Efficacy and Safety of Corticosteroid Implants in Non-infectious Uveitis: A Systematic Review with Network Meta-analysis

To compare different existent implants for noninfectious uveitis. We performed a systematic review of randomized clinical trials (RCTs), searching in five electronic databases and screening reference lists of included studies and relevant reviews. We performed network meta-analysis to compare 0.18 mg fluocinolone acetonide implants, 0.70 mg and 0.35 mg dexamethasone implants, and sham procedures. Eight RCTs were included in this systematic review, of which three articles from two studies (n = 358 patients) were included in network meta-analysis. The 0.70 mg dexamethasone implant (at 1.5 months) was associated with better results than the 0.18 mg fluocinolone acetonide implant (at 1 month) at improving vitreous haze grading (RR = 2.96; 95%CI = 1.23–7.07), and with less frequently development of cataracts at 12 (RR = 0.36; 95%CI = 0.17; 0.79) and 36 months (RR = 0.37; 95%CI = 0.20; 0.71). In the short term, the 0.70 mg dexamethasone implant is superior at improving vitreous haze, and shows lower risk of cataracts. However, additional RCTs with standardized outcomes are needed.
