Short-term Efficacy and Safety of Latanoprostene Bunod Therapy for Patients with Primary Open-angle Glaucoma

Purpose: To evaluate the short-term efficacy and safety of latanoprostene bunod 0.024% in patients with primary open-angle glaucoma.Methods: A retrospective study was conducted from September 2022 to September 2023, involving 29 eyes from patients diagnosed with primary open-angle glaucoma. The study analyzed the intraocular pressure (IOP)-lowering effects of latanoprostene bunod 0.024% at 1 and 3 months after administration. Additionally, adverse events reported by patients at each visit were documented.Results: The mean age of patients at the start of treatment was 64.46 years. The baseline IOP was 17.46 ± 4.03 mmHg, which significantly decreased to 15.07 ± 4.23 mmHg (<i>p</i> = 0.002) at 1 month (29 eyes) and 14.93 ± 3.86 mmHg (<i>p</i> = 0.002) at 3 months (28 eyes) after latanoprostene bunod administration. After 1 month, 9 patients reported adverse events, including conjunctival hyperemia (1 eye, 3.5%), itching (2 eyes, 6.9%), foreign body sensation (2 eyes, 6.9%), stinging (2 eyes, 6.9%), ocular pain (2 eyes, 6.9%), and deepening of the upper eyelid sulcus (1 eye, 3.5%). The patient who experienced deepening of the upper eyelid sulcus discontinued treatment. After 3 months, 2 eyes with itching discontinued treatment due to conjunctival allergy.Conclusions: Latanoprostene bunod 0.024% demonstrated short-term efficacy in reducing IOP and a manageable safety profile in patients with primary open-angle glaucoma.
