A modifted technique for placement of a glaucoma silicone tube in the ciliary sulcus is demonstrated. Anterior chamber placement risks corneal decompensation, and sulcus placement can be complicated by blind steps in the surgical technique. We used a 23-gauge needle ab-interno exiting the sclera 2mm from the limbus. This is docked with a 27-gauge needle, then into the barrel of a Healon GV syringe. The silicone tube then ftts snugly over the Healon syringe and can be pulled back into the sulcus with greater vector precision, thus avoiding iris or zonular damage.
