Influence of postoperative lens status on intraocular pressure and corneal endothelium following vitrectomy with silicone oil tamponade]

To evaluate the influence of postoperative lens status on intraocular pressure elevation and corneal endothelial cell loss in patients who underwent pars plana vitrectomy with silicone oil injection for the management of complex retinal detachment.The medical records of 80 eyes of 79 patients who underwent silicone oil removal were reviewed retrospectively. For analysis, eyes were divided by postoperative lens status into 2 groups: pseudophakic eyes (IOL group) and aphakic eyes(aphakic group).There was a significantly greater decrease in intraocular pressure after silicone oil removal in the aphakic group but not in the IOL group. As compared with the IOL group, the aphakic group showed a significant reduction in endothelial cell density at the time of silicone oil removal.Patients who underwent silicone oil injection with pseudophakic eyes may have a lower risk of intraocular pressure elevation and corneal endothelial cell loss than those with aphakic eyes.
