作者在切除翼状胬肉的同时采用刮除相应角膜缘旁的一窄条表层巩膜组织的方法,对2000多个病例作了翼状胬肉切除术。切除区留下5×5mm左右的巩膜暴露区,用6-0黑丝线将结膜切缘固定在巩膜上。术毕立即用锶~(90)放疗。延迟放射会使胬肉的复发率升高。一般来说放疗的锶~(90)照射器应跨越在角巩缘,使角膜缘及其两侧同时得到治疗。对肥厚而多血管的胬肉,应将照射器放在治疗区与直肌附着点之间。锶~(90)的最大剂量不超过3000REPS(物理伦琴当量),否则就有可能导致白内障。但剂量太小又不足以抑制新生血管。新生血管在术后24小时
The authors removed the pterygium at the same time by scraping the corresponding corneal edge of a narrow strip of surface scleral tissue method, more than 2000 cases of pterygium was performed. Excision zone left about 5 × 5mm scleral exposure area, with 6-0 black silk will be fixed in the sclera margin of the conjunctiva. Surgery immediately with strontium ~ (90) radiotherapy. Delayed radiation will make the recurrence rate of pterygium increased. In general, the strontium ~ (90) irradiator radiotherapy should be across the corner of the limbus, the limbus and both sides of the same treatment. For hypertrophy and vascular polyp, the illuminator should be placed between the treatment area and the rectus muscle attachment point. Strontium ~ (90) maximum dose does not exceed 3000REPS (physical Roentgen equivalent), otherwise it may lead to cataracts. But the dose is too small and not enough to inhibit neovascularization. Neovascularization 24 hours after surgery
