Purpose: To examine the effectiveness and safety of Baerveldt glaucoma implants in eyes with refractory glaucoma following vitrectomy. Methods: We performed a retrospective study of a non-comparative case series of 30 eyes of 30 patients who had undergone the implantation of a Baerveldt glaucoma device. All eyes (30/30) had a minimum follow-up of 6 months, and 16/30 (53%) had a follow-up of 24 months. Surgical success was defined as intraocular pressure (IOP) < 22 mmHg on the last two follow-up visits with or without glaucoma medication and a decrease in IOP of at least 20% compared to preoperative values with or without glaucoma medication. Results: The mean IOP before implantation of a Baerveldt glaucoma device was 30 mmHg [(plus or minus) 11.4 mmHg standard deviation (SD)] with maximally tolerated medical therapy. Six months after implantation of the Baerveldt glaucoma device, the mean IOP was 17.3 mmHg ((plus or minus) 6.7 mmHg SD) and the mean number of glaucoma medications had gone down from 3.0 ((plus or minus) 0.4 SD) to 0.3 ((plus or minus) 0.3 SD). Successful outcomes were found in 24 eyes (80%). Small complications occurred in six eyes (20%): transient postoperative hypotony (17%) and tube retraction (3%). Larger complications occurred in another six eyes (20%): corneal decompensation requiring keratoplasty (7%), suprachoroidal haemorrhage (3%) and persistently high IOP (10%). Conclusion: Baerveldt glaucoma devices are a valid treatment option in eyes with refractory glaucoma after vitreous surgery, although failure occurred in 20% of our patients. Transient complications occurred in 20% and severe complications in another 20%.
