Central serous retinopathy (CSR), also known as central serous chorioretinopathy, is an eye disease which causes visual impairment, often temporary, usually in one eye. When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula. This results in blurred or distorted vision. A blurred or gray spot in the central visual field is common when the retina is detached. Reduced visual acuity may persist after the fluid has disappeared.
The disease is considered of unknown cause. It mostly affects white males in the age group 20 to 50 and occasionally other groups. The condition is believed to be exacerbated by stress or corticosteroid use.
Observation is usually recommended for short periods of time, 2-3 months due to the high rate of spontaneous resolution but in chronic cases, treatment such a low fluency PDT is an option.
