AIM: To evaluate efficacy of microcatheter-assisted trabeculotomy (MAT) in eyes with secondary glaucoma after congenital cataract surgery and explore its correlation with the different degree of trabeculotomy. METHODS: A retrospective analysis was conducted on patients who underwent the said procedure between September 2019 and September 2020. The patients were classified into two groups according to the degree of trabeculotomy (group 1: ≤240-degree; group 2: 240-360-degree). The intraocular pressure (IOP) and anti-glaucoma drugs before and after operation was collected during the 12-month follow-up. RESULTS: Totally 27 eyes of 25 patients were included: 11 (40.7%) eyes in group 1 and 16 (59.3%) eyes in group 2. The mean IOP of all patients was 34.67±9.18 mm Hg preoperatively and 8.74±4.32, 9.95±5.65, 14.39±5.30, 16.02±4.37, 15.82±3.28, and 16.19±3.56 mm Hg 1d, 1wk, 1, 3, 6, and 12mo after surgery, respectively. In all patients, there were significant differences in IOP at each time point (=65.614, <0.01). In each group, IOP after surgery was lower than that before surgery (all <0.01), but there was no difference in the rate of IOP reduction between the two groups (=0.246). Furthermore, the amount of anti-glaucoma medications reduced to 0.30±0.67 (0-2) at 12mo from 2.63±0.49 (2-3) preoperatively (<0.01), and there was no difference between the two groups (>0.05). At the end of follow-up, the partial success rate was 81.8% in group 1 93.75% in group 2 (=0.549). Various amount of intraoperative and postoperative hyphema occurred in all eyes, which spontaneously absorbed or cleaned through paracentesis and irrigation. No other serious complications was observed. CONCLUSION: MAT can effectively reduce IOP in patients with secondary glaucoma after congenital cataract surgery with a high success rate and safety. And it can be used as the first choice for the treatment of secondary glaucoma after surgery for congenital cataracts.
