What is foveal Schisis?

Introduction. Myopic foveoschisis, also known as myopic traction maculopathy (MTM) or myopic macular schisis, is a relatively rare entity that affects eyes with pathological myopia (myopia >6 D).[1] These eyes often have a posterior staphyloma, which has been implicated as an etiologic factor in the pathogenesis of MTM …

What causes Schisis?

What Is retinoschisis? Retinoschisis occurs when a separation (schisis) develops between the two major layers of the retina, creating a blister-like elevation that can be confused with a true retinal detachment.

What is myopic macular Schisis?

Myopic maculoschisis (macular schisis) is fairly uncommon in Melbourne and across the world. In myopic maculoschisis, the macula seems to split because an area of the back of the eye develops an extra bulge backwards. This ‘outpouching’ is called a posterior staphyloma and can be progressive.

What is Tractional Retinoschisis?

Retinoschisis is an eye disease characterized by the abnormal splitting of the retina’s neurosensory layers, usually in the outer plexiform layer.

Can you go blind from Retinoschisis?

Retinoschisis is characterized by a reduction in visual acuity. There may also be a loss of peripheral vision. Very few people become totally blind from either form of the disorder, but some men with the juvenile form may ultimately have very poor vision.

What is vitreomacular traction syndrome?

Vitreomacular traction (VMT) syndrome is a potentially visually significant disorder of the vitreoretinal interface characterized by an incomplete posterior vitreous detachment with the persistently adherent vitreous exerting tractional pull on the macula and resulting in morphologic alterations and consequent decline …

What is the treatment for retinoschisis?

Retinoschisis usually doesn’t require treatment aside from glasses to improve your vision. However, some children with X-linked retinoschisis may have bleeding in their eye. This can be treated with either laser therapy or cryosurgery. In rare cases, children may need surgery to stop the bleeding.

Can you go blind from retinoschisis?

Does Retinoschisis cause blindness?

How is pathological myopia diagnosed?

Pathological myopia is diagnosed based on fundus examination (examination of the components at the back of the eye including the retina, the optic disc, the macula and the fovea).

Is retinoschisis curable?

There is no medical treatment for degenerative retinoschisis; however, vitrectomy surgery is occasionally required for complications related to either type of retinoschisis.

How serious is vitreomacular traction?

Sometimes, the vitreous doesn’t come away completely, leaving some of the gel attached and pulling on the macula. This then results in vitreomacular traction (VMT). If this condition is left untreated, the damage can lead to a macular hole and vision loss.

How many eyes are affected by foveomacular schisis?

A total of 22 eyes from 16 female patients and 1 male patient with foveomacular schisis were reviewed from 5 institutions. Initial visual acuity was ≥20/50 in all eyes (mean, 20/27), but visual acuity in a single eye decreased from 20/20 to 20/200 after the development of subfoveal fluid.

What kind of disease is stellate foveal retinoschisis?

Stellate foveal retinoschisis is most commonly associated with congenital juvenile X-linked retinoschisis (CXLR) due to a defect in the RS1 gene.

How is Congenital Retinoschisis complicated by combined schisis?

Congenital retinoschisis can be complicated by combined schisis–traction retinal detachment, combined schisis–rhegmatogenous retinal detachment, vitreous hemorrhage, and obscuration of the macula by the overhanging inner wall of a schisis cavity.

Can a retinal hemorrhage in schisis be treated?

The foveal and peripheral retinal splitting that occurs in schisis cannot be treated, but secondary complications may require treatment. These include vitreous hemorrhage or bleeding into the gel that fills the back of the eye (4% – 40%) and retinal detachment (5%–22%).
