不同移植术治疗翼状胬肉

目的比较新鲜人羊膜移植、保存人羊膜移植、自体带角巩膜缘干细胞的结膜瓣移植及异体角膜缘干细胞移植联合羊膜移植治疗翼状胬肉的临床疗效。方法对196例202眼翼状胬肉患者随机组合分为A、B、C、D组。A组70眼行翼状胬肉切除联合新鲜羊膜移植术;B组75眼行翼状胬肉切除联合保存人羊膜移植术;C组39眼行翼状胬肉切除联合自体带角巩膜缘干细胞的结膜瓣移植术;D组18复发性翼状胬肉不适宜提供自体角膜缘而采用异体角膜缘干细胞移植联合羊膜移植术。术后随访6-12个月,对各组术后行动态观察及疗效进行回顾性分析。结果A组70眼术后复发16眼,复发率为22.86%;B组75眼术后复发17眼,复发率为22.67%;C组39眼术后复发3眼,复发率为7.69%;D组18眼术后复发5眼,复发率为27.78%;A组与B组比较(χ2=3.33,P>0.05);A组与C组比较(χ2=4.003,P<0.05);A组与D组比较(χ2=0.18,P>0.05);B组与C组比较(χ2=6.84,P<0.05);B组与D组比较(χ2=0.21,P>0.05);C组与D组比较(χ2=3.89,P<0.05);A组与C组、B组与C组、C组与D组具有显著差异性。结论自体自体带角巩膜缘干细胞的结膜瓣移植是目前治疗翼状胬肉较理想的手术方法。而异体角膜缘干细胞移植联合羊膜移植术后胬肉复发的主要原因是免疫排斥反应。     

翼状胬肉显微切除联合丝裂霉素C加自体带角膜缘上皮结膜移植术观察

目的 探讨翼状胬肉显微手术方法,观察翼状胬肉切除联合应用丝裂霉素C(MMC)加自体带角膜缘上皮的结膜移植术治疗翼状胬肉的疗效。方法 对1251例1326只眼,在手术显微镜下剖切分离球结膜与病变组织,切除胬肉并做广泛的变性球筋膜切除,在结膜下放置0.2 mg/ml的MMC棉片,彻底冲洗后将同侧眼颞上方带有角膜缘上皮的结膜瓣移植到胬肉处的巩膜上。术后随访12～72月,平均27.5月,观察复发情况。结果 术后反应轻,移植片存活,37只眼复发,复发率为2.79％。结论 翼状胬肉显微手术切除联合应用丝裂霉素C加自体带角膜缘上皮的结膜移植术,术后复发率低,是一种安全、有效的方法。     

翼状胬肉上结膜反向移植联合羊膜移植治疗复发胬肉

目的：观察胬肉上结膜反向移植联合羊膜移植治疗复发性翼状胬肉的疗效。

方法：回顾性系列病例研究。回顾2009-01/2012-01本院确诊的复发性翼状胬肉26例26眼,均为经历一次手术,手术方法为翼状胬肉切除联合自体角膜缘干细胞移植术,复发1a以上病例。本次研究中,切除胬肉组织时,将其上结膜充分游离后切下保存,羊膜覆盖胬肉切除后裸露巩膜面,再将保留的胬肉上的结膜植片反向覆盖羊膜上缝合。术后1,2wk; 1mo及3mo观察结膜植片愈合情况、羊膜溶解吸收时间、角膜创面修复时间、角膜新生血管及胬肉复发率。术后随访12mo。

结果：结膜植片愈合时间6.03±2.76d,羊膜溶解吸收时间14.26±3.64d,角膜创面修复时间5.42±1.58d。术后3mo,胬肉切除后裸露巩膜面新生结膜及结膜植片愈合良好,无明显胬肉术后并发症。术后1a,再度复发2例,复发率8%,治愈率92%。

结论：对于复发性翼状胬肉,因传统自体角膜缘干细胞移植已经创伤部分角膜缘及眼表结膜瘢痕,单纯结膜移植,或单纯羊膜移植,术后胬肉复发率偏高,本方法取胬肉上结膜反向移植,避免大面积创伤眼表,取材容易,而且良好控制术后翼状胬肉复发问题,不失为一种解决复发性翼状胬肉的良好选择。     

Pterygium treatment using 5-FU as adjuvant treatment compared to conjunctiva autograft

