Central Serous Retinopathy (CSR) is a condition in which a small pool of fluid collects under the central retina.  A defect in the normally water tight layer beneath the retina allows the leakage of fluid which then collects under the retina.  This forms a blister-like elevation which alters the function of the retina, and typically becomes noticeable when central vision is affected.  CSR most commonly occurs in males in their 30's to 50's.  The cause of CSR is unknown, although the condition is commonly associated with stress or “type A” personalities.  

Symptoms of CSR

The symptoms of an eye affected by CSR are blurred vision, distortion, or a central grey or dark spot, The vision can range from 20/20 to 20/200.  Color vision may also be effected.

Diagnosis of CSR

The diagnosis of CSR is usually made by its characteristic clinical appearance.  Fluorescein Angiography may be necessary to confirm to diagnosis.  In Fluorescein Angiography, a dye is injected into an arm vein, and photos are taken as the dye passes through the retinal blood vessels.  During this test the defect in the layer beneath the retina can be identified, as leakage of dye through it is typically seen.

Treatment for CSR

In the majority of the cases no treatment is required. And the condition resolves spontaneously within several months.  There is no medication known that will improve CSR.  In some cases, laser treatment to cauterize the leakage source can speed resolution of the fluid blister and improve vision.  Behavior modification may be recommended if stress is thought to be a contributing factor.
