Purpose To evaluate the efficacy and safety of the pars plana clip ( PPC ) in the Ahmed valve tube PC 7 inserted via the pars plana in patients with secondary refractory glaucoma. Methods Prospective and interventional case series that included 8 patients with secondary refractory glaucoma. The pars plana vitrectomy and the implant of the modified tube were performed during the same surgery. Control of intraocular pressure ( IOP ) and the development of intra‐ and postoperative complications were evaluated during the follow‐up. Results Follow‐up time was twelve months in all the patients. Control of IOP was achieved in 85% of patients, and 75% needed no antiglaucoma treatment. The complications that occurred were transient hypotony in two cases, choroidal detachment in two cases, and one case of intraocular hemorrhage and one case of hyphema. No case of tube extrusion was observed. Conclusions Our clinical experince suggests that implantation of the Ahmed tube modified with the PPC via the pars plana is safe and effective in patients with secondary refractory glaucomas.
