To evaluate the consecutive treatment results regarding pterygium recurrence and the efficacy of exclusive strontium-/yttrium-90 beta-irradiation for primary and recurrent pterygia and to analyze the functional outcome.
Between October 1974 and December 2005, 58 primary and 21 recurrent pterygia were exclusively treated with strontium-/yttrium-90 beta-irradiation with doses ranging from 3,600 to 5,500 cGy. The follow-up time was 46.6 +/- 26.7 months, with a median of 46.5 months.
The treatment led to a size reduction in all pterygia (p < 0.0001). Neither recurrences nor side effects were observed during therapy and follow-up in this study. Best-corrected visual acuity increased (p = 0.0064). Corneal astigmatism was reduced in recurrent pterygia (p = 0.009).
Exclusive strontium-/yttrium-90 beta-irradiation of pterygia is a very efficient and well-tolerated treatment, with remarkable aesthetic and rehabilitative results in comparison to conventional treatments, especially for recurrent lesions which have undergone prior surgical excision.
评估翼状胬肉复发的连续治疗结果以及锶 - /钇 - 90β射线单独照射治疗原发性和复发性翼状胬肉的疗效，并分析功能结局。
1974年10月至2005年12月期间，58例原发性翼状胬肉和21例复发性翼状胬肉接受了剂量范围为3600至5500厘戈瑞的锶 - /钇 - 90β射线单独照射。随访时间为46.6±26.7个月，中位数为46.5个月。
治疗使所有翼状胬肉的大小减小（p < 0.0001）。在本研究的治疗和随访期间，未观察到复发或副作用。最佳矫正视力提高（p = 0.0064）。复发性翼状胬肉的角膜散光减少（p = 0.009）。
翼状胬肉的锶 - /钇 - 90β射线单独照射是一种非常有效且耐受性良好的治疗方法，与传统治疗相比，具有显著的美学和康复效果，特别是对于先前已接受手术切除的复发性病变。
