Exfoliation syndrome (XFS) is an age-related disease involving the deposition of aggregated fibrillar material (XFM) at extracellular matrices in tissues that synthesize elastic fibers. Its main morbidity is in the eye, where XFM accumulations form on the surface of the ciliary body, iris and lens. Exfoliation glaucoma (XFG) occurs in a high proportion of persons with XFS and can be a rapidly progressing disease. Worldwide, XFG accounts for about 25% of open-angle glaucoma cases. XFS and XFG show a sharp age-dependence, similarly to the many age-related diseases classified as aggregopathies...

PURPOSE: Surgically induced astigmatism (SIA) has attracted much interest in recent times because changes in corneal astigmatism can lead to decreased uncorrected visual acuity and patient discomfort. This study aimed to evaluate SIA and to identify factors correlated therewith after trabeculectomy. METHODS: We retrospectively reviewed medical charts of patients who were treated with trabeculectomy at 120° meridian (superotemporal area on right eye and superonasal area on left eye) by the same surgeon...

AIM: The objective of this study was to evaluate the efficacy and safety of bevacizumab combined with antimetabolite as an adjunctive therapy in primary trabeculectomy for glaucoma. MATERIALS AND METHODS: PubMed, Cochrane Library, and EMBASE were searched for relevant randomized controlled trials. Efficacy was evaluated by the postoperative mean intraocular pressure (IOP), complete success, and qualified success rates. Safety was evaluated by postoperative complications and surgical interventions...

OBJECTIVES: To define the safety profile of trainee trabeculectomy surgery in the United Kingdom. Surgical exposure for trainees in England is limited due to service requirements, the European working time directive constraints and increasing sub-specialisation of glaucoma surgery. Limited knowledge exists on the outcomes of supervised glaucoma surgery. The aim is to determine the safety of supervised trabeculectomy surgery performed by trainee ophthalmologists. METHODS: Retrospective case note review of all patients that had trabeculectomy surgery with MMC by consultant and trainee surgeons across multiple UK centres...

PURPOSE: To present a unique case of decompression retinochoroidopathy presenting with intraretinal, subretinal and preretinal hemorrhages. METHODS: A 65-year-old hypertensive female presented with diminution of vision in right eye of 1-week duration. She had been a known case of primary open-angle glaucoma and had undergone trabeculectomy with mitomycin C in right eye 1 week back. Her day 1 postoperative intraocular pressure was 6 mmHg. Her left eye had undergone Ahmed glaucoma valve surgery for the same 2 years back...

Objective: To investigate the patterns of surgical treatment for patients with glaucoma in the Eye Hospital of Wenzhou Medical University from 2005 to 2014. Methods: Retrospective case series about 6 781 glaucoma patients (7 751 eyes) who received surgical treatment from January 1, 2005 to December 31, 2014 in the Eye Hospital of Wenzhou Medical University. Among them, 2 869 were males and 3 912 were females, aged (62±14) years. The data of patients' demographic information, diagnosis and surgical procedures [trabeculectomy, aqueous shunts of ExPRESS and Ahmed for extraocular reservoir, cataract extraction with intraocular lens (IOL) implantation, and combined operations for glaucoma and cataract] were collected and the patterns of surgical treatment were evaluated...

PURPOSE: To determine whether anterior-segment optical coherence tomography (AS-OCT) can be used to predict post-trabeculectomy bleb outcomes. MATERIALS AND METHODS: We divided 58 eyes of 47 trabeculectomy patients into success or failure groups based on their status at 12 months after surgery. We then compared various AS-OCT measurement parameters between the two groups at 1 and 2 weeks and 1, 3, 6, and 12 months. We also analyzed the early post-trabeculectomy bleb parameters with multiple logistic regression, stepwise multiple regression, and the receiver operating characteristic (ROC) curve, to evaluate the power of these parameters to predict long-term outcomes...

