What is Central Serous Chorioretinopathy?

Central serous chorioretinopathy 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.

Central serous chorioretinopathy usually affects just one eye at a time, but both eyes can be affected at the same time.
