To evaluate the efficacy and safety of using Mitomycin-C (MMC) or Ologen implant as an adjunct to combined trabeculotomy-trabeculectomy (CTT) surgery relative to non-augmented CTT surgery in achieving higher success rates in patients with primary congenital glaucoma (PCG).A prospective triple-armed randomized controlled clinical trial was conducted in the period between April 2019 and May 2021, targeting 75 eyes of patients with PCG over one year, with patients being followed up for at least one whole year.The study included 75 eyes; only 70 fulfilled the inclusion criteria and were randomly assigned to one of the three study groups using a computer program to generate random number list. Eyes were treated by either CTT without augmentation, CTT augmented with MMC, or CTT augmented with Ologen implant. Only 63 eyes completed one year of follow-up and were evenly distributed among the three study groups; with 21 eyes in each group were statistically analyzed.Our primary outcome measure is to report and compare the percentage of patients who demonstrated complete success with intraocular pressure (IOP) controlled and maintained below 21 mmHg without the use of antiglaucoma medications or additional glaucoma surgery over a one-year follow-up. Secondary outcome measures include reporting failure, intra- and postoperative complications of the three surgical modalities, postoperative corneal diameter, clearance of corneal edema, and postoperative cup/disk (C/D) ratio.Complete success was achieved in 17 eyes (81.0%) in CTT group, 18 eyes (85.7%) in MMC group, and 17 eyes (81.0%) in Ologen group. Qualified success (IOP 21 with or without antiglaucoma medications) was achieved in 18 eyes (85.7%) in both the CTT and the Ologen groups, with 19 eyes (90.5%) in the MMC group. Failure was observed in three eyes (14.3%) in both CTT and Ologen groups and two eyes (9.5%) in the MMC group. Based on survival analysis, CTT group had a cumulative success probability of 95.2% at three months, which dropped to 85.7% at six months and remained at that level for the 9th and 12th months of follow-up. With respect to the MMC group, the cumulative success probability at three months was 95.2%, dropped to 90.5% at six months, and remained at that level for the 9th and 12th months of follow-up. While in the Ologen group, the cumulative success probability at three months was 85.7% and remained at the same level during the 6th, 9th, and 12th months of follow-up, with p value = 0.862 using the logrank test.CTT is a safe and effective primary surgical intervention in patients with PCG without the need for augmentation while preserving the augmented procedure's use for recurrent cases. |
