Retinoschisis

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.

Call your doctor now or seek immediate medical care if:

• Your vision changes.
• You see new flashes or floaters.

Watch closely for changes in your health, and be sure to contact your doctor if:

• Your symptoms get worse.
