Central serous retinopathy (CSR) is of unknown cause and typically affects healthy males between 30-50 yrs of age. It appears that any form of steroid use can provoke a CSR in some susceptible individuals.
Presenting symptoms in the affected eye include blurred or dim vision, micropsia, decreased colour vision and/or distortion. The condition is characterised by a shallow “blister” of fluid in the macular which occurs as a result of altered retinal pigment epithelial (RPE) function, whereby fluid collects under the neurosensory retina rather than being “pumped” out by the RPE.
