Comparison of intraocular pressure changes in Japanese patients with neovascular age-related macular degeneration treated with aflibercept or faricimab.

Abstract

Purpose: To assess the short-term changes in intraocular pressure (IOP) following intravitreal injections of aflibercept or faricimab in Japanese patients with neovascular age-related macular degeneration (nAMD).

Study design: Retrospective observational study.

Methods: This retrospective observational study included 161 eyes from 160 Japanese patients diagnosed with nAMD. Of these, 127 eyes (127 patients) were treated with 2 mg/0.05 mL aflibercept, and 34 eyes (33 patients) received 6 mg/0.05 mL faricimab. Each group underwent three consecutive monthly injections. The IOP in each treated eye was measured using non-contact tonometry at each visit over a 3-month period following the initial injection.

Results: The mean baseline IOP in the aflibercept group was 14.4 ± 2.8 mmHg, decreasing to 13.2 ± 3.0 mmHg after 3 months (P < 0.001), whereas the mean baseline IOP in the faricimab group was 13.8 ± 2.1 mmHg, with a change to 13.5 ± 1.5 mmHg after 3 months (P = 0.1873).

Conclusion: The loading phase treatment with aflibercept resulted in a decrease in IOP. Faricimab showed a similar trend, there was no significant difference between the two treatments.
