Central serous retinopathy (CSR) is caused by leakage of fluid beneath the retina. This bubble or blister of fluid beneath the macula can cause a central scotoma, minification, and blurred vision. CSR is typically seen in males between 20 and 40 years of age and has been associated with stress and "Type A personality". Patients who are pregnant, use steroids or has a history of organ transplantation are at risk too.
The condition usually resolves spontaneously over weeks to several months, but can be chronic. Photodynamic therapy (PDT) or focal laser treatment may be used to help speed up the recovery process in some cases. Fluorescein angiographys is useful in cases when the diagnosis is questioning, in chronic cases, and when laser treatment is considered.
