Purpose: To assess and compare the long-term postoperative outcomes of trabeculectomy (TE), phacotrabeculectomy (PTE), and viscocanalostomy (VC) and to correlate postoperative intraocular pressure (IOP) with visual outcome. Patients and methods: This retrospective cohort observational study included 520 eyes which underwent TE with mitomycin C (MMC) (n=205), PTE with MMC (n=189), and VC ± combined cataract surgery and MMC (n=126) to control IOP between June 2010 and June 2014 by a single surgeon...

PURPOSE: To determine the medium-term outcomes for patients with advanced glaucoma undergoing viscocanalostomy. METHODS: All patients with advanced glaucoma (mean deviation (MD) - 12.00 dB or above) and patients with poor visual acuity secondary to advanced glaucoma which precluded formal visual field assessment undergoing viscocanalostomy (VC) and phaco-viscocanalostomy between 2010 and 2014 under the care of a single surgical team were included. Intraocular pressure (IOP), visual acuity (VA) and visual field outcomes were assessed from data prospectively collected into a surgical outcome database...

BACKGROUND: The objective of this study was to evaluate the efficacy of Viscocanalostomy/Phacoviscocanalostomy (VC/PVC) in lowering intraocular pressure (IOP) in Normal Tension Glaucoma (NTG) patients. METHODS: Retrospective electronic database review of patients who underwent VC/PVC for NTG between December 2009 and November 2011 at Stanley eye unit in Abergele Hospital. Goldmann applanation tonometry (GAT) was used for all IOP measurements which were taken at the time of listing for surgery and at 1 day, 1 week, 1 month, then 3-monthly up to 1 year, then half-yearly up to 3 years post operatively...

AIM: To evaluate the long-term outcome of viscocanalostomy combined with trabeculotomy and mitomycin C in the treatment of primary congenital glaucoma. METHODS: This is a retrospective study. Forty-two eyes of 26 patients with primary congenital glaucoma were enrolled. Intraocular pressure (IOP), corneal diameter (mm) and cup/disc (C/D) were measured before and after the surgery respectively. Follow-up period was 30mo. RESULTS: The mean preoperative IOP was 30...

Intracorneal hematoma or hemorrhagic descemet detachment is a rare phenomenon. It has been previously described after nonpenetrating glaucoma surgeries such as canaloplasty, viscocanalostomy, and deep sclerectomy. In this report, we describe a rare case of intracorneal hematoma as a yet nondocumented complication after Ahmed glaucoma valve implant surgery.

REVIEW
Matthias C Grieshaber
Ab externo Schlemm's canal (SC) surgery (e.g., viscocanalostomy and canaloplasty) is a valuable alternative to glaucoma filtration surgery. It targets the abnormally high resistance to outflow in the trabecular meshwork (TM) and reestablishes the physiologic outflow system. In viscocanalostomy, viscoelastic substance is injected to dilate SC, which in turn leads to microdisruptions of the inner wall. In canaloplasty, the additional intracanalicular stent (suture or Stegmann Canal Expander®) keeps the canal patent and enhances the circumferential flow...

INTRODUCTION: The purpose of this study was to compare the efficacy and safety of canaloplasty versus viscocanalostomy in management of uncontrolled primary open angle glaucoma (POAG) with medication. METHODS: Canaloplasty surgery was applied for thirty eyes of thirty patients (45-55 years) with a mean age of 48 years (Group A) and viscocanalostomy surgery was applied also for thirty eyes of thirty patients (43-54 years) with a mean age of 46 years (group B). All patients were with uncontrolled primary open angle glaucoma by maximally tolerated medical therapy...

PURPOSE: To compare the results of conventional 1064 nm neodymium-doped yttrium-aluminum garnet laser goniopuncture (Nd:YAG-GP) and selective 532 nm Nd:YAG laser (selective laser trabeculoplasty [SLT])  gonioreconditioning (GR) on trabeculo-Descemet's membrane in eyes resistant to viscocanalostomy surgery. METHODS: Thirty-eight eyes of 35 patients who underwent laser procedure after successful viscocanalostomy surgery were included in the study. When postoperative intraocular pressure (IOP) was above the individual target, the eyes were scheduled for laser procedure...

African descent is a well-documented risk factor for glaucoma development, progression, and medical and surgical failure. We reviewed the literature for evidence of outcomes disparities between Black and White populations after trabeculectomy, Ex-PRESS shunt, viscocanalostomy, canaloplasy, tube shunt, laser trabeculoplasty, and cyclophotocoagulation. There are reports of decreased surgical success in Black patients after trabeculectomy, Ex-PRESS shunt, tube-shunt, and canaloplasty. At this time, there is no strong evidence that any procedure is more effective for intraocular pressure control than standard trabeculectomy for Black patients...

Childhood glaucoma is known to be one of the most challenging conditions to manage. Surgical management is more complicated than in adults because of differences in anatomy from adults along with variations in anatomy caused by congenital and developmental anomalies, wide-ranging pathogenetic mechanisms, a more aggressive healing response, and a less predictable postoperative course. Challenges in postoperative examination and management in less cooperative children and the longer life expectancies preempting the need for future surgeries and reinterventions are also contributing factors...

We describe the case of an 18-year-old female patient who presented with vasodilation of the episcleral vessels in both eyes. The dilated vessels were more prominent in the right eye and, furthermore, examination of the fundus oculi showed a glaucomatous excavation of the right optic disc. No underlying eye or systemic disease was found as the cause for the vasodilation, therefore, Radius-Maumenee syndrome (idiopathic dilated episcleral vessels with secondary open angle glaucoma) was diagnosed. Radius-Maumenee syndrome is a diagnosis by exclusion...

REVIEW
Gábor Holló, Andreas Katsanos, Anastasios Gp Konstas
Exfoliative glaucoma is the most common type of secondary open-angle glaucoma worldwide. It is characterized by high intraocular pressure (IOP) and worse 24-hour IOP characteristics. In order to minimize progression, treatment of exfoliative glaucoma has to provide a low long-term mean IOP and good 24-hour IOP control. To achieve these goals, fixed-dose combination eye drops, argon and selective laser trabeculoplasty, and various forms of surgery (trabeculectomy, deep sclerectomy, viscocanalostomy, ab interno trabeculotomy, trabecular aspiration, and cataract surgery) all need to be considered during the long-term management of the disease...

BACKGROUND: Primary congenital glaucoma (PCG) manifests within the first few years of a child's life and is not associated with any other systemic or ocular abnormalities. PCG results in considerable morbidity even in developed countries. Several surgical techniques for treating this condition, and lowering the intraocular pressure (IOP) associated with it, have been described. OBJECTIVES: To compare the effectiveness and safety of different surgical techniques for PCG...
