Safety, efficacy, and patient selection of ripasudil in patients with uncontrolled glaucoma with maximum conventional medical therapy.

PURPOSE

Ripasudil hydrochloride hydrate (0.4%) is the first Rho-associated protein kinase (ROCK) inhibitor eye drop that lowers intraocular pressure (IOP) by increasing conventional aqueous outflow through the trabecular meshwork and Schlemm's canal. We aimed to evaluate the safety and efficacy of ripasudil in patients using the maximum topical anti-glaucoma medications and with uncontrolled IOP.

METHODS

In our prospective interventional study, we enrolled 27 eligible and consenting patients (46 eyes) who presented to us between January 2021 and June 2021. Ripasudil 0.4% was added as adjunctive therapy to the ongoing glaucoma treatment. On follow-up visits at 7 days, 15 days, 1 month, 2 months, and 3 months, the visual acuity, IOP with applanation tonometer, anterior segment, and fundus were evaluated. The IOP before and after the use of ripasudil eye drops was compared by paired t-test.

RESULTS

Among the 27 patients, 18 were males and 9 were females. A statistically significant reduction in IOP was noted at all time durations (P < 0.00001) with the maximum reduction at 3 months with all patients achieving their target IOP. No patient developed any side effects necessitating the omission of ripasudil. The most common adverse event noted was conjunctival hyperemia (22 patients), which was mild and transient.

CONCLUSION

Ripasudil showed additional IOP-lowering effect with other antiglaucoma medications and exhibited no significant side effects.
