PURPOSE: The purpose of this study was to compare the outcomes of microcatheter-assisted trabeculotomy to circumferential trabeculotomy using the rigid probe trabeculotome in primary congenital glaucoma. METHODS: This retrospective study was performed in an institutional setting. The medical records of primary congenital glaucoma patients who underwent circumferential trabeculotomy (≥270 degrees incised) using Glaucolight-illuminated microcatheter or a rigid probe trabeculotome were reviewed. The primary outcomes were the percent reduction of intraocular pressure (IOP) and success rates. Complete success was defined as achieving an IOP<18 mm Hg without medications. Secondary outcomes were the postoperative IOP and glaucoma medications. RESULTS: The study included 92 eyes of 92 patients. Of these, 33 eyes of 33 patients aged 6.4±8.7 months underwent microcatheter-assisted trabeculotomy creating a 336±34-degree incision, with 19 eyes (58%) having a complete 360-degree incision. The other 59 eyes of 59 patients aged 8.2±13.1 months underwent 2-site trabeculotomy, using a rigid probe trabeculotome through a combined superonasal and inferotemporal approach, creating a 338±29-degree incision, with 33 eyes (56%) having a complete incision. After a follow-up of 21.2±8.9 months, there was a 42%±25% IOP reduction and a 73% rate of complete success in the microcatheter group, compared with 40%±22% IOP reduction and an 80% success rate in the rigid probe group (P=0.7 and 0.3, respectively). There was no significant difference in survival time in both groups (P=0.6). CONCLUSION: Circumferential trabeculotomy using either the illuminated microcatheter or rigid probe trabeculotome yielded comparable results; however, the added cost of the microcatheter should be considered.
