摘要
Purpose: The purpose of this study was to retrospectively evaluate whether it is possible to decrease the risk of Molteno tube erosion through the conjunctiva by using a newtechniquewhere the silicone tube is inserted into a scleral tunne l instead of being covered only by the con- junctiva. Methods: We reviewed Molteno implants carried out at theUniversity H ospital ofOulu, in 332 patientswho underwent traditionalMolteno implantation bet ween October 1986 and October 1998 and 92 patients who underwent surgery with th e new technique between November 1998 and April 2001. Results: With our former t echnique, conjunctival erosions occurred in 15 eyes of 15 patients (4.5%)-afte r a median follow-up of 3.5 months (range 1-72 months); no conjunctival compli cations were discovered in patients who underwent surgery using the new techniqu e during a median follow-up of 22 months (range 10-39 months). (p=0.038, twosa mple test of proportions). Conclusion: Inserting the Molteno tube into a scleral tunnel prevents tube extrusion through the conjunctiva in eyes with Molteno imp lants. The technique for making the scleral tunnel is described.
