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

PURPOSE

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

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.
