To report the use of preserved amniotic membrane and living related corneal limbal/conjunctival transplantation in total limbal stem cell and conjunctival deficiency secondary to severe Stevens-Johnson syndrome.
Prospective, noncomparative, interventional case series.
Ten eyes of 10 patients with total limbal stem cell and conjunctival deficiency secondary to Stevens-Johnson syndrome underwent excision of cicatricial tissue followed by amniotic membrane and living related corneal limbal/conjunctival transplantation.
Reconstruction of corneal epithelium (clear appearance without epithelial defect, normal fluorescein permeability, and the absence of conjunctiva-derived goblet cells on impression cytologic testing), decrease in corneal vascularization, and improvement in visual acuity.
During a mean follow-up of 16.7 months, satisfactory ocular surface reconstruction was obtained in 2 eyes (20%), with reduced inflammation and vascularization and a mean epithelialization time of 3 weeks. Surgical failure was observed in 4 cases (40%) and complications (infection) in 4 cases (40%). Visual acuity improved in 4 eyes (40%), remained stable in 5 eyes (50%), and decreased in 1 eye (10%).
Amniotic membrane and living related corneal limbal/conjunctival transplantation were successful in 20% of severe cases of total limbal stem cell and conjunctival deficiency secondary to Stevens-Johnson syndrome. A high proportion of postoperative complications, in particular, infection, seemed to jeopardize a favorable outcome.
报告保存的羊膜及活体亲属角膜缘/结膜移植术在严重史蒂文斯-约翰逊综合征继发的全角膜缘干细胞和结膜缺损中的应用。
前瞻性、非对照、干预性病例系列。
10例史蒂文斯-约翰逊综合征继发全角膜缘干细胞和结膜缺损患者的10只眼,先行瘢痕组织切除,然后进行羊膜及活体亲属角膜缘/结膜移植。
角膜上皮重建(外观清晰无上皮缺损、荧光素通透性正常、印片细胞学检查无结膜来源的杯状细胞)、角膜新生血管减少及视力改善。
平均随访16.7个月,2只眼(20%)获得满意的眼表重建,炎症和新生血管减少,平均上皮化时间为3周。4例(40%)观察到手术失败,4例(40%)出现并发症(感染)。4只眼(40%)视力提高,5只眼(50%)视力稳定,1只眼(10%)视力下降。
羊膜及活体亲属角膜缘/结膜移植术在20%的严重史蒂文斯-约翰逊综合征继发全角膜缘干细胞和结膜缺损病例中取得成功。术后并发症比例较高,尤其是感染,似乎会影响良好的预后。
