Abstract
AIM: To evaluate the effect of limbal stem cell autograft transplantation combined with mitomycin C in the treatment of pterygium.
METHODS: Totally 258 cases 272 eyes patients of newly developed pterygium (229 eyes) and recurrent pterygium (43 eyes) were performed limbal stem cell autograft transplantation combined with mitomycin C. The postoperative followup period ranged from 12 to 24 months.
RESULTS: Fourteen eyes of newly developed pterygium and 3 eyes of recurrent pterygium (6.3%) were recurred.
CONCLUSION: The method of limbal stem cell autograft transplantation combined with mitomycin C drops can reduce the recurernce rate.

翼状胬肉是眼科的常见病,是结膜组织变性所致的一种良性增生性病变,原因不明,可能与风沙、烟尘、阳光、紫外线等长期刺激有关,多发生于室外工作者[1]。翼状胬肉的治疗方法主要是手术,资料显示,单纯胬肉切除术后容易复发,复发率可高达30%~69%,随着眼科显微手术的发展,翼状胬肉手术复发率大为降低[2,3],我科200601/200906采用自体角膜缘干细胞移植联合应用丝裂霉素治疗翼状胬肉共258例272眼,取得满意效果,现报告如下。
1对象和方法
1.1对象
自200601/200906我科门诊进行翼状胬肉手术258例272眼,其中男136例140眼,女122例132眼;年龄37~68(平均53.4)岁;初发性胬肉229眼,复发性胬肉43眼(其中伴有睑球粘连6眼)。术后随访12~24mo。
1.2方法
所有病例均在显微镜下进行,术眼爱尔凯因滴眼液表面麻醉,20g/L利多卡因局部浸润麻醉,自胬肉头部起切除胬肉,深度达角膜前弹力层,分离胬肉颈部、体部至半月皱襞并切除胬肉,注意不要损伤内直肌鞘膜和肌腹。暴露出巩膜面,形成植床,复发性胬肉应将巩膜面瘢痕组织彻底切除。将浸有0.2mg/mL丝裂霉素棉片放置于巩膜暴露区3~4min,取出后用生理盐水250mL彻底冲洗。取术眼颞上方带角膜缘干细胞的结膜移植片,即自结膜缘向内切0.5~1.0mm宽薄层角膜缘组织,植片大小与巩膜暴露区大小相一致。将植片上皮面朝上平铺于裸露的巩膜植床上,角膜缘组织侧与植床角膜缘相吻合,用100尼龙线将植片与球结膜残端经浅层巩膜间断缝合,保证植片平展和贴附,取材区创面不作处理。术毕结膜囊涂典必殊眼膏,包扎术眼。术后局部点用典必殊滴眼液、金因舒滴眼液滴眼各5次/d,口服抗生素。裂隙灯下检查结膜和角膜创面愈合、植片生长,有无感染、角膜新生血管、复发、并发症,10d拆线。典必殊滴眼液点眼次数逐渐减少,持续1mo左右,监测眼压。
2结果
术后早期患者均有不同程度的结膜及植片的水肿、异物感、畏光、流泪现象,一般在3d后症状明显减轻,角膜上皮长入,植片水肿逐渐消退。2~3wk左右结膜、植片充血水肿消退,角膜恢复透明。所有病例植片均成活。术前胬肉组织遮盖或部分遮盖瞳孔区患者术后视力明显提高,其余患者视力无明显改善。术后所有病例随访12~24mo,14眼初发性胬肉分别于术后8~14mo复发,3眼复发性胬肉于术后5mo时复发,复发率6.3%。
