Popis: Purpose: It has been reported that corneal endothelial cells (CEC) decrease faster when the tip of the Baerveldt glaucoma implant (BGI) tube is inserted into the anterior chamber than into the vitreous cavity. We investigated whether surgically relocating the tip of the BGI tube from the anterior chamber to the vitreous cavity could reduce CEC loss.Patients and Methods: The subjects were 11 consecutive patients (11 eyes) that could be followed >12 months after relocation surgery. We compared the intraocular pressure (IOP), reduction slope of CEC density and annual reduction rate of CEC density before and after relocation surgery. Results: The relocation surgery did not significantly change IOP (p=0.974). The mean preoperative and postoperative IOP were 13.1 ± 4.5 and 13.6 ± 4.3 mmHg. The reduction ratio of the CEC density was 15.4 ± 6.7 cells/mm2/year before relocation surgery and significantly slower at 8.3 ± 6.5 cells/mm2/year after relocation surgery (p=0.024). Two patients resulted in bullous keratopathy after relocation surgery.Conclusions: Relocating the tip of BGI tube from the anterior chamber to the vitreous cavity could reduce CEC loss.
