Interventional case report. A 7 year old girl with conge nital glaucoma and a preexisting Molteno’s drainage implant developed anterior nongranulomatous uveitis 4 months following cataract surgery. P. acnes endophtha lmitis was diagnosed by polymerase chain reaction, Southern blot, and electron m icroscopy. Extraction of the Moltenos implant was required to control the pers istent intraocular inflammation and to convert the results of polymerase chain r eaction and Southern blot testing of aqueous sample for P. acnes from positive t o negative. P. acnes may be sequestered in glaucoma implants, potentially requir ing implant removal to treat cases of P. acnes endophthalmitis.展开更多

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.展开更多
