Adjunctive use of netarsudil 0.02% in the treatment of refractory glaucoma: a one year analysis

TL;DR

This study shows that adding netarsudil to existing treatments significantly lowers eye pressure in patients with hard-to-treat glaucoma over a year.

Contribution

The study demonstrates the long-term effectiveness of netarsudil as an adjunct therapy for refractory glaucoma.

Findings

Patients showed statistically significant IOP reductions at 3, 6, and 12 months after adding netarsudil.

The largest IOP reduction was observed at the 12-month follow-up.

Most patients maintained stable IOP without needing additional surgery.

Abstract

This study evaluates the long-term adjunctive use of netarsudil ophthalmic solution 0.02% in lowering IOP in patients with refractory glaucoma.

This retrospective chart review study was conducted at a tertiary care center. Patients who were prescribed add-on netarsudil therapy and on ≥ 3 topical glaucoma medications from 01/01/2018 to 08/31/2020 were reviewed. 47 patients (69 eyes) met the inclusion criteria. Baseline IOPs prior to the addition of netarsudil were compared to IOPs measured at 3-, 6-, and 12-month intervals. Any patients with inadequate follow-up or who had glaucoma surgery after netarsudil initiation were excluded.

Median baseline IOP (± SD) was 21 ± 5.8 mmHg (median of 2 visits prior to initiation of netarsudil). At 3-month follow-up, 64 eyes had a median IOP of 16 ± 6.7 mmHg (p < 0.01). At 6-month follow-up, 56 eyes had a median IOP of 18 ± 4.6 mmHg (p < 0.01). At 12-month follow-up, 44 eyes had a median IOP of 15 ± 6.8 mmHg (p < 0.01). At the conclusion of the study, 64% of eyes reached 1 year follow-up due to several reasons.

Patients with refractory glaucoma showed statistically and clinically significant IOP reductions on netarsudil. IOP reduction was stable long-term with the largest decrease in IOP seen at 12 months. Although some patients will still go on to require further laser or incisional surgery, for most patients netarsudil is an effective treatment for adjunctive use in refractory glaucoma.
