BACKGROUND: To examine the use of ripasudil as a trabeculotomy outcome marker in patients with primary open-angle glaucoma (POAG). METHODS: Between May 2015 and December 2018, 35 eyes underwent trabeculotomy and were postoperatively followed for over 3 months. Ripasudil was defined as effective if drug administration resulted in a greater than 10% reduction in intraocular pressure (IOP). Patients were divided into effective (effective group) or non-effective (non-effective group) ripasudil administration groups. The need for additional glaucoma surgery or an IOP ≥ 21 mmHg indicated surgical failure. In both groups, a Kaplan-Meier survival-analysis was used to evaluate success probabilities related to postoperative IOP levels. RESULTS: Effective IOP reduction occurred in 14 of 35 eyes after ripasudil administration, which was shown by a decrease of more than 10%. Postoperatively, both groups exhibited significant reductions of IOP and antiglaucoma medication use for up to 24 months. At 12 and 24 months after trabeculotomy, probabilities of success in the effective vs. non-effective group were 100% vs. 94.7 and 100% vs. 75.4%, respectively (P = 0.14). CONCLUSIONS: Trabeculotomy is effective for achieving an IOP < 21 mmHg in ripasudil effective POAG eyes. Examination of ripasudil's IOP-lowering effects may be useful in predicting surgical outcomes after trabeculotomy.
