Abstract | BACKGROUND: METHODS: We conducted a systematic review to identify randomized controlled trials of patients with primary or recurrent pterygium who received anti-fibrotic, anti- VEGF medication, or radiotherapy as adjuvants in combination with surgical procedure. The surgical procedure contained bare sclera technique or petrygium excision combination with tissue grafting. The primary outcome of this study was recurrence. Direct-comparison and Bayesian network meta-analyses were performed to assess direct and indirect evidence of efficacy. RESULTS: We obtained data from 34 randomized controlled trials, representing a total of 2483 patients. Adjuvants included bevacizumab, 5-FU (5-fluorouracil), MMC ( mitomycin C), and β-RT (beta- radiotherapy). Compared with placebo, we found distinguishable improvement in recurrence with bevacizumab (odds ratio [OR] 0.38, 95% confidence interval [CI] 0.18-0.80), MMC (0.12, 95% CI 0.06-0.21), and β-RT (0.17, 95% CI 0.04-0.69), but not with 5-FU (0.41, 95% CI 0.12-1.39). MMC significantly reduced recurrence when compared to bevacizumab (0.31, 95% CI 0.13-0.77) and 5-FU (0.28, 95% CI 0.08-0.99). The probability of having the most recurrences after excision was lowest for MMC, followed by bevacizumab and β-RT. Similar results were found in subgroup analyses, including for primary pterygium, and the patients receiving bare sclera technique or conjunctival autograft. CONCLUSIONS: Adjuvants such as MMC, bevacizumab, and β-RT could effectively prevent recurrence following pterygium excision. However, their efficacy and acceptability require further clarification in future randomized controlled trials.