BACKGROUND: The use of conjunctiva autograft, adjunct antimetabolite therapy has been shown to be effective in preventing pterygium recurrence. OBJECTIVE: To compare 5 fluorouracil (5-FU) to conjunctival autograft in the treatment of large, fleshy pterygium. METHODS: A randomised controlled prospective study of outcome of pterygium treatment using 5-FU as adjuvant treatment compared to conjunctiva autograft. Thirty-five eyes with large pterygium treated with bare sclera conjunctival excision plus 5-FU were compared with 33 eyes treated with excision and conjunctival autograft alone. RESULTS: Post-operative pterygium recurrence was observed in four (11.4%) eyes treated with 5-FU and 4 (12.1%) eyes treated with conjunctiva autograft (P>0.05). The post-operative complications included, granuloma formation 11.4% for 5-FU and 3.0% for autograft and conjunctival discharge 5.7% for 5-FU group only. CONCLUSION: 5-FU is marginally superior to conjunctival autograft in the prevention of pterygium recurrence but neither gives a more desirable single digit recurrence rate. Randomised studies combining both conjunctival autograft and 5-FU in pterygium treatment is advocated to further explore their effect.     

翼状胬肉手术中自体角膜缘干细胞移植与生物羊膜移植的对比

目的观察翼状胬肉手术中自体角膜缘干细胞移植与生物羊膜移植的效果。方法72例（84眼）翼状胬肉随机分为自体角膜缘干细胞移植组（A组）和生物羊膜移植组（B组）。术中首先进行翼状胬肉切除,之后分别进行自体角膜缘干细胞移植或生物羊膜移植。随访6～24个月。结果A组术后角膜上皮平均于（3．19±0．65）d愈合,B组术后角膜上皮平均于（6．22±1．35）d愈合,（P〈0．05）。A组术后1眼复发,复发率为2．38％,B组术后3眼复发,复发率为7．14％（P〉0．05）。结论自体角膜缘干细胞移植与生物羊膜移植均能降低翼状胬肉术后复发率,其中自体角膜缘干细胞移植更易于角膜创面愈合。     

不同术式治疗翼状胬肉的疗效分析

目的:比较巩膜暴露法、带球结膜瓣的角膜缘干细胞移植术、带球结膜瓣的角膜缘干细胞移植术联合术中封闭球结膜与Tenon囊之间间隙的手术方式治疗翼状胬肉的临床疗效。方法:翼状胬肉患者130例138眼,分为三组:A组(45例,48眼):采用巩膜暴露法行翼状胬肉切除术;B组(42例,45眼):带球结膜瓣的角膜缘干细胞移植术;C组(43例,45眼):翼状胬肉切除联合带球结膜瓣的角膜缘干细胞移植术及封闭球结膜与Tenon囊之间间隙。术后随访12mo。结果:三组复发率分别为27.1%,8.9%,4.4%。A组与其余两组比较存在显著差异(P<0.05),B组与C组存在差异,但无统计学意义。肉芽肿形成:A组3眼,B组2眼,C组未见。C组泪阜的形态及位置明显优于A组及B组。结论:带球结膜瓣的角膜缘干细胞移植术联合术中封闭球结膜与Tenon囊之间间隙能显著降低翼状胬肉术后复发率,减轻炎症反应,预防肉芽肿的形成,有助于恢复泪阜的正常形态及位置,是目前治疗翼状胬肉的较理想手术方式。     

Randomised controlled study of conjunctival autograft versus amniotic membrane graft in pterygium excision

AIM: To determine whether amniotic membrane can be used as an alternative to conjunctival autograft after pterygium excision. METHODS: 287 eyes with either primary or recurrent pterygium were included in this study. All eyes were randomised to undergo conjunctival autograft or amniotic membrane transplantation after pterygium excision by a single surgeon. 106 eyes in primary pterygium and 14 eyes in the recurrent group were treated with conjunctival autograft, and 148 eyes in primary pterygium and 19 eyes in the recurrent group were treated with amniotic membrane transplantation. Patients were followed up at 6 weeks and 6 months after operation. The main outcome measurement was recurrence rate after surgery. RESULTS: In the conjunctival group, the recurrence rate was 12.3%, 21.4% and 13.1% for primary, recurrent and all pterygia, respectively. In the amniotic membrane group, the recurrence rate was 25.0%, 52.6% and 28.1% for primary, recurrent and all pterygia, respectively. The recurrence rate for all pterygia in the amniotic membrane group was significantly higher than that in the conjunctival group (p = 0.003). CONCLUSIONS: Amniotic membrane graft had a higher recurrence rate than conjunctival autograft. However, it is an alternative choice, especially for advanced cases with bilateral heads or patients who might need glaucoma surgery later.

