Abstract

Abstract : Purpose: To systematically evaluate the safety and efficacy of latanoprost monotherapy for the treatment of patients with angle-closure glaucoma. Methods: We searched EMBASE, Medline, Cochrane Library, Chinese Journal Full-text Database (CNKI), Chinese Science and Technology Periodical Database (VIP), and Wang Fang using the search terms "latanoprost" (or its commercial name, Xalatan) and "angle-closure glaucoma." Resulting articles were then screened using preset inclusion criteria. Subgroup and sensitivity analyses were performed to evaluate the impact of research population, research type (blinded or controlled), and withdrawal/loss to follow-up. Results: A total of 17 studies (n=807) were included in this meta-analysis. The primary outcome measure was intraocular pressure (IOP). Changes in the mean, peak, and trough IOP from baseline were used as effect measures. As I 2 statistic revealed statistical heterogeneity, the random-effects model was applied. With the exception of 2 non-Asian populations from Australia and Peru, all 13 countries included in this study were from Asia. Latanoprost reduced mean IOP by 7.9 mm Hg (32.4%), peak IOP by 7.4 mm Hg (29.8%), and trough IOP by 7.9 mm Hg (32.5%). The most frequent ocular adverse effects were ocular hyperemia, discomfort (including eye irritation, ocular discomfort, foreign body sensation, and itching), and blurred vision with a total incidence rate of 9.4%, 8.7%, and 5.2%, respectively. Systemic adverse effects encompass rhinitis, dizziness, headache, and nonspecific skin pigmentation. Conclusions: Latanoprost is effective at reducing the IOP of patients with angle-closure glaucoma. Adverse reactions associated with latanoprost were mainly ocular in nature.
