Abstract
OBJECTIVE: To compare the efficacy and safety of the Baerveldt® glaucoma implant (BGI) between a preserved donor scleral patch alone and double scleral flaps, comprising a preserved donor scleral patch and an autologous scleral pedicle flap. METHODS: This was an open-label retrospective study. We analyzed the cases of 52 consecutive patients (56 eyes) who underwent BGI surgery with the Hoffman elbow (#BG 102-350, Abbott) and were followed up for >1 year. Twenty-one eyes underwent BGI surgery with a preserved donor scleral patch alone (donor-patch group), and the other 35 eyes underwent BGI surgery with a preserved donor scleral patch and an autologous scleral pedicle flap (double-flap group). The main outcome was the incidence of Hoffman elbow exposure associated with each surgical approach. RESULTS: Three patients in the donor-patch group (14.3%) developed Hoffman elbow exposure, whereas in the double-flap group, no cases had Hoffman elbow exposure (p = 0.048). CONCLUSIONS: The use of the double scleral flaps technique was more efficient in preventing Hoffman elbow exposure.
