方法:对我院2006-01/2010-12行不同手术方式治疗的164例206眼翼状胬肉患者的临床资料进行回顾性分析。A组(36例50眼)采用单纯切除术; B组(41例47眼)采用单纯切除联合丝裂霉素术; C组(42例52眼)采用胬肉切除联合丝裂霉素和羊膜移植术; D组(45例57眼)采用胬肉切除联合自体角膜缘干细胞移植术。记录每例手术时间,术后1wk; 3,6,12,24mo进行随访观察,观察结膜愈合及胬肉复发情况等。
结果:A组复发率最高,B组复发率有所降低,C、D 组复发率较A组及B组明显降低,C、D 组复发率无明显差异。手术时间方面,单纯切除组的手术时间明显短于其他组,羊膜移植及自体角膜缘干细胞移植组的手术时间较长。复发主要发生在术后1a内。
结论:丝裂霉素可以降低单纯胬肉切除术的复发率,角膜缘干细胞移植及羊膜移植术可以更有效的降低胬肉的复发率。 相似文献

不同术式治疗翼状胬肉的疗效观察 总被引:2,自引:0,他引:2
0引言原发性翼状胬肉是一种原因仍不很清楚的眼科常见病和多发病之一。传统的单纯胬肉切除,手术快捷,但术后复发率较高,一般为30%~50%,甚至高达69%[1]。近年来,随着角膜缘干细胞理论的提出和人们对羊膜功能认识的深入,手术方法得以不断改进,方法较多。我们对照观察分别采用单纯胬肉切除,羊膜移植,自体角膜缘干细胞移植3种不同术式治疗翼状胬肉的术后疗效,并报告如下。1对象和方法1.1对象所有患者63例63眼均系2006-12/2008-12在我院眼科治疗患者。其中,单纯胬肉切除组25例25眼,羊膜移植术组20例20眼,自体角膜缘干细胞移植术组18例18眼。年龄45~68(平均57.5)岁。1.2方 相似文献

Purpose
To investigate and compare the efficacy of conjunctival autograft and conjunctival transpositional flap for the treatment of primary pterygium surgery.Design
Retrospective, interventional case series analysis.Materials and methods
Medical records of 48 patients who underwent pterygium surgery by conjunctival autograft or conjunctival transpositional graft for primary pterygium surgery were reviewed. The conjunctival defects after pterygium excision were repaired in 21 eyes with conjunctival autograft and in 27 eyes with conjunctival transpositional flaps. All operations were performed under subconjunctival anesthesia using 8.0 vicryl sutures. Two groups were compared in terms of pterygium size, surgery time, complications and pterygium recurrence.Results
Mean pterygium size was 2.8?mm in conjunctival transpositional flap group, and 3.4?mm in conjunctival autograft group (p?<?0.01). Mean surgery time in conjunctival transpositional flap and conjunctival autograft groups was 15.9 and 21.7?min, respectively. The haematoma formation under the graft was observed postoperatively in one eye of conjunctival autograft group. The only one case of recurrence was observed in both conjunctival autograft and conjunctival transpositional flap groups (3.7% and 4.7%, respectively). Mean follow up time was 11.78?months in conjunctival transpositional flap group and 14.95?months in conjunctival autografting group (p?<?0.01).Conclusion
Both conjunctival transpositional flap and conjunctival autograft techniques have same results in terms of pterygium recurrence and surgery complications in the treatment of primary pterygium. Surgery time in conjunctival transpositional flap technique is significantly shorter. Conjunctival transpositional flap technique may be a good alternative method for primary pteryg?um surgery. 相似文献14.
目的 对比观察两种治疗翼状胬肉的手术效果.方法 翼状胬肉患者123例124只眼,随机分为A组,(60只眼),行翼状胬肉切除联合准分子激光治疗性角膜切削术(PTK);B组,(64只眼),行翼状胬肉切除联合自体角膜缘干细胞移植术.比较其复发率、术后角膜修复情况、手术前后泪膜恢复及散光和矫正视力提高情况.结果 术后复发率两组差异无统计学意义,A组患者术后早期角膜修复情况、泪膜破裂时间的提高优于B组(P<0.01).矫正视力的提高及散光减少在早期二者差异无统计学意义,晚期A组略高于B组(P<0.05).结论 单纯胬肉切除联合准分子激光治疗性角膜切削术优于胬肉切除联合自体角膜缘干细胞移植术.Abstract: Objective To explore a safe and simple method ofpterygium surgery to reduce recurrence rate and side effect.Methods All 123 patients (124 eyes) were randomly divided into two groups:PTK surgery group (group A,60 eyes) and corneal limbal stem cells autograft transplantation surgery group (group B,64 eyes),then compared the recurrence rate,satisfaction rate,reparation of cornea,and tear function,astigmatism,beast corrected visual acuity (BCVA) before and after surgery.Results The recurrence rate of two groups was similar.There were statistically significant different of the reparation of cornea and tear function (BUT) after surgery in early days,P <0.001.No significant difference was found in eyesight raise and astigmatism decrease in early stage,but in later stage group A were raised compared group B,P <0.05.Conclusions Pterygium excision surgery with phototherapeutic keratectomy is a method which can achieve good effect and decrease surgery complication maximality. 相似文献

