Transplantation of autologous cultivated conjunctival epithelium for the restoration of defects in the ocular surface.
Ocular surface disorders are often characterised by partial or complete loss of corneo-conjunctival epithelium, which causes dramatic functional and cosmetic problems. Depletion of stem cells and the scarcity of donor tissue available make large or bilateral defects challenging to reconstruct, and usually require the transplantation of heterotopic or allogeneic grafts. We investigated the feasibility of restoring severely damaged ocular surfaces with autologous cultivated conjunctival epithelium. Conjunctival cells were harvested from the healthy eyelid bed of four patients with oculopalpebral diseases. An epithelial sheet reproducing the original conjunctival epithelium was generated by serial cell culture. This was transplanted for the first time ever to our knowledge on to the ocular surface of the same patients. Take was excellent and the cultivated epithelium was stable, resulting in great improvement of patient's symptoms and cosmesis. Transplantation of cultivated conjunctival cells opens new perspectives in the treatment of severe ocular surface disorders.
