Abstract

Scleral buckles have important biomechanical effects on the eye when used for the treatment of rhegmatogenous retinal detachments. These include changes in the axial length, volume, refractive error, and ocular rigidity. Indentation of the peripheral retina by the scleral buckle helps relieve vitreous traction on retinal tears and decrease fluid movement into the subretinal space. Scleral buckles combined with drainage of subretinal fluid and creation of chorioretinal adhesion promote retinal reattachment. Understanding the effects of scleral buckles helps retinal surgeons comprehend the biomechanics of retinal detachments and ways in which scleral buckles or vitrectomy can most effectively help them treat detachments.
