# Central serous chorioretinopathy (CSC)

Central serous chorioretinopathy is a condition where fluid collects under the central retina. This creates a small blister under the macula, causing blurred or distorted vision.

## Who gets CSC and why

CSC often affects younger to middle-aged adults, more commonly men. Stress and steroid medicines are recognised risk factors.

- Patients may notice a grey patch, central blur, or straight lines looking bent.
- Colours sometimes appear washed out or darker in the affected eye.
- Vision is usually better when using both eyes together.
- OCT scans show fluid under the macula.
- Fluorescein angiography may pinpoint the leakage site.

## Course of the condition and treatment

Most cases resolve on their own over weeks to months. Treatment is considered if fluid persists or recurs frequently.

- Observation and stress reduction are often the first steps.
- Stopping or reducing steroid medicines may help when safe to do so.
- Laser or photodynamic therapy can seal persistent leakage points.
- Vision generally improves but may not return fully to normal contrast.
- Regular monitoring detects recurrences early.