目的:观察角膜缘干细胞与结膜移植治疗翼状胬肉的疗效。方法:采用自体角膜缘干细胞与结膜移植术,对38例43眼初发和复发性翼状胬肉患者进行治疗,术后随访3～30月,平均10月。结果:38例43眼中34例38眼上皮愈合稳定,角膜恢复正常光滑、透明,胬肉无复发。4例5眼失访。结论:自体角膜缘上皮移植为病变区角膜和结膜提供新的干细胞来源,是治疗翼状胬肉的理想方法。眼科学报1999;15:89—90。     

角膜缘干细胞移植术治疗原发性翼状胬肉

目的：评价自体角膜缘干细胞移植治疗原发性翼状胬肉的安全性和有效性。

方法：前瞻性观察性研究。采用自体角膜缘干细胞移植术治疗鼻侧原发性翼状胬肉264例(男性142例,女性122例)。患者平均年龄54.22±15.24岁。翼状胬肉术后1、3、7d及1、3、6、9、12、36mo进行定期随访。评估手术时间,角膜上皮愈合时间,术后复发率和手术并发症。

结果：平均手术时间为25.7±2.6min。经过至少3a的术后随访,术后角膜上皮愈合时间为3.85±0.72d。14例患者出现眼科并发症。本研究未发现虹膜睫状体炎、睑球粘连、角膜溃疡等威胁视力的严重并发症。结膜移植片水肿5例,肉芽肿形成3例,结膜下血肿6例。随访3a,11例患者复发,复发率为4.17%,首次出现复发时间为3mo,平均8mo。

结论：经长期随访,自体角膜缘干细胞移植术无严重并发症,复发率低,是治疗原发性翼状胬肉安全有效的方法。我们还建议对于原发性翼状胬肉手术,12mo的术后随访为最佳时间。     

Evaluation of the recurrence rate and complications for pterygium treated with limbal conjunctival autograft

AIM: To evaluate the safety and efficacy of limbal conjunctival autograft transplantation for treating primary pterygium over a period of 3y. METHODS: Prospective observational consecutive case series. In this study, 264 eyes of 264 patients (142 males and 122 females) with nasal primary pterygium were treated using the technique of limbal conjunctival autograft. The mean ages of the patients were 54.22±15.24y. After excision of the pterygium patients were followed up on 1, 3, 7d and at 1, 3, 6, 9, 12, and 36mo. Recurrence of pterygium, complications, operation time and corneal epithelialization time were evaluated. RESULTS: The average surgery time was 25.7±2.6min. With a minimum 3-year of follow-up, postoperative corneal epithelialization was completed in 3.85±0.72d. Complications were observed in 14 cases. Vision-threating complications such as iritis, scleral thinning symblepharon or ulceration were not detected in the study. Five eyes with graft edema, 3 eyes with granuloma formation and 6 cases with a subconjunctival hematoma in the nasal conjunctiva. By the end of 3-year follow-up, recurrence was detected in 11 cases. The recurrence rate was 4.17%, and the onset of recurrence was 3mo, the average recurrence time was 8mo. CONCLUSION: There were no severe complications and few recurrences when limbal conjunctival autograft transplantation was performed after long-term follow-up, we suggest that limbal conjunctival autograft transplantation is a safe and effective technique in primary pterygium. We also recommend that 12-month follow-up is optimal on primary pterygium surgery.     

Comparison of de-epithelialized amniotic membrane transplantation and conjunctival autograft after primary pterygium excision

PURPOSE: To study the efficacy of de-epithelialized amniotic membrane (AM) graft (AmbioDry, Okto Ophtho Inc., Costa Mesa, CA, USA) as an adjunctive therapy after primary pterygium excision in comparison to standard conjunctival autograft. METHODS: A retrospective review of 23 eyes of 22 patients receiving pterygium excision followed by AM transplantation was performed. The results were compared retrospectively with 40 eyes of 36 patients receiving conjunctival autograft after pterygium excision. All patients were Hispanic. Recurrence was defined as regrowth of fibrovascular tissue over the corneoscleral limbus onto clear cornea in the area of previous pterygium excision. RESULTS: The pterygium recurrence rates after AM graft and conjunctival autograft were 35 and 25%, respectively. There was no significant difference in recurrence rate between the two groups (P=0.56). The mean follow-up period was 5.9+/-2.4 months. No major complications were noted in either group. CONCLUSION: This study provides preliminary evidence that de-epithelialized AM graft is as effective as conjunctival autograft in preventing pterygium recurrence in this Southern California Hispanic population.
