Central Serous Chorioretinopathy (CSCR) is a condition that affects the innermost layer of the eye responsible for sensing light and forming visual images. CSCR often affects the macula, which is region of the retina that is most important for central vision. CSCR occurs when fluid accumulates underneath the retina, forming a pocket of fluid similar to a blister. This can cause temporary or permanent damage to vision.

CSCR usually occurs in one eye, but occasionally can happen in both eyes. Symptoms of CSCR that you may notice include:
CSCR may be linked to steroid use, which can include oral or intravenous steroids, as well as steroid creams, inhalers or sprays. In some patients there may be a history of traditional medication use. Generally, we advise that patients with CSCR stop such medications where possible, to prevent the condition from recurring. However, many patients also may not have any associated medication use that triggered the CSCR.
There is also a link to stress but this is often difficult to quantify or verify.
It is not known exactly what causes CSCR, but the condition has been associated with stress, certain hormonal disruptions, and the use of steroid medications. Some traditional medicine and herbal medicine, has also been known to trigger or worsen the condition.
The risk factors of CSCR include:
An eye examination by an eye doctor can accurately diagnose the problem. Usually this is done through a clinical examination and an optical coherence tomography (OCT) scan.
In most cases, CSCR will resolve on its own over a period of weeks to months, especially if the underlying factors or medications causing the problem can be identified and stopped.
However, sometimes treatment may be offered if the problem continues, or re-occurs frequently. Current treatment options include photodynamic therapy (PDT), using a non-thermal "cold" laser together with an intravenous medication (verteporfin), or laser photocoagulation using with a thermal "hot" laser, to "seal" the leak and reduce fluid accumulation under the retina. Successful treatment does not guarantee that CSCR will not recur in the future in either eye.
