Abstract

Purpose: To compare the control of intra ocular pressure (IOP) after trabeculectomy with adjunctive use of Mitomycin–C (MMC) versus Bevacizumab.
Study Design: Quasi experimental study.
Place and Duration of Study: Al-Ibrahim Eye Hospital, Isra Postgraduate Institute of Ophthalmology, Karachi, from August 2017 to August 2019.
Methods: One hundred and six patients of either gender, fulfilling the inclusion criteria were planned for trabeculectomy with adjunctive use of Mitomycin-C (MMC) or Bevacizumab. Each group consisted of 53 patients (53 Eyes). The patients diagnosed with Primary Open Angle Glaucoma (POAG) with IOP ? 21 mm Hg and not controlled with topical anti-glaucoma medication were selected. Data were analyzed by using SPSS Version 22.0. Independent sample t test was used to check significance between two drugs. Paired sample t test was used to check significance of pre and post-operative IOP.
Results: Mean age of patients was 56.67±7.34 years. Mean preoperative IOP was 31.51 ± 9.66 mm Hg in MMC group and 29.21 ± 7.69 mm Hg in Bevacizumab group. At first postoperative day, mean IOP after use of MMC was 14.75 ± 9.46 mm Hg and for Bevacizumab was 15.07 ± 6.47 mm Hg (p-value 0.001). Similarly, at one year follow-up, mean IOP for MMC group was 11.26 ± 2.31 mm Hg and for Bevacizumab was 11.73 ± 2.12 mm Hg (p-value 0.001).
Conclusion: There was significant reduction in IOP in both MMC and Bevacizumab groups. However, the difference between the two groups was not statistically significant at mean follow-up of one year.
