Purpose . To investigate alternative surgical method to cover subconjunctival portion of the tube in tube shunt surgery in glaucoma Methods. In thirteen eyes of twelve patients who underwent tube shunt surgery at WEH between July 1991 to November 1996 a "rotating" autologous scleral lamellar graft was created to cover the subconjuctival course of the tube. These patients were followed for clinical signs of conjuctival breakdown, graft melt, tube erosion, anterior staphylomas, graft related inflammation, infections or graft related complications. Results. The patients were followed up for a mean of 16 5 months( range 1-60 months). All eyes tolerated the autologous graft well without any clinical evidence of tube erosions, graft melting , graft related or intraocular inflammation Conclusions The use of autologous sciera, to cover the tube in a tube shunt procedure appears to be effective and without inappropriate short term risk. It offers the advantages of availability , lower cost, and eliminates the potential risk of transmission of infectious disease( i.e. slow-virus, HIV etc.).
