To evaluate the safety and efficacy of a novel approach to implant Ex-Press Minishunt via the pars plana under a scleral flap in pseudophakic or aphakic, vitrectomized patients with secondary refractory glaucoma.
A prospective and interventional case series. Three patients presenting to Kasr Al Ainy Hospital, Cairo University with secondary glaucoma after pars plana vitrectomy. Intraocular pressure (IOP) was not controlled by silicone oil removal, if the patient was siliconized, nor the maximum medical treatment. Ex-Press Minishunt via the pars plana was implanted. We evaluated control of IOP and the development of intraoperative and postoperative complications.
During the follow up period of 6 months, control of IOP was achieved; 14, 15, and 15 mmHg at the third month, and 15, 15, and 16 mmHg at sixth month in our 3 cases without antiglaucoma treatment. Blebs were posterior and diffuse. No complications were encountered intraoperatively or postoperatively. Ultrasound Biomicroscopy (UBM) showed suprachoroidal posterior lake of fluid as an additional filtration route.
Implantation of Ex-Press Minishunt via the pars plana in aphakic or pseudophakic, vitrectomized eyes is a promising, safe and effective technique in patients with secondary glaucoma.
