Purpose: To investigate the indications and outcome of human allogenic conjunctival transplantation.
Methods: The necrotic tissues and scars were removed from the fornix by using the residual conjunctiva. Then the allograft without Tenon's capsule was transplanted to cover the wound.
Results: At 6 postoperative months, the surface was completely healed in 76%x. For patients with mechanical trauma or thermal burn, the area of transplanted conjunctiva was less than one third, or using donor conjunctiva from parents or siblings are of better prognossis.
Conclusions: 1) Allogenic conjunctival transplantation is a feasible treatment for servere symblephron and lid defects. 2) The result is poor when residual conjuctiva is less than 1/2. 3) The outcome is best in mechanical trauma and worst in alkaline burns, with thermal burns somewhere in between. 4) The simple bulbal conjunctival transplantation has better results.
