PURPOSE: To describe the patient outcomes and factors affecting those outcomes after aqueous shunt exposure repair. PATIENTS AND METHODS: Forty-three eyes from Robert Cizik Eye Clinic and Bascom Palmer Eye Institute from 1995 to 2007 suffered from aqueous shunt exposure and were repaired by participating surgeons. Thirty-three were tube exposures and 7 were plate exposures. The remaining 3 exposure classified complications included a patch graft exposure, an elbow exposure, and 1 unknown complication. Forty eyes were followed for evidence of additional aqueous shunt exposures or additional surgical interventions for 46.6 weeks (40.2 wk) (range: 3 to 168 wk). RESULTS: Seventeen of 40 eyes required additional surgical intervention: 15 (45%) from the tube exposure group and 2 (29%) from the plate exposure group. Five (13%) eyes needed eventual removal of the shunt. Black race, diabetes mellitus, a high number of glaucoma medications before shunt implantation, a history of multiple glaucoma laser procedures, and combination of an initial aqueous shunt implantation with another surgery were found to be associated with a worse outcome after exposure repair. CONCLUSIONS: Intraocular pressure, number of medications, and visual acuity remained stable during follow-up after revision. Diabetes mellitus was associated with a shorter average time between initial repair and reintervention, and 4 other variables were associated with a higher likelihood of reintervention.
