One-Year Efficacy and Safety of Omidenepag Isopropyl in Patients with Normal-Tension Glaucoma.

Purpose: To retrospectively evaluate the 1-year efficacy and safety of single-agent of omidenepag isopropyl in patients with normal-tension glaucoma (NTG).

Methods

One hundred patients (100 eyes) newly administered omidenepag isopropyl were enrolled. Intraocular pressure (IOP) was compared at baseline and 3, 6, 9, and 12 months after administration. The mean deviation values at baseline and 12 months measured using the Humphrey visual field test (30-2 Swedish Interactive Threshold Algorithm standard) were compared. Adverse reactions and dropouts were observed.

Results

IOP significantly decreased from 15.5 ± 2.7 mmHg at baseline to 13.3 ± 2.5 mmHg after 3 months, 13.7 ± 2.3 mmHg after 6 months, 13.9 ± 2.4 mmHg after 9 months, and 13.7 ± 2.3 mmHg after 12 months (P < 0.0001). There was no significant difference in the mean deviation values at baseline (-3.66 ± 3.49 dB) and after 12 months (-3.41 ± 3.80 dB). Adverse reactions occurred in 9 patients (9.0%): conjunctival hyperemia (n = 6), eye pain (n = 1), iritis (n = 1), and blepharitis (n = 1). Twenty-one patients (21.0%) discontinued administration because of changes in medication (n = 7), interruption of visits (n = 5), adverse reactions (n = 4), and others.

Conclusions

After administering omidenepag isopropyl, the IOP in patients with NTG decreased within 1 year, visual fields were maintained, and safety was satisfactory. Omidenepag isopropyl can be used as the first-line medication for patients with NTG.