Purpose
Primary pterygium is a fibrovascular proliferation over the nasal cornea, probably resulting from the limbal stem cell deficiency. Intraoperative mitomycin-C application seems to associate with reduced recurrences, however produced ocular surface problems and vision threatening complications. The present clinical study investigated the safety profile of autologous limbal conjunctival transplantation in terms of recurrence rate, as the main outcome measure and complications as the secondary outcome.Methods
The present study was randomised, interventional and prospective clinical study conducted from a tertiary Hospital. Pterygium excision was performed with limbal conjunctival autograft availed from the affected eye. Secondary pterygia resulting from inflammation, trauma and other diseases were excluded. Patients were followed up for 18 months for recurrence and other complications. Microsoft Office Excel 2007 was used for statistical analysis.Results
A total of 71 eyes of sixty-eight patients with primary pterygia included between November 2007 and October 2010. The study recruited 35 (51%) males and 33 (49%) females with mean age of 36.9 with ±12.82 years standard deviation (mean, SD) ranging from 19 to 75 years. Age grouped by range intervals categorised into six groups. Pterygium was diagnosed in 32 (45%) right eyes and 39 (55%) left eyes. There were 65 (91.55%) nasal and 4 (5.63%) temporal pterygium and no case of double head pterygia found. Average horizontal extension of the pterygium measured was 1.67 mm (±4.23) from the apex to the corneal limbus. Graft oedema in 1 (0.71%) patient, graft bleed in 2 (1.42%) cases and 1 (0.72%) case of granuloma observed. No recurrences encountered during 18 months follow up.Conclusions
Pterygium occurred predominantly in the younger population group 36.9 mm (±12.82) probably due to the increased outdoor activity with high exposure to sunlight and dusty atmosphere. Absence of recurrences was probably attributable to the smaller pterygium size of 1.67 mm (±4.23), use of the autologous limbal conjunctival graft and treatable intra and post operative complications successfully. 相似文献16.
Epithelial ingrowth is a rare but devastating condition of the eye, known to complicate incisional ocular procedures. We report
a case of secondary glaucoma due to epithelial ingrowth following limbal conjunctival autograft in a case of recurrent pterygium.
To prevent such devastating conditions from occurring dissection of recurrent pterygium demands special care to avoid anterior
chamber penetration.

Purpose
To compare and evaluate the safety and efficacy of two surgical techniques for the management of primary pterygium.Design
Prospective randomized clinical trial using the CONSORT 2010 Statement (Consolidated Standards of Reporting Trials) for parallel group randomized trials.Setting
Department of Ophthalmology, Al-Minya University, Faculty of Medicine, Egypt.Methods
The study included 150 eyes of 150 patients with primary pterygium. The mean age was 49 ± 12 years (range 24–74 years). Simple excision under local anesthesia was performed followed by closure of the bare sclera by suture less and glue free conjunctival autograft in 50 eyes of 50 patients (group 1), versus the conventional method of a sutured conjunctival autograft in 100 eyes of 100 patients (group 2).Results
The pterygium recurrence rate was 6% for group 1, 8% for group 2.Graft dehiscence occurred in 4 eyes out of 50 (8%) in group 1. Graft retraction occurred in 6 (12%) out of 50 eyes for group 1 versus 6 eyes (6%) in group 2. Pyogenic granuloma occurred in 3 (3%) eyes out of 100 in group 2. No other serious complications were noted. At the 3 week visit the overall patient satisfaction score was statistically significantly higher for group 1 (P < 0.002) compared to group 2. At 3 months postoperatively, the gain in uncorrected visual acuity (UCVA) ranged from 0.2 to 0.5 Log MAR in 10 eyes.Conclusion
Sutureless and glue free conjunctival autograft technique is easy, safe, effective, prevents potential adverse reactions encountered with the use of foreign materials. This technique has an acceptable pterygium recurrence rate that is comparable to conventional sutured conjunctival autograft for primary pterygium. 相似文献20.
