What Is Retinoschisis?

Retinoschisis is an eye condition that affects the retina, which is the light-sensitive tissue that lines the back of the eye. It happens when the retina splits into two layers. The layers can sometimes reconnect, but more often they remain separate.

Types of Retinoschisis

* X-linked juvenile retinoschisis (XLRS) is the most common type and affects males almost exclusively. It is usually inherited. Symptoms typically begin in childhood and the condition usually worsens over time.

* Senile retinoschisis occurs in older adults and is the most common type of retinoschisis. This occurs gradually and is often related to aging and nearsightedness.

Symptoms of Retinoschisis

Symptoms can include:

* Blurred vision

* Reduced peripheral (side) vision

* Trouble with night vision

* Difficulty reading

* Floaters or spots in the vision

Diagnosis of Retinoschisis

Retinoschisis is diagnosed with a comprehensive eye exam that includes:

* Visual acuity test

* Eye pressure measurement

* Examination of the retina with an ophthalmoscope

Treatment for Retinoschisis

There is no cure for retinoschisis, but treatment can help improve symptoms and prevent complications. Treatment options include:

* Eyeglasses or contact lenses to correct refractive errors

* Surgery to repair retinal detachment

Low-vision aids such as magnifiers and brighter lighting may also be helpful.

Outlook for Retinoschisis

The prognosis for retinoschisis depends on the severity of the condition. In some cases, it may lead to vision loss, but most people with retinoschisis retain good vision.

Regular eye exams are important for early detection and management of retinoschisis.
