How is retinoschisis diagnosed?
The diagnosis of retinoschisis is usually made during an examination of the back of the eye (fundus) where any splits, tears or rips may be seen. One diagnostic tool is Optical Coherence Tomography (OCT), which that uses light waves to create images of the retina.
How does retinoschisis occur?
Retinoschisis is a condition that occurs when the retina splits into two layers, affecting vision. The retina is a layer of tissue at the back of the eye. It comprises cone and rod cells, which process light coming into the eye through the pupil. The retina sends visual signals to the brain through the optic nerve.
Where is retinoschisis located?
Retinoschisis is a condition in which an area of the retina (the tissue lining the inside of the back of the eye that transmits visual signals to the optic nerve and brain) has separated into two layers. The part of the retina that is affected by retinoschisis will have suboptimal vision.
How can you tell retinal detachment from retinoschisis?
A retinal detachment typically collapses under the area of scleral depression, while a retinoschisis moves in accordance with the area of the retina that is being depressed. Retinoschisis is very clear and transparent, allowing for the choroidal detail below the schisis to be easily seen.
What is unspecified retinoschisis?
A vitreoretinal dystrophy characterized by splitting of the neuroretinal layers. It occurs in two forms: degenerative retinoschisis and x chromosome-linked juvenile retinoschisis. An inherited or acquired disorder characterized by splitting of the retina into two layers. It results in loss of vision.
Can retinoschisis resolve?
Because most of these eyes have already undergone structural changes, spontaneous resolution of myopic retinoschisis is a highly unusual event (2). Only a few dozen cases of non-surgical resolution of retinoschisis have been reported in the literature (2).
How serious is retinoschisis?
For most people, retinoschisis isn’t a serious condition. Eventually, you may need glasses to correct any vision problems caused by your split retina. While the condition itself is often harmless, both degenerative and X-linked retinoschisis increase your risk of retinal detachment.
Why would retinoschisis affect your vision?
When the retina splits, tiny lumps called cysts form between the layers. These cysts damage nerves and keep light signals from reaching the brain. Damaged nerves can make your vision blurry.
What is bullous retinoschisis?
Bullous retinoschisis is thought to result from both active secretion into the schisis cavity and vitreous traction. As the inner retinal layer expands, it becomes thinner, and holes may form in it. These holes, unlike breaks in the outer retinal layer, rarely have an effect on the schisis cavity itself.
Is retinoschisis hereditary?
Juvenile retinoschisis is inherited in an x-linked recessive pattern. The gene associated with this condition is located on the X chromosome , one of the two sex chromosomes . In males (who have only one X chromosome ), one altered copy of the gene in each cell is sufficient to cause the condition.
Is retinoschisis an emergency?
How common is degenerative retinoschisis?
Degenerative retinoschisis affects about 5-7% of the adult population. Occurrence in up to 22% of individuals older than 40 years has been reported. Both genders are equally affected.
What do you need to know about retinoschisis?
Retinoschisis is a condition in which an area of the retina (the tissue lining the inside of the back of the eye that transmits visual signals to the optic nerve and brain) has separated into two layers.
What kind of degeneration is senile retinoschisis?
Senile Retinoschisis is a microcystoid degeneration of the neurosensory retina, with splitting at the outer plexiform layer of the retina.
What are the tests for juvenile X-linked retinoschisis?
Tests for juvenile X-linked retinoschisis include: Optical coherence tomography (OCT): Light waves make pictures of the retina. Ultrasound : Sound waves create pictures of the eyes. This can show bleeding in the eye. Electroretinogram (ERG): This measures electrical activity in the retina. A special sensor is placed in each eye.
Are there any treatments for retinoschisis in children?
Large-print textbooks, computer screens, and other low-vision tools can help children in school. Bleeding in your eye is treated with a laser or with cold (cryotherapy) to close damaged blood vessels in the retina. Surgery can fix a detached retina. Researchers are testing new treatments for retinoschisis.
