PURPOSE: To describe an unusual series of complications after glaucoma filtering surgeries with their clinical findings and outcome after tailored non-conventional modes of therapy. PATIENTS AND METHODS: Eighteen patients who underwent re-interventions (medical or surgical) after glaucoma filtering surgeries during the period at two tertiary centers, excluding those that required conventional modes of treatment (medical control or re-trabeculectomy, simple wound closure for traumatic wound dehiscence, bleb revision or needling, laser iridotomy), were included...

REVIEW
Nathan M Kerr, Jing Wang, Keith Barton
Recently many new devices and procedures have been developed to lower intraocular pressure in a less invasive and purportedly safer manner than traditional glaucoma surgery. These new devices might encourage an earlier transition to surgery and reduce the long term commitment to topical glaucoma medications with their associated compliance and intolerance issues. While often seen as an adjunct to cataract surgery, a growing body of evidence suggests that primary MIGS may be a viable initial treatment option...

This report is of two cases of asymmetrical papilloedema in patients with asymmetrical intraocular pressures (IOPs). The first patient presented with headaches, transient visual obscurations (TVOs), and elevated IOPs, and was found to have increased intracranial pressure caused by a torcula meningioma. He developed papilloedema after his IOPs were pharmacologically lowered; the papilloedema resolved after the IOP became elevated again after stopping his glaucoma drops, and then again returned as the IOP reduced when the drops were restarted...

PURPOSE: The aim of this study was to assess bleb function using Wuerzburg bleb classification score (WBCS) for bleb morphology on slit lamp, intraocular pressure (IOP), and gonioscopy. METHODS: A total of randomly selected 30 eyes posttrabeculectomy were assessed for bleb function with the trio of bleb morphology, IOP, and gonioscopy. Bleb was assessed using the WBCS of 0-12 on slit lamp, IOP was assessed using applanation tonometry, and visualization of inner ostium and iridectomy were assessed using gonioscopy...

PURPOSE: To assess the safety and efficacy of ultrasound coagulation of the ciliary body in refractory glaucoma. METHODS: This prospective multicenter interventional study was conducted in two Italian university-affiliated glaucoma centers: St. Orsola-Malpighi Teaching Hospital (Bologna, Italy) and University Eye Clinic of Genoa (Genoa, Italy). The main inclusion criterion was the diagnosis of glaucoma with a baseline intraocular pressure (IOP) ≥ 21 mmHg while on maximum topical and systemic medical hypotensive treatment...

PURPOSE OF REVIEW: The present article reviews the clinical features and pathogenesis of pigment dispersion syndrome and pigmentary glaucoma and provides an update regarding their diagnosis and management. RECENT FINDINGS: Newer imaging modalities including ultrasound biomicroscopy and anterior segment optical coherence tomography facilitate visualization of the iris concavity characteristic of eyes with pigment dispersion syndrome and pigmentary glaucoma. Patients with pigmentary glaucoma may be distinguished from those with other glaucoma types by the presence of typical symptoms, personality type, and patterns of diurnal intraocular pressure fluctuation...

BACKGROUND: Glaucoma comprises a group of neurodegenerative diseases resulting in retinal ganglion cell death within the optic nerve head. It is projected to affect almost 80 million people worldwide by 2020. The condition's asymptomatic nature translates to over half of glaucoma sufferers being unaware of their condition. By the time of diagnosis, irreversible blindness is likely to have occurred. Prime areas of glaucoma research therefore include identification and optimization of risk factors for the disease, accurate and early diagnostic tools and novel therapeutic methods...

PURPOSE: To evaluate outcomes of Descemet membrane endothelial keratoplasty (DMEK) in eyes with previous trabeculectomy or a drainage device. METHODS: This is a retrospective study of 108 consecutive DMEK performed between October 2013 and December 2015. All eyes were divided into 3 groups: surgical treatment (ST) group, medical treatment (MT) group, and control group. Visual improvement, endothelial cell loss, and postoperative complications, including rejection, graft failure, and intraocular pressure elevation (≥25 mm Hg) were evaluated...

PURPOSE: To evaluate the results of anti-VGEF with trabeculectomy in the treatment of neovascular glaucoma, a severe complication of retinal vein occlusion (RVO). PATIENTS AND METHODS: This is a prospective case series of consecutive patients with neovascular glaucoma secondary to retinal vein occlusion. All patients underwent panretinal photocoagulation and a mean of 3 anti-VEGF injections prior to trabeculectomy. Ophthalmic parameters were recorded pre- and postoperatively: visual acuity (VA), intraocular pressure (IOP), iris examination, gonioscopy and fundus examination, and as necessary, fluorescein angiography...

PURPOSE: To compare the intraocular pressure (IOP) response after the water drinking test (WDT) in patients who have undergone trabeculectomy or tube shunt surgery. METHODS: This prospective study examined 40 eyes of 34 open-angle glaucoma subjects who had undergone trabeculectomy (n=20) or tube shunt surgery (n=20). Both groups were matched by IOP range and by number of topical antiglaucoma medications used. After a baseline IOP assessment, subjects drank 10 mL water per kg body weight over 15 minutes...

PURPOSE OF REVIEW: The purpose of this review is to update the clinician on the recent work in the field of pediatric glaucoma. RECENT FINDINGS: Using the iCare tonometer to measure intraocular pressure (IOP) in children is highly successful. New data from the Infant Aphakia Treatment Study show that after 5 years of follow-up the risk of developing glaucoma is similar between patients that receive initial intraocular lens implantation and those who are left aphakic...

PURPOSE: To report the prevalence, type, and cause of diplopia in medically and surgically treated patients with glaucoma. DESIGN: Cohort study. PARTICIPANTS: A total of 195 adult patients with glaucoma treated in a glaucoma referral practice. METHODS: A total of 195 adult patients with glaucoma who had undergone surgical or medical management were prospectively enrolled. Forty-seven patients had undergone glaucoma drainage device (GDD) surgery (Baerveldt 350, Baerveldt 250 [Abbott Medical Optics, Abbott Park, IL], or Ahmed FP7 [New World Medical Inc, Rancho Cucamonga, CA]), 61 patients had undergone trabeculectomy, and 87 patients were medically treated...

AIM: To evaluate the results of Ahmed glaucoma valve (AGV) in eyes with a failed trabeculectomy. MATERIALS AND METHODS: This retrospective study evaluated 61 eyes with a failed trabeculectomy that underwent implantation of an AGV due to uncontrolled intraocular pressure (IOP) on maximal medical therapy. Success was defined as IOP ≤ 21 mm Hg (criterion 1) or 20% reduction in IOP (criterion 2) with or without antiglaucoma medications. Persistent hypotony, loss of light perception, and reoperation for IOP control were defined as failure...

PURPOSE: Aim of this study was to compare outcome of four different surgical modalities for management of persistent glaucoma after silicone oil removal in vitrectomized eyes. METHODS: This is a prospective comparative study, carried out on a cohort of 41 eyes (41 patients). Patients were randomly allocated to Group A (trabeculectomy), Group B (deep sclerectomy), Group C (Ahmed valve), or Group D (Ex-Press Minishunt). Postoperatively, all patients were followed regularly at 1 day, 1 week, 1, 3, and 6 months, and 1 year for intraocular pressure evaluation...
