SURGICAL MANAGEMENT OF MYOPIC SCHISIS
Myopic schisis develops in highly myopic eyes with posterior staphyloma. Elongation of eyeball and retinal traction play an important role on this pathology. Myopic schisis has a progressive nature and once retinal detachment due to macular hole develops in pathologic myopia, the prognosis of eyes is still poor even with intensive surgical treatment.
To prevent the development of macular hole retinal detachment, the surgical management of myopic schisis is considered. Currently, pars plana vitrectomy with removal of internal limiting membrane is most commonly performed. Recently fovea sparing internal limiting membrane peeling (FSIP) has been reported to minimize the risk of postoperative macular hole formation. The other approach to myopic schisis is scleral surgery which includes scleral buckling and scleral imbrication. The purpose of these scleral surgeries is to correct scleral deformity and change/ reduce retinal traction. In this topic, the outcome of these surgical options will be discussed.
