Aim: To report the clinical outcome of a surgical technique for insertion of the silicone tube of the Baerveldt glaucoma implant (BGI) in the ciliary sulcus.
Methods: Non comparative, interventional case series. Eight eyes of 8 patients with a follow-up of at least 18 months who underwent insertion of BGI with the silicone tube placed in the ciliary sulcus between 1998 and 2005 were included. Control of intraocular pressure (IOP), number of pressure lowering medications, visual acuity, and surgical complications were recorded.
Results: Eight eyes of 8 patients with an average age of 76.4 years (range, 62 - 94 years) were included in the study. The IOP was reduced from a preoperative mean ± S.D.) of 27.3 ± 14.5 mmHg to 12.6 mmHg ± 5.8mmHg at 18 months. The mean number of preoperative medications for IOP control was reduced from 2.6 ± 1.8 to 1.6 ± 1.4 medications in the same period. No complications were observed during surgery or follow-up.
Conclusion: Placement of the silicone tube in the ciliary sulcus is a safe and effective alternative technique for IOP control in pseudophakic patients that could potentially reduce the likelihood of corneal endothelial loss and avoid the need for pars plana vitrectomy and posterior segment tube insertion.
