Retinoschisis (say "ret-uh-NAW-skuh-sus") is a problem with a part of the eye called the retina. The retina is a thin nerve membrane at the back of the eye. It sends signals to your brain about what the eye sees. The retina has different layers. When you have retinoschisis, the layers have separated. Fluid may collect between the layers, forming small cysts. These changes in the retina may affect your vision, but they don't cause problems for most people.
There are two types of retinoschisis. The more common type develops as you age. It often doesn't cause any symptoms. The other type is passed down in families through genes. It affects children, mostly boys. This type is rare. It may cause vision problems that get worse over time.
Many people who have retinoschisis won't have any symptoms. But some people will notice a change in their vision. It may make things in front of you look blurry or dim. Or you may have trouble seeing things from the side of your eye.
People with this condition are at higher risk of having their retina detach, or separate, from the back of the eye. This rarely happens, but a detached retina can cause serious vision problems.
There is no treatment for retinoschisis. But you will need to have eye examinations regularly with an ophthalmologist. This is a medical doctor who treats eye and vision problems. The doctor will check to make sure that you don't have any other problems, such as a detached retina. You may be referred to an eye doctor who is a retina specialist.
