放射性核素^(90)Sr/^(90)Y敷贴器辅助治疗翼状胬肉

Use of ^(90)Sr/^(90)Y applicator in treatment of primary pterygium

目的将单纯切除、切除加自体角膜缘干细胞移植、切除加自体角膜缘干细胞移植术后应用放射性核素90Sr/90 Y敷贴器三种治疗翳状胬肉的手术方式进行比较,寻求一种治疗翼状胬肉的理想手术方式。方法对121眼采用单纯切除(A组41眼)、切除加自体角膜缘干细胞移植(B组39眼)、切除加自体角膜缘干细胞移植术后应用放射性核素90Sr/90 Y敷贴器(C组41眼)3种方法治疗,并对治疗结果进行对比分析。结果 A组复发率为14.63%,B组复发率为15.39%,C组复发率仅为2.44%,3种手术方法均有部分病例周边角膜云翳。结论放射性核素90Sr/90 Y敷贴器辅助治疗能够明显降低翼状胬肉复发率及干眼症的发生率,是一种相对理想的手术方法。

Objective To observe the effects of pterygium excision,pterygium excision combined with bulbar conjunctival flap transplantation,pterygium excision combined with bulbar conjunctival flap transplantation and ^90Sr/^90Y applicator.Methods We treated 121 eyes with the three kinds of operation style including pterygium excision（group A）,pterygium excision combined with bulbar conjunctival flap transplantation（group B）,pterygium excision combined with bulbar conjunctival flap transplantation and ^90Sr/^90Y Applicator（group C）.Results The recurrence rate was 14.63%,15.39% and 2.44% respectively for group A,B and C.Conclusion Pterygium excision combined with bulbar conjunctival flap transplantation and ^90Sr/^90Y Applicator can effectively decrease recurrence of primary pterygium,occurrence of dry eye syndrome and is a relatively good operation style.
