Central serous retinopathy (CSR) is a condition in which a patient develop pockets of fluid under the retina, usually in the macula. This may cause distortion or blurred vision. This is usually a self-limited condition and vision generally recovers on its own within a few months.
CSR typically affects adults between the ages of 20 and 50. People with CSR often find that their retinal swelling resolves without treatment and their original vision returns within six months of the onset of symptoms. Some people with frequent episodes may have some permanent vision loss. Recurrences are common and can affect 20% to 50% of people with CSR. If retinal swelling persists for more than three or four months, or if an examination reveals early retinal degeneration, laser surgery may be helpful. While the cause of CSR is unknown, it has been related to stress, steroid use, and obstructive sleep apnea.
