Abstract: :
Purpose: To assess and compare the efficacy of transscleral cyclophotocoagulation and pars plana Baerveldt implantation to treat medically uncontrollable intraocular pressure. Methods: A retrospective review was performed of the records of all patients who received pars plana Baerveldt implant (PPBI) or transscleral cyclophotocoagulation (TSCPC) since 3/99. Results: Five eyes received PPBI and seven underwent TSCPC. Preoperative diagnosis were: neovascular glaucoma (8), open angle glaucoma (3) and angle closure glaucoma (1). The mean follow up time was 5 months in the PPBI group and 10 months in the TSCPC group. Average initial and final IOP's were 39 and 19 respectively in the PPBI group and 51 and 24 in the TSCPC group. Vision remained stable or improved in 100% of eyes with PPBI and in 71% of eyes that had TSCPC. Additional surgery for IOP control or other complications was needed in 57% of eyes in the TSCPC group and in 0% of eyes in the PPBI group. The fraction of eyes with IOP <21 on one or no medicines at last follow up was 60% in the eyes with PPBI and 29% in the eyes that underwent TSCPC. Conclusion: Although follow up was limited, the eyes that received PPBI had better post operative vision and IOP control with fewer complications than the eyes that underwent TSCPC.
