目的 :探讨90 Srβ射线照射预防翼状胬肉术后复发的方法、效果、机理。方法 :追踪观察了96例 1 0 3只眼翼状胬肉术后予以90 Srβ射线照射翼状胬肉复发的情况 ,其中原发性者 94只眼 ,复发性者9只眼 ;观察时间从 8个月到 1 3年 ,平均 6年 8个月。结果 :1 0 3只眼中共 4只眼复发 ,复发率为 3 9%。其中原发性、复发性各 2只眼 ,复发率原发性者仅为 2 1 % ,而复发性者却高达 2 2 2 %。结论 :翼状胬肉术后早期 ,小量、多次照射 β射线不但大大降低了翼状胬肉的复发率 ,而且远期无重大并发症。但这一切是建立在第一次完美的手术基础上。
Objective: To explore the method, effect and mechanism of 90 Srβ irradiation in preventing postoperative recurrence of pterygium. Methods: A total of 96 cases (103 eyes) of pterygium irradiated by 90 Srβ ray were retrospectively studied, including 94 cases of primary and 9 cases of recurrent. The observation time ranged from 8 Month to 13 years, an average of 6 years and 8 months. Results: The recurrence rate was 39% in 4 eyes of 103 eyes. The primary and recurrent 2 eyes each had a relapse rate of 21% and a relapse rate of 22%. Conclusion: Pterygium surgery early, small, multiple exposure to beta rays not only greatly reduce the recurrence rate of pterygium, but no major complications in the long term. But all this is based on the first perfect surgery.
