The subjects comprised 22 men and 32 women, and the mean age of the subjects was 55.0 ± 14.1 years. The mean deviation value using the Humphrey visual field test program (30– 2 SITA Standard) was − 5.03 ± 3.38 dB. The following data were retrieved from the medical records and used for retrospective analyses: IOP at baseline 1– 2 months and 3– 4 months after administration. The frequency of non-responder patients who had less than 10% IOP reduction was evaluated. Patients were observed for adverse reactions and dropouts at each time point.Results: IOP at baseline, after 1– 2 months and after 3– 4 months was 15.7 ± 2.6 mmHg, 13.5 ± 2.3 mmHg, and 13.6 ± 2.4 mmHg, respectively. There was a significant decrease in IOP after administration (p< 0.0001). Eleven patients (22.4%) were non-responders. Adverse reactions occurred in 4 patients (7.4%), including conjunctival hyperemia in 3 patients (after 1 week, 2 weeks, and 1 month, respectively) and eye pain in 1 patient (after 1 month). Five patients (9.3%) dropped out of the study because of an adverse reaction in 3 patients, insufficient IOP reduction in 1 patient, and discontinuation of follow-up of 1 patient at our institution.Conclusion: After administration of omidenepag isopropyl, IOP in patients with NTG was significantly decreased. However, adverse reactions occurred in 7.4% of patients.Keywords: intraocular pressure, adverse reactions, EP2 receptor agonist, conjunctival hyperemia |
