Cypass Supraciliary Stent in Eye With Chronic Angle Closure and Postvitrectomy With Silicone Oil.

PURPOSE: To report a case of successful intraocular pressure (IOP) reduction following Cypass supraciliary stent implantation in a postvitrectomized eye filled with silicone oil and chronic angle-closure glaucoma.

MATERIALS AND METHODS: This is a case report.

RESULTS: A 19-year-old female with chronic angle-closure glaucoma underwent combined cataract extraction, goniosynechiolysis and Cypass supraciliary shunt implantation. Patient had a history of proliferative diabetic retinopathy and a tractional retinal detachment, which required pars plana vitretomy and silicone oil implantation, and was subsequently complicated by neovascular glaucoma requiring implantation of an inferior glaucoma drainage device. Approximately 6 months later, the patient's IOP increased to 36 mm Hg on maximum tolerable medical therapy. The patient underwent combined cataract extraction and Cypass implantation and is now controlled with an IOP of 16 mm Hg on 3 classes of medications 6 months postoperatively.

CONCLUSIONS: Implantation of a Cypass supraciliary shunt can be an effective means for controlling IOP in patients with chronic angle-closure glaucoma in a postvitrectomized eye with silicone oil implantation and failed glaucoma drainage device.
