Sumario: | INTRODUCTION AND IMPORTANCE: This report describes the management of bilateral limbal stem cell deficiency (LSCD) in vernal keratoconjunctivitis (VKC) with allogeneic simple limbal epithelial transplantation (allo-SLET). PRESENTATION OF CASE: A 22-year-old female presented with bilateral VKC with total LSCD. A thick fibrotic pannus was present in both eyes, with visual axis involvement in the right eye. The central cornea in the left eye was clear. The patient underwent a cadaveric allo-SLET in the right eye to restore the ocular surface. Systemic immunosuppression with oral cyclosporine was administered following the surgery. The corrected visual acuity with scleral contact lenses (SCL) was 20/20 in both eyes which was maintained until the last follow-up visit, one year after the surgery. No recurrence of LSCD was observed in the right eye and the ocular surface was well epithelialized. DISCUSSION: Allo-SLET is a simple and efficacious surgical technique for bilateral LSCD. Eyes with VKC have a wet ocular surface, relatively clear corneal stroma, and minimal adnexal involvement. Thus, allo-SLET is the ideal procedure to address LSCD in such cases. The systemic immunosuppression that is given for ensuring graft survival can also help control the underlying allergy. Scleral contact lenses improve the visual acuity and their long-term usage does not affect the functioning of the SLET transplants. CONCLUSION: VKC with bilateral LSCD can be successfully managed with allogeneic SLET. Post-operative systemic immunosuppressants are essential to maintain viable grafts. The use of SCL can improve vision and they do not pose any risk to the SLET transplants. |
