorioretinopathy (CSCR) is characterised by a fluid “blister” under the central retina (the macula) – the area of sharp central vision. This is due to a disturbance to specialised cells called the RPE (retinal pigment epithelial cells) that form a barrier between the retina and the underlying blood vessel layer, called the choroid. In most cases these are abnormally distended (known as pachychoroid). Symptoms include blurred vision or distortion (straight lines or objects seeming curved).
