Amniotic membrane with living related corneal limbal/conjunctival allograft for ocular surface reconstruction in Stevens Johnson syndrome

Objective: 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.Design: Prospective, noncomparative, interventional case series.Patients and Methods: Ten eyes of 10 patients with total limbal stem cell and conjunctival deficiency secondary to Stevens-Johnson syndrome under-went excision of cicatricial tissue followed by amniotic membrane and living related corneal limbal/conjunctival transplantation.Main Outcome Measures: 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.Results: 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%).Conclusions: Ammotic 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.Universidade Federal de São Paulo, Dept Ophthalmol, Paulista Sch Med, São Paulo, BrazilUniversidade Federal de São Paulo, Dept Ophthalmol, Paulista Sch Med, São Paulo, BrazilWeb of Scienc
