Central serous retinopathy is when fluid builds up under the retina. This can distort vision. The fluid leakage comes from a layer of tissue under the retina, called the choroid. There is another layer of cells called the retinal pigment epithelium (RPE). When the RPE doesn’t work as it should, fluid builds up under the RPE. As a result, a small detachment forms under the retina, causing vision to become distorted.
Most cases of CSR clear up in one or two months without any treatment. During this time, a Retina Care Center provider will look at your eye to see if the liquid is going away. Sometimes there is severe vision loss or the leakage does not go away. In these cases, laser treatment or photodynamic therapy may be used. These treatments can seal the leak and restore vision.
