Popis: | Objective To study the efficacy of subconjunctival 5-fluorouracil (5-FU) and triamcinolone injection in halting the progression of impending recurrent pterygium. Design Randomized, prospective, controlled clinical trial. Participants One hundred nine patients who had undergone pterygium excision within the previous 6 months and developed grade 3 characteristics (impending recurrent pterygium). Methods A total of 109 eyes with impending recurrent pterygium were stratified randomly into 3 groups by treatment: 35 eyes served as the control group, 39 eyes received a 5-mg intralesional injection of 5-FU weekly for 2 weeks, and 35 eyes received one 20-mg intralesional injection of triamcinolone. All groups received 1% prednisolone acetate eye drops 4 times daily for 8 weeks. Main Outcome Measures Recurrence rate, success rate, and survival analysis were compared among the groups. Results With a mean follow-up time of 10.9±5.5 months (range, 6–26 months), the success rates of the 5-fluorouracil and triamcinolone groups were higher than the control group (87.2%, 71.4%, and 48.6%, respectively). 5-fluorouracil was significantly ( P = 0.001) more effective in inhibiting the recurrence of pterygium compared with the control group at all time points during follow-up. Kaplan–Meier survival analysis showed that the recurrence-free period of pterygium in the 5-FU group was significantly ( P = 0.005) longer than that of the control group but not in the triamcinolone group compared with the controls ( P = 0.063). There was no significant difference between the 5-FU group and the triamcinolone group ( P = 0.362). Minimal reversible complications such as steroid-induced glaucoma and superficial punctate epitheliopathy developed during the study. Conclusions Intralesional injection of 5-FU and triamcinolone was more effective in inhibiting the recurrence of pterygium than topical steroid alone, with the results in the 5-FU group reaching statistical significance. |
