Eduardo Pimentel, Jimena Schmidt
INTRODUCTION: Trabeculectomy is considered the standard for glaucoma surgery. Postoperative scarring is one the factors associated with surgery failure. Different antimetabolites have been used in order to reduce this risk, particularly 5-fluorouracil and mitomycin C. Although both are considered effective, it is not clear if they are different in terms of success of trabeculectomy and adverse effects. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others...

INTRODUCTION: We present a case of persistent aqueous misdirection post Ahmed glaucoma valve despite undergoing an anterior vitrectomy with hyaloido-zonulectomy, and iridectomy. CASE REPORT: A 73 year old female 4 months post phaco-trabeculectomy was referred with persistent high IOP. Post-operatively, she developed aqueous misdirection with a flat anterior chamber (AC) but with an IOP of 15▒mm Hg. On presentation her AC was shallow with peripheral iris-cornea touch and IOP was 39▒mm Hg...

PURPOSE OF REVIEW: Two new translimbal glaucoma devices (Xen Gel Stent and InnFocus MicroShunt) have been developed with the goal of optimizing the predictability and safety for subconjunctival glaucoma surgery. RECENT FINDINGS: The new subconjunctival glaucoma implants are manufactured from nonsilicone, biocompatible materials, which may reduce the postoperative inflammatory and fibrotic reactions that can lead to failure. Early data suggests a favorable safety profile with significant reductions in intraocular pressure (IOP)...

PURPOSE: Phacoemulsification has been cited as a possible cause of bleb failure in eyes with prior trabeculectomy. No method has been developed to directly evaluate the risk of bleb failure after phacoemulsification. We investigate the use of trypan blue during cataract surgery in the setting of a pre-existing trabeculectomy to evaluate the functional status of the bleb and predict post-operative bleb function. PATIENTS AND METHODS: 14 patients contributing one eye each with a history of prior trabeculectomy with mitomycin C undergoing phacoemulsification with intraocular lens implantation were enrolled in this prospective, nonrandomized clinical trial...

This case study reports the successful implantation of the Xen ab interno gel stent in a 44-year-old male with refractory chronic open angle glaucoma. The patient had multiple unsuccessful filtration surgeries including a trabeculectomy and two Ahmed glaucoma valves placed superotemporally and inferonasally OD. The patients intraocular pressure was reduced from 29▒mm Hg preoperatively to 17▒mm Hg 1 year after surgery, without any ocular complications. The Xen gel stent may be considered as a possible intervention to lower IOP in patients with refractory glaucoma, despite previous filtration surgeries if the superonasal conjunctiva is spared and healthy...

PURPOSE: This study investigates the possible role of the filtration bleb in the continuous decrease in corneal endothelial cell (CEC) density observed following trabeculectomy. METHODS: This study involved 51 eyes of 37 glaucoma patients who underwent trabeculectomy. The CEC density was determined by contact specular microscopy in three areas: (1) the cornea center, (2) near the trabeculectomy filtration bleb, and (3) the opposite side of the bleb. The eyes were grouped according to post-surgical follow-up years: 0-1 (Group 1), 1-2 (Group 2), 2-3 (Group 3), 3-4, (Group 4), and 4+ years (Group 5)...

Background: Chronic retinal necrosis (CRN) is a rare chronic granular necrotizing retinitis that was first described in 2013. CRN is characterized by intraocular inflammation accompanied by occlusive vasculitis, granular retinitis, and slowly progressing necrosis around the retina in a host with partial immune dysfunction. Cytomegalovirus (CMV) is reported to be a causative agent. There are several ocular complications such as retinal detachment and neovascular glaucoma; however, there has been no description of a clinical manifestation of neovascular glaucoma in CRN...

AIM: To present a novel scleral flap suturing technique for filtering glaucoma surgery in order to control high postoperative intraocular pressure (IOP). METHODS: Description of 'the accordion suture' technique for mitomycin C augmented trabeculectomy. In cases of postoperative high IOP, pulling the loop of the suture helps to lift up the scleral flap by an even pressure on both edges. By means of this technique, the scleral flap opens up in an "accordion" manner, thus preventing flap obstruction and providing adequate aqueous flow...
