Abstract
BACKGROUND: Anti-VEGF agents has been widely used in ocular diseases, but its safety for treating anterior segment disorders, the conclusions are controversial. METHODS: Several major databases, including CENTRAL, MEDLINE, and EMBASE, were searched. Safety data from 18 randomized controlled trials (RCTs) were used to compare anti-VEGF treatment in the ocular anterior segment in pterygium and neovascular glaucoma treatment with placebo/sham treatment for eye diseases. A meta-analysis for adverse events was performed. RESULTS: Eighteen RCT studies with 955 eyes were included in the meta-analysis. Significant difference in conjunctival disorders (OR: 1.62; 95% CI, 1.01-2.59; P = .05) was noted among the included studies, but not in ocular intolerance (odds ratio [OR]: 0.75; 95% CI, 0.34-1.62; P = .46), corneal disorders (OR: 0.71; 95% CI, 0.37-1.37; P = .31), or the subgroup analysis of conjunctival disorders. CONCLUSIONS: The administration of anti-VEGF agents in the ocular anterior segment for patients with pterygium and glaucoma was tolerable in tolerance and cornea, but was the risk factor of conjunctival disorders. The healing of corneal epithelium may be delayed in patients with primary corneal epithelial defects after anti-VEGF application. However, due to the limited evidence, further research should be performed on the safety of anti-VEGF administration in patients with different corneal disorders.
