Surgical technique, perioperative management and early outcome data of the PAUL® glaucoma drainage device

Background: Step by step surgical technique for closure of dehisced conjunctiva in a patient with glaucoma drainage device (GDD). Purpose: To describe a step by step new surgical technique using combined tutoplast, conjunctival autograft and amniotic membrane to close dehisced conjunctiva in a patient with GDD. Case report: Patient with previous history of herpetic kerato uveitis and Baerveldt tube developed dehiscence of conjunctiva over the plate. He had previous surgical interventions on two occasions, which consisted of direct closure of the conjunctiva and conjunctival autograft, with no success. In order to close the persistent defect, he underwent additional surgery in the form of relieving conjunctival incisions, tutoplast, conjunctival autograft and amniotic membrane to ensure closure of defect and healing. Conclusions: Tube/plate erosions are a very challenging problem to manage, especially in eyes that have undergone several surgical interventions. As demonstrated here, tutoplast, conjunctival autograft and amniotic membrane can be used in conjunction, in situations where conjunctival scarring otherwise preclude successful repair.

Abstract Purpose The purpose of this study is to report the safety and efficacy of pars plana glaucoma drainage devices with pars plana vitrectomy using one of the vitrectomy sclerotomy sites for tube placement in patients with refractory glaucoma. Methods Retrospective case series of 28 eyes of 28 patients who underwent combined pars plana glaucoma drainage device and pars plana vitrectomy between November 2016 and September 2019 at Massachusetts Eye and Ear. Main outcome measures were intraocular pressure (IOP), glaucoma medication burden, best corrected visual acuity, and complications. Statistical tests were performed with R and included Kaplan-Meier analyses, Wilcoxon paired signed-rank tests, and Fisher tests. Results Mean IOP decreased from 22.8 mmHg to 11.8 mmHg at 1.5 years (p = 0.002), and mean medication burden decreased from 4.3 to 2.1 at 1.5 years (p = 0.004). Both IOP and medication burden were significantly lower at all follow-up time points. The probability of achieving 5 < IOP ≤ 18 mmHg with at least 20% IOP reduction from preoperative levels was 86.4% at 1 year and 59.8% at 1.5 years. At their last visit, three eyes (10.7%) achieved complete success with IOP reduction as above without medications, and 14 eyes (50.0%) achieved qualified success with medications. Hypotony was observed in 1 eye (3.6%) prior to 3 months postoperatively and 0 eyes after 3 months. Visual acuity was unchanged or improved in 23 eyes (82.1%) at their last follow-up. Two patients had a visual acuity decrease of > 2 lines. Two eyes required subsequent pars plana vitrectomies for tube obstruction, and one eye had transient hypotony. Conclusions The results of pars plana glaucoma drainage device and pars plana vitrectomy using one of the vitrectomy sclerotomy sites for tube placement are promising, resulting in significant IOP and medication-burden reductions through postoperative year 1.5 without additional risk of postoperative complications. Inserting glaucoma drainage devices into an existing vitrectomy sclerotomy site may potentially save surgical time by obviating the need to create another sclerotomy for tube placement and suture one of the vitrectomy ports.

Abstract OPEN-DOOR EXPANSILE laminoplasty is a practical surgical technique for the treatment of cervical myelopathy secondary to cervical spinal stenosis. Laminoplasty procedures were first described in the late 1970s and have undergone numerous modifications. The current article reviews the indications, techniques, and outcome data for cervical laminoplasty. Complications of laminoplasty and comparison to laminectomy outcomes are also discussed.
