Secondary glaucoma constitutes major sight-threatening complication of pediatric cataract surgery, yet the etiology remains unclear. The purpose of this study was to investigate the long-term anterior segment configuration and the association with secondary glaucoma in pediatric pseudophakia. Ultrasound biomicroscopy (UBM) was performed on 40 eyes of 26 children underwent pediatric cataract surgery and intraocular lens (IOL) implantation. The anterior chamber depth (ACD), angle-opening distance at 500 μm (AOD500), trabecular-iris angle (TIA), central corneal thickness (CCT), structural abnormities, IOL position, IOP, and incidence of glaucoma were evaluated...

PURPOSE: Thin central corneal thickness (CCT) is a risk factor for glaucoma. In 2016 all optometry practices in Scotland were provided with pachymeters aiming to improve risk assessment and accuracy of referrals to secondary care. We examined optometrists' experience and views of pachymetry, including perceived barriers to pachymetry in primary care. METHODS: A questionnaire was sent using the REDCap electronic data capture tool to all 1264 optometrists registered with NHS Education for Scotland (NES)...

INTRODUCTION: To demonstrate that preoperative treatment for 28 days with topical dorzolamide/timolol is non-inferior (Δ = 4 mm Hg) to oral acetazolamide and topical dexamethasone (standard therapy) in terms of intraocular pressure (IOP) reduction 3 and 6 months after trabeculectomy in glaucoma patients. MATERIALS AND METHODS: Sixty-two eyes undergoing trabeculectomy with mitomycin C were included in this monocentric prospective randomized controlled study. IOP change between baseline and 3 months post-op was defined as the primary efficacy variable...

Purpose. The functions of vascular endothelial growth factor (VEGF) in scar formation after trabeculectomy were investigated in a human Tenon fibroblast cell line from glaucoma patients using lentivirus-mediated VEGF shRNA. Methods. Human Tenon fibroblast (HTF) cells were isolated from scar tissue of glaucoma patients during secondary surgery. Lentivirus-VEGF-shRNA was constructed and transfected into HTF cells. Subsequently, VEGF mRNA and protein expression were analyzed using quantitative RT-PCR and western blotting, respectively, and the effects of VEGF knockdown were analyzed...

We reviewed the current literature on the ability of microperimetry to detect non-neovascular age-related macular degeneration (AMD) disease progression. The index test was retinal sensitivity measurement assessed by microperimetry and comparators were other functional measures (best-corrected and low-luminance visual acuities, and fixation stability) and structural parameters [retinal thickness, choroidal thickness, and area of geographic atrophy (GA) determined by color fundus photographs, short-wave or near-infrared fundus autofluorescence]...

Acute angle closure glaucoma (ACG) in the setting of polypoidal choroidal vasculopathy (PCV) is a catastrophic complication that has been documented infrequently in literature. Ours is the second only report that describes hemorrhagic choroidal detachment as an event leading to acute angle closure glaucoma in PCV patients and the first one to describe the use of diode cyclophotocoagulation (CPC) for this condition. The purpose of this article is to familiarize readers with this entity that has an extremely dismal visual prognosis...

PURPOSE: The aim of this study was to evaluate the effect of trabeculotomy (TLO) on glaucoma and endothelial cell loss after penetrating keratoplasty (PK). METHODS: A retrospective study was conducted on consecutive patients who underwent PK and in whom more than 24 months of follow-up was available. Patients were categorized into the PK+TLO group [ie, TLO for post-PK glaucoma (n = 10)] and the PK group [PK alone (n = 73)]. Intraocular pressure (IOP) was evaluated during each follow-up examination...

Primary open angle glaucoma (POAG) is a major type of glaucoma characterized by progressive loss of retinal ganglion cells with associated visual field loss without an identifiable secondary cause. Genetic factors are considered to be major contributors to the pathogenesis of glaucoma. The aim of the study was to identify the causative gene in a large family with POAG by applying whole exome sequencing (WES). WES was performed on the DNA of four affected family members. Rare pathogenic variants shared among the affected individuals were filtered...

BACKGROUND/AIMS: To compare the efficacy and safety of subtenon injection of mitomycin C (MMC) with that of conventional application of MMC-soaked sponges in trabeculectomy. METHODS: In this multicentre randomised clinical trial, 80 consecutive open-angle glaucoma cases were randomised into two groups; group 1 received a subtenon injection of 0.1 mL of 0.01% MMC, while group 2 received 0.02% MMC-soaked sponges.

BACKGROUND: To compare corneal hysteresis (CH) measurements between patients with glaucoma, ocular hypertension (OHT) and glaucoma-like optic discs (GLD)- defined as a cup to disc ratio greater than or equal to 0.6 with normal intraocular pressure (IOP) and visual fields. The secondary aim was to investigate whether corneal resistance factor (CRF) and central corneal thickness (CCT) differ between patient groups. METHODS: In this cross sectional study a total of 123 patients (one eye each) were recruited from a glaucoma outpatient department to undergo ocular response analyser (ORA) testing and ultrasound pachymetry as well as clinical examination...

We compare outcomes following radiotherapeutic and surgical management of iris melanoma. Endpoints included local tumor recurrence, metastases, and common complications. From an initial search that yielded 231 articles, we found 17 relevant studies with 761 eyes. The gender distribution was balanced with a mean age of 52 years. Most studies focused on either proton beam (49.4%) or plaque (31.4%) radiotherapy. Rates of local recurrence (range: 0-8%) and metastatic development (0-5%) were favorable following radiotherapy; however, common complications included cataract (36-73%), glaucoma (3-92%) and corneal conditions (0-33%)...
