Retinoschisis is a partial detachment of the retina from itself, occurring in the peripheral retina. The attached layers of the retina prevent a full retina detachment. Retinoschisis is usu
ally non-threatening and not treated. It is merely observed from year to year.
A macular hole is a complete retinal hole that occurs in the macula, that area that affects the center of vision. It occurs suddenly and usually requires treatment with a decent prognosis.
