[The volume and dimensions of eyeball analyzed by MRI following encircling scleral buckles].

Objective: To assess the changes of the volume and dimensions of the eyeball and the vitreous following encircling scleral buckle.

Methods: 26 eyes from 26 patients received successful broad-band encircling scleral buckles for rhegmatogenous retinal detachment from July 2002 to December 2003.
