目的比较二种不同术式治疗翼状胬肉对角膜上皮修复及复发率影响。方法对92例(100眼)翼状胬肉分别行显微切除联合角膜缘干细胞移植术(52例56眼)归为A组,暴露角膜缘带蒂结膜瓣转位术(40例44眼)归为B组。术后用1%荧光素钠染色法,观察角膜上皮修复速度,并随访4～22月。结果显微切除角膜缘上皮移植、暴露角膜缘带蒂结膜瓣转位术后,角膜创面上皮修复时间分别4.64±1.82、6.14±2.48,二者比较差异有显著性(P<0.05)。随访观察,角膜缘干细胞移植术有2眼(3.56%),带蒂结膜瓣转位术有9眼(20.45%)复发。结论显微切除联合角膜缘干细胞移植术治疗翼状胬肉角膜创伤小.创面修复快.复发率低。
Objective To compare the effects of two different surgical procedures on the repair and recurrence rate of corneal epithelium in patients with pterygium. Methods 92 cases (100 eyes) of pterygium were treated with micro-resection combined with limbal stem cell transplantation (52 cases, 56 eyes) were divided into group A, limbal conjunctival flap transposition (40 cases, 44 eyes) For the B group. After surgery with 1% sodium fluorescein staining to observe the corneal epithelial repair rate and follow-up 4 to 22 months. Results The microsurgical removal of limbal epithelium and corneal limbal conjunctiva flap transplanting revealed that the repair time of corneal wound epithelium was 4.64 ± 1.82 and 6.14 ± 2.48, respectively (P <0.05). Follow-up observation, limbal stem cell transplantation in 2 eyes (3.56%), pedicle conjunctival flap transposition of 9 eyes (20.45%) recurrence. Conclusions Microsurgical resection combined with limbal stem cell transplantation for the treatment of corneal trauma of the pterygium is small, the wound is repaired quickly, and the recurrence rate is low.
