Axial Length Change in Eyes Treated by Silicone Sponge Scleral Buckling.

All existing medical literatue regarding axial length (AL) changes after scleral buckling surgery for retinal detachment, descibes changes after solid silicone buckling. In this hospital, the investigators use only silicone sponge buckling, which has different properties and a different buckle profile. there are no studies in the literature describing tha AL changes after sponge buckling, or whether the AL change is less or more than with solid silicone buckles. The investigators wish to determine whether the AL change profile with their silicone sponge is significantly different, and if so, whether this is clinically important in determining the better choice of buckle material to be preferred.
