目的:评估翼状胬肉切除术后90Srβ射线敷贴的疗效及安全性,分析翼状胬肉复发的相关因素。方法:2006-05/2008-09翼状胬肉患者79名93眼行切除术后90Srβ射线敷贴治疗。计算翼状胬肉复发率,同时比较男性与女性,年龄<40岁与≥40岁,原发性及复发性翼状胬肉在治疗后的复发率。结果:翼状胬肉复发7眼。<40岁及既往手术或其他治疗后复发性翼状胬肉患者复发率较高。翼状胬肉术后90Srβ射线敷贴治疗后并发症少见,包括轻微的结膜炎、术后疼痛、畏光、流泪等,但未发现严重的长期并发症,特别是无巩膜坏死及放射性白内障的发生。结论:翼状胬肉术后90Srβ射线敷贴治疗安全、有效,能降低翼状胬肉的复发率,且无严重并发症出现。年龄及复发性翼状胬肉可能影响治疗结果。
Objective: To evaluate the efficacy and safety of 90Srβ-ray application after pterygium resection and to analyze the related factors of recurrence of pterygium. Methods: 79 patients (93 eyes) with pterygium from May 2006 to September 2008 were treated with 90Srβ ray. Calculate the recurrence rate of pterygium, while men and women, age <40 years old and ≥ 40 years old, the recurrence rate of primary and recurrent pterygium after treatment. Results: Pterygium recurrence in 7 eyes. Patients <40 years of age and previous surgery or other recurrent pterygium recurrence rate is higher. Pterygium surgery 90Srβ ray application of complications after treatment is rare, including mild conjunctivitis, postoperative pain, photophobia, tearing, but did not find serious long-term complications, especially non-scleral necrosis and radiation cataract . CONCLUSIONS: 90Srβ-ray application of pterygium surgery is safe and effective and can reduce the recurrence rate of pterygium without serious complications. Age and recurrent pterygium may affect treatment outcome.
