To describe the outcome of simple limbal epithelial transplantation along with Phacoemulsification and IOL implantation for visual rehabilitation in limbal stem cell deficiency due to ocular surface squamous neoplasia.
This case report of a 66-year-old woman clinically diagnosed with OSSN in her right eye involving all cornea and limbus meridians. Topical chemotherapy for tumor treatment was done, followed by SLET and sequential cataract surgery. The entire tumor could be clinically reduced with topical chemotherapy but a LSCD could not be avoided. After SLET, corneal transparency was restored, and anterior segment details could be seen, phacoemulsification was performed uneventfully. After a follow-up period of 18 months, stable ocular surface and visual acuity and no tumor recurrence was observed.
SLET is an option to restore not only corneal epithelium homeostasis but also gain cornea transparency, avoid keratoplasties and allow anterior segment surgeries to be performed.
This case report provide evidence of benefits of simple limbal epithelial transplantation in ocular surface squamous neoplasia and shows that cataract surgery could be performed uneventfully after limbal stem cell transplantation.
描述单纯角膜缘上皮移植联合超声乳化白内障吸除术及人工晶状体植入术,用于因眼表鳞状上皮肿瘤导致角膜缘干细胞缺乏的视力恢复的效果。
该病例报告为一名66岁女性,临床诊断为右眼眼表鳞状上皮肿瘤,累及整个角膜和角膜缘子午线。先进行了局部化疗以治疗肿瘤,随后进行了单纯角膜缘上皮移植术(SLET)及后续的白内障手术。局部化疗后整个肿瘤在临床上缩小,但角膜缘干细胞缺乏无法避免。单纯角膜缘上皮移植术后,角膜恢复透明,可观察到眼前节细节,超声乳化白内障吸除术顺利进行。随访18个月后,眼表稳定,视力良好,未观察到肿瘤复发。
单纯角膜缘上皮移植术不仅是恢复角膜上皮稳态的一种选择,还能恢复角膜透明性,避免角膜移植,并允许进行眼前节手术。
本病例报告提供了单纯角膜缘上皮移植术在眼表鳞状上皮肿瘤中的益处的证据,并表明角膜缘干细胞移植后白内障手术可顺利进行。
