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.
