A Comparative study of Non-penetrating deep sclerectomy versus trabeculectomy in bilateral primary open-angle glaucoma at tertiary health care center
Journal Title: MedPulse -International Medical Journal - Year 2017, Vol 4, Issue 4
Abstract
Background: Trabeculectomy is the commonly performed surgical procedure for treatment of glaucoma. Despite of numerous advantages over full-thickness procedures, it can cause undesirable early postoperative complication. NPDS is used for the surgical treatment of medically uncontrolled open angle glaucoma and was developed to avoid the complications of trabeculectomy procedure. This study was undertaken to assess the safety and efficacy of deep sclerectomy versus trabeculectomy. Material and Methods: A total of 70 eyes of 35 patients with uncontrolled bilateral primary open-angle glaucoma (intraocular pressure of 21 mmHg) despite maximally tolerated medications underwent trabeculectomy in one eye and NPD Sin other eye over a period of 6 months. Results: Significant OP reduction was seen in both groups during follow up period. However, in the trabeculectomy group there was a statistically significant reduction. Less number of cases required postoperative antiglaucoma medications in trabeculectomy group. More complications such as hyphaema, conjunctival leak, flat or shallow anterior chamber and uveitis were noted in trabeculectomy group. Discussion: NPDS was found to be a saferprocedure, with fewer postoperative complications, which were less severe, compared with trabeculectomy. In conclusion, NPDS and trabeculectomy offered comparable IOP reduction, visual outcome, and need for postoperative glaucoma medications. In cases where larger reduction in IOP is required trabeculectomy is a better method than NPDS.
