Retinoschisis

Retinoschisis

Degenerative acquired retinoschisis is splitting of the retinal layers.  The condition can sometimes be difficult to appreciate on clinical examination especially in shallow compared to bullous retinoschisis.  The splitting of the retinal layers can occur in different layers of the retina and can sometimes involve more than one layer as seen in figure 3.  Inner and outer retinal holes can occur in the retinoschisis.
