摘要目的:探讨改良的翼状胬肉切除联合自体结膜和羊膜移植术及干扰素滴眼液治疗原发性翼状胬肉的临床疗效。方法:前瞻性病例对照研究。连续入选2018年6月1日至12月31日于北京同仁眼科中心进行手术治疗的原发性翼状胬肉患者，按照随机区组设计分为试验组和对照组。试验组患者行改良结膜移植联合羊膜移植术，术后给予干扰素滴眼液；对照组患者行自体结膜移植术。所有患者术前观察翼状胬肉分型及大小，记录视力、眼压及眼前节情况；术后1、2周和1、3、6、12个月对患者进行随访，观察视力、角膜上皮愈合情况以及翼状胬肉复发等情况。本文数据均为计数资料，采用卡方检验和Fisher精确检验进行统计学分析。结果:70例（77只眼）翼状胬肉患者纳入研究，其中男性30例，女性40例，年龄50~70岁。试验组35例（38只眼），对照组35例（39只眼）。术后12个月共54例（60只眼）数据完整，其中试验组28例（30只眼），对照组26例（30只眼）。两组各有1只眼的角膜上皮于术后7~14 d修复，其余患眼的角膜上皮均在术后7 d内完全修复。两组角膜上皮愈合情况分布的差异无统计学意义（ P=1.00）。两组患者术前及术后视力下降（两组各2只眼）、稳定（试验组15只眼，对照组23只眼）和提高（试验组13只眼，对照组5只眼）的眼数分布比较，差异无统计学意义（ P=0.053）；术后12个月两组患者均未出现4级结膜增生真性翼状胬肉复发，结膜纤维组织增生1、2、3级患者两组间差异无统计学意义（ P=0.405）。 结论:改良的翼状胬肉切除联合自体结膜和羊膜移植术及干扰素滴眼液治疗原发性翼状胬肉复发率低，对健康结膜组织损伤小，可为翼状胬肉的手术治疗提供新的选择。 （中华眼科杂志，2020，56：768-773）

abstractsObjective:To observe the clinical effect of modified conjunctival transplantation and amniotic membrane transplantation combined with use of interferon (IFN) alpha-2b eye drops in the treatment of primary pterygium.Methods:This was a prospective case-control study. Patients with primary pterygium were treated from June 1, 2018 to December 31, 2018 in the Department of Ophthalmology, Beijing Tongren Hospital, and they were divided into two groups (the experimental group and the control group) by the method of randomized block design. Patients in the experimental group received modified conjunctival transplantation and amniotic membrane transplantation combined with use of IFN alpha-2b eye drops, while patients in the control group received pterygium resection combined with conjunctival autograft transplantation. The pterygium type and size were observed before operation, while visual acuity, intraocular pressure and anterior segment details were recorded either. The follow-up was done at 1 week, 2 weeks, 1 month, 3 months, 6 months and 12 months after operation. The visual acuity, corneal epithelial defect, and pterygium recurrence were observed. All data in this manuscript are enumeration data, the expected frequency of pterygium type distribution in the two groups was more than 5, and the chi square test was used, fisher′s exact test was used to compare the other data between the two groups.Results:Seventy patients (77 eyes) with pterygium were in this study, including 30 males and 40 females, aged from 50-70 years old. There were 35 cases (38 eyes) in the experimental group and 35 cases (39 eyes) in the control group. 12 months after operation there were 54 cases (60 eyes) including 28 cases (30 eyes) in the experimental group and 26 cases (30 eyes) in the control group with complete data. The corneal epithelium defects of 1 eye in each group was repaired within 7-14 days after operation, and the rest eyes were completely repaired within 7 days after operation. There was no significant difference in the distribution of corneal epithelial healing between the two groups ( P= 1.00). There was no significant difference between the two groups in the number of eyes distribute with decreased visual acuity (2 eyes in each group), stable visual acuity (15 eyes in the experimental group and 23 eyes in the control group), and improved visual acuity (13 eyes in the experimental group and 5 eyes in the control group) ( P=0.053). There was no recurrence in the two groups at 12 months after surgery, and there was no significant difference between the two groups in the number of patients with conjunctival hyperplasia of grades 1, 2 and 3 ( P=0.405). Conclusions:Modified conjunctival transplantation and amniotic membrane transplantation combined with use of IFN alpha-2b eye drops got low recurrence rate for primary pterygium and less damage to the healthy conjunctival tissue. This combined treatment strategy provides a new choice for the treatment of pterygium . (Chin J Ophthalmol, 2020, 56: 768-773)