BACKGROUND: This study aimed to study the long-term surgical outcomes of combined trabeculotomy-trabeculectomy (CTT) using the modified Safer Surgery System in treating childhood glaucoma at a tertiary medical center in Taiwan. METHODS: Retrospective, consecutive, noncomparative case series. We retrospectively reviewed medical records of 42 pediatric patients (age 0-18 years) who had CTT performed on their 65 eyes using the modified Safer Surgery System. The study period spanned 18 years (from January 1, 1997, to December 31, 2014)...

AIM: To conduct a systematic review and quantitative Meta-analysis of the efficacy and safety of combined surgery for the eyes with coexisting cataract and open angle glaucoma. METHODS: We performed a systematic search of the related literature in the Cochrane Library, PubMed, EMBASE, Web of Science databases, CNKI, CBM and Wan Fang databases, with no limitations on language or publication date. The primary efficacy estimate was identified by weighted mean difference of the percentage of intraocular pressure reduction (IOPR%) from baseline to end-point, the percentage of number of glaucoma medications reduction from pre- to post-operation, and the secondary efficacy evaluations were performed by odds ratio (OR) and 95% confidence interval (CI) for complete and qualified success rate...

AIM: To compare the efficacy and safety of collagen matrix implant [Ologen (OLO) implant] versus mitomycin C (MMC) with subscleral trabeculectomy (SST) for the surgical treatment of congenital glaucoma (CG) in Sturge-Weber Syndrome (SWS). METHODS: A prospective comparative randomized study of 20 eyes of 16 patients with CG associated with SWS was divided into two groups. The first group (MMC Group) included 10 eyes that were subjected to SST with MMC. The second group (OLO Group) included 10 eyes that were subjected to trabeculectomy with a collagen matrix implant (OLO implant)...

Purpose: Descemet's stripping automated endothelial keratoplasty (DSAEK) is more difficult in hypotonic eyes with filtering bleb, due to the difficulties in elevating the intraocular pressure (IOP). We report a new method that uses ophthalmic viscoelastic devices (OVDs) to achieve good graft adhesion. Case Presentation: We performed modified DSAEK surgery on 2 eyes of 2 patients, who had previously undergone a trabeculectomy. Both eyes had functioning filtering blebs; the IOP was lower than 10 mmHg without medication...

PURPOSE: We report the occurrence of an extensive submacular hemorrhage after trabeculectomy with mitomycin C in a patient with an occult choroidal neovascular membrane (CNVM). PATIENTS AND METHODS: The 66-year-old male patient had a 3 year history of primary open angle glaucoma in the left eye, which had been treated with topical antiglaucoma medication. The patient had age-related macular degeneration with an occult CNVM, for which he had received five intravitreal injections of ranibizumab and five intravitreal injections of bevacizumab in the left eye over a 3 year period...

Purpose: Glaucoma is a progressive optic neuropathy and a leading cause of blindness. Neural losses from glaucoma are irreversible, and so the aim of glaucoma treatment is to slow progression and minimize the risk of further damage. Visual loss post filtration surgery in patients with advanced glaucomatous optic nerve damage is a rare but dreaded complication. Functional improvement is not expected. We report the case of a patient who experienced a significant loss of vision following glaucoma surgery that was followed by late visual recovery...

Purpose: To raise awareness of a possible association between continuous positive airway pressure (CPAP) devices and postoperative bleb-related infection. Observations: A 57-year old patient on CPAP presented with unilateral bleb-associated endophthalmitis 32 months after routine ExPress Trabeculectomy with mitomycin C. The offending organism, Streptococcus mitis , is a nonmotile and generally non-virulent pathogen which predominates in the normal human respiratory flora...

PURPOSE: To describe the surgical technique and outcomes in eyes that underwent surgery to replace a failed Ahmed valve by a Baerveldt glaucoma implant in the same quadrant. METHODS: This study was a retrospective case series of 9 patients. Parameters analyzed include age, glaucoma type, prior surgery, complications, intraocular pressure (IOP), visual acuity, and number of glaucoma medications before and after the surgery. Surgical success was defined as having either an IOP below 21▒mm Hg or a 20% IOP reduction, with or without hypotensive agent...
