Central Serous Chorioretinopathy

Central serous chorioretinopathy is a condition in which fluid builds up under the retina at the macula, causing blurred or distorted central vision, most often in one eye.

Common symptoms

Blurring, dimming, or distortion of central vision, objects appearing smaller or further away, and a dark or washed-out patch near the centre of sight.

Description

Central serous chorioretinopathy, often shortened to CSR, happens when fluid leaks from blood vessels beneath the retina and collects in a small blister under the macula. This lifts the retina slightly and distorts how images are focused.

The condition is most common in men aged 30 to 50 and has been linked to stress, steroid medicines, sleep apnoea, and type A personality traits. Many episodes settle on their own over a few months, though some people experience recurrent or persistent fluid.

Management usually starts with observation and lifestyle changes, including reducing steroid use where safe. If fluid persists or recurs, treatments such as focal laser, photodynamic therapy, or eye injections may be considered to protect long-term vision.
