Advances in anterior segment imaging modalities have contributed new insights towards a better understanding of the various mechanisms of angle-closure glaucoma (ACG). This development is key to good decision making when confronted with angle-closure patients needing appropriate therapy. Surgical management of ACG remains an integral part of glaucoma patient care. The distinctive anatomy of angle-closure eyes and the few objective lines of evidence to support the effectiveness of the different surgical treatment options present a challenge to glaucoma surgeons...

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...

Sylvain Roy, André Mermoud
Filtering surgery evolved from the classic trabeculectomy, in which penetration into the anterior chamber is a necessary step, toward nonpenetrating deep sclerectomy. The first procedure presents several serious complications, such as durable hypotony, hyphema, flat anterior chamber, choroidal detachment, endophthalmitis, and surgery-induced cataract. To avoid such drawbacks, a novel nonpenetrating technique was designed to improve the predictability of the intraocular pressure (IOP)-lowering action, while reducing the incidence of the immediate postoperative complications encountered with the penetrating method...

OBJECTIVE To compare platelet function and viscoelastic test results between healthy dogs and dogs with chronic kidney disease (CKD) to assess whether dogs with CKD have platelet dysfunction and altered blood coagulation. ANIMALS 10 healthy control dogs and 11 dogs with naturally occurring CKD. PROCEDURES Blood and urine were collected once from each dog for a CBC, serum biochemical analysis, urinalysis, and determination of the urine protein-to-creatinine ratio, prothrombin time, activated partial thromboplastin time, plasma fibrinogen concentration, and antithrombin activity...

STUDY DESIGN: A consecutive and prospective longitudinal study. OBJECTIVE: To propose an integrated multidimensional maturity assessment that was designated as forming a reliable system precisely predicting the high-risk occurrence of peak angle velocity (PAV) in a group of progressive braced female idiopathic scoliosis (IS).

PURPOSE: To determine if the anterior choroid is involved in ocular change during the Valsalva manoeuvre (VM). MATERIALS AND METHODS: Fifty-three healthy volunteers aged 18-65 years with normal visual field test results and no history of intraocular pressure (IOP) exceeding 21 mm Hg were recruited. Anterior and posterior choroidal changes before and during VM were recorded by ultrasound microscope and swept-source optical coherence tomography, respectively. Parameters of the anterior segment included ciliary body thickness (CBT0), thickness of the choroid at a distance of 4 mm from the root of the iris (CT4), anterior placement of the ciliary body (APCB) and trabecular-ciliary angle (TCA)...

Acute primary angle closure (APAC) is an ocular emergency and requires immediate management to avoid blindness. Narrow anterior chamber angle, advanced age, female gender, and Asian ethnic background are considered risk factors for APAC. The predictable power of these factors is, however, relatively poor, and many questions remain unanswered because only a relatively small proportion of anatomically predisposed eyes eventually develop APAC. We summarize the potential roles of various factors in the pathogenesis of APAC...

PURPOSE: Implanting intraocular lens (IOL) in proper direction is important in cataract surgery to reduce the possibility of undesirable complications. We experienced a case who underwent vitrectomy combined with cataract surgery and developed secondary angle closure glaucoma caused by IOL misdirection. Goniosynechialysis (GSL) and repositioning of IOL successfully ameliorated the high intraocular pressure (IOP). CASE REPORT: A 64-year-old male with massive vitreous hemorrhage underwent vitrectomy combined with cataract surgery...

In clinical practice, Primary Acute Angle-closure Glaucoma (APACG) is a common disease with an increasing incidence rate and blind rate, and has attracted attention of medical researchers. When a patient suffers both primary acute glaucoma and high tension glaucoma, drug therapy can achieve limited efficacy, and operative treatment is necessary on this occasion. This research mainly explored the safety in treating high tension APACG by compound trabeculectomy, and observed the clinical treatment effect and incident rate of postoperative complications after compound trabeculectomy...

OBJECTIVES: Population-based screening for glaucoma has been demonstrated to be cost-effective if targeted at high-risk groups such as older adults and those with a family history of glaucoma, and through use of a technician for conducting initial assessment rather than a medical specialist. This study attempts to investigate the cost-effectiveness of a hypothetical community screening and subsequent treatment programme for glaucoma in comparison with current practice (i.e. with no screening programme but with some opportunistic case finding) in the urban areas of India...

This case study aims to elucidate the correlation between the hOGG1 , APE1 and XRCC1 gene polymorphisms to the susceptibility and clinicopathological features of primary angle-closure glaucoma (PACG) in a Chinese Han population. Blood samples were obtained from 258 PACG patients (case group) and 272 healthy volunteers (control group). Polymerase chain reaction with sequence specific primer (PCR-SSP) was used to determine the allele frequencies and genotype distributions of the hOGG1 , APE1 and XRCC1 genes. The risk factors of PACG were determined using logistic regression analysis...

OBJECTIVE: Inflammatory mechanisms may have a role in the pathogenesis of primary angle closure glaucoma (PACG). The objective of this study was to investigate the diagnostic value of white blood cell (WBC), neutrophil, neutrophil to lymphocyte ratio (NLR), and lymphocyte to monocyte ratio (LMR) in patients with PACG and its association with glaucoma severity. METHOD: The study was retrospectively assessed in 771 consecutive PACG patients and 770 control subjects, laboratory parameters and clinical parameters were obtained from a medical data platform...

Topiramate (TPM) is a drug used in migraine prophylaxis. It is involved in the bilateral angle-closure glaucoma due to idiosyncratic response. This side effect is rare but can lead to irreversible vision loss if it is not recognized in time and if it is not managed immediately by an ophthalmologist.
