Clinical Efficacy of Omidenepag Isopropyl for Primary Open-Angle Glaucoma, Normal Tension Glaucoma, or Ocular Hypertension: A Meta-Analysis.

Purpose: To investigate the clinical efficacy of omidenepag isopropyl (OMDI) among glaucoma patients in terms of increased intraocular pressure (IOP) changes through a meta-analysis.

Methods

Studies investigating the clinical efficacy of OMDI toward glaucoma patients were systemically searched. Inclusion criteria include recruiting studies that consisted of glaucoma or normal tension glaucoma patients who received OMDI treatment at least 4 weeks in duration. The primary outcome was to compare changes in IOP levels at baseline before OMDI treatment and after OMDI treatment.

Results

Six studies were included with a total of 358 eyes. Our results showed OMDI monotherapy resulted in significant decreased IOP among patients with ocular hypertension, with weighted mean difference post-OMDI treatment being -4.684 (95% confidence interval: -6.010 to -3.358) and I2 of 91.092%. Separate subgroup analyses also showed initial IOP greater than 21 mmHg and those within the age group greater than 65 years old to be correlated with significant reduction in IOP post-OMDI. Randomized control trial (RCTs) design was also found to be superior compared with non-RCT in terms of investigating IOP changes after OMDI. The country of origin of the recruited studies and OMDI dosage frequencies were also found to have no effect on overall IOP changes after OMDI treatment.

Conclusions

The current meta-analysis indicates OMDI to be a clinically effective treatment for glaucoma patients in terms of lowering IOP levels.
