AFFECTING FACTORS FOR SURGICAL TREATMENT OF MALIGNANT GLAUCOMA
Main Article Content
Abstract
Objectives: To evaluate the outcome and affecting factors of surgical treatment for malignant Glaucoma. Patients and Methods: Interventional, prospective study on 53 malignant Glaucoma eyes at Glaucoma department, VNEH from 10/2012 to 10/2017 with minimum follow-up of 6 months. 39 (73.6%) eyes were operated with lens removal/ IOL and vitrectomy + hyalo-zonulo-iridectomy (HZV), the remaining 14 pseudophakic eyes were treated with vitrectomy + HZV only. VA was significantly improved postoperatively, at 6 months, 51/53 eyes (96.4%) got some VA increase, while VA remained unchanged in only 2 eyes (3.8%). IOP was remarkably reduced after the surgery. The complete success rate was 67.9%, partial success rate was 30.3% and only 1 failure that needed trabeculectomy to control IOP. Preoperative VA proportionately affected visual outcome. The preoperative filtration bleb status significantly influenced the IOP results. AC depth before treatment was related with the rate of postoperative complications. Conclusion: surgical treatment including vitrectomy + HVZ (+/- lens removal) was safe and effective for malignant Glaucoma. Preoperative VA, filtration bleb and AC depth were significant prognostic factors for surgical outcome.
