Outcome and Complications of Combined Modified Deep Sclerectomy and Trabeculectomy for Surgical Management of Glaucoma: A Pilot Study

Purpose: To report the outcome and complications of a combined surgical technique of modified deep sclerectomy and trabeculectomy (mDST) for glaucoma. Patients and Methods: Retrospective study of 44 eyes of 43 patients with open and closed angle glaucoma who underwent mDST. Outcome measures were: Surgical Success with 3 criteria - (i) criterion 1 = intraocular pressure (IOP) = 20% of preoperative IOP or IOP >= 6 mmHg on 2 consecutive time points after 3 months; (ii) criterion 2 = IOP = 30% of pre-operative IOP or IOP >= 6 mmHg on 2 consecutive time points after 3 months and (iii) criterion 3 = IOP = 40% of preoperative IOP or IOP >= 6 mmHg on 2 consecutive time points after 3 months; IOP Reduction; Use of Anti-glaucoma Medication; Complications; Visual Acuity and Postoperative Interventions. Results: Median follow-up was 40 months (range 24-77 months). At the final follow-up visit, the mean postoperative IOP was 11.5 +/- 4.7 mmHg (p
