BACKGROUND: Aim of this study is the presentation of long-term results regarding the effectiveness and safety of the implantation of Ahmed glaucoma valve (AGV) devices using a pars plana approach after vitrectomy in the treatment of therapy refractive glaucoma.
METHODS: The implantation of AGV devices using a pars plana approach after vitrectomy was performed in 27 eyes of 22 patients with neovascular glaucoma (n = 7 patients), uveitis (n = 6), complex juvenile secondary glaucoma (n = 4), primary open angle glaucoma (n = 3), pseudoexfoliation glaucoma (n = 1) and nanophthalmus (n = 1). Intraocular pressure, visual acuity and subsequent complications were documented. The mean follow-up period was 23.6 months.
RESULTS: Intraocular pressure was significantly reduced from 30.2 mmHg preoperatively to 13 mmHg after a follow-up of 36 months. The mean visual acuity did not change significantly, five eyes required a subsequent explantation of which three were due to AGV-related complications.
CONCLUSIONS: The implantation of AGV devices using a pars plana approach permits an effective and permanent reduction of intraocular pressure (IOP) even in severe therapy refractive secondary glaucoma; however, the risk of serious sight-threatening complications has to be taken into account.
