Correlations between intraocular pressure and resulting scleral indentation after detachment surgery

The correlation of IOP, cerclage diameter and cerclage buckle height was examined experimentally for different silicone band profiles. The smallest cerclage diameter was found at the lowest IOP whereas a maximal buckle height was reached with an IOP between 10 and 15 mm Hg. For clinical application a maximal vitreous traction relief is expected with minimal IOP. The maximal buckle height in order to reach an optimal drainage barrier occurs with an IOP between 10 and 15 mm Hg.
