OBJECTIVE: A simulated switching study assessed the effects of continuing the same anti-vascular endothelial growth factor (VEGF) treatment among patients who are typically considered for a therapy switch. Post hoc analysis of data from HARBOR (NCT00891735) was undertaken. Patients with neovascular age-related macular degeneration who demonstrated a suboptimal response after 3 or 6 months of ranibizumab treatment were identified as switching candidates. Rather than switching, however, patients continued on ranibizumab treatment, and visual/anatomic outcomes from the timepoint of "hypothetical switch" were examined...

OBJECTIVE: Two strategies were compared for managing moderate hyperopia without manifest strabismus among 1- and 2-year-old children: 1) immediate prescription of glasses vs 2) observation without glasses unless reduced distance visual acuity (VA), reduced stereoacuity, or manifest strabismus. DESIGN: Prospective randomized clinical trial PARTICIPANTS: 130 children 1 to 2 years old with hyperopia between +3.00 diopters (D) and +6.00D spherical equivalent (SE) in at least one eye, anisometropia ≤1...

PURPOSE: To investigate the difference between the segmented axial length (AL) and the displayed AL on an optical low-coherence reflectometry (OLCR) biometer (Part I) and to compare the refractive prediction errors calculated using the segmented and displayed ALs (Part II). DESIGN: Retrospective case series. PARTICIPANTS: 4992 eyes from 4992 subjects in Part I and 1758 eyes from 1758 subjects in Part II. METHODS: In Part I, we calculated the segmented AL as the sum of geometrical ocular segments converted from the optical path length (OPL) in each medium...

DESIGN: Prospective 5-year study. PARTICIPANTS: Patients with NTG with intraocular pressure (IOP) consistently ≤15 mmHg without treatment at baseline. METHODS: Visual field (VF) examinations were performed every 3 months, and disc/peripapillary retina photographs were taken every 6 months...

BACKGROUND: Vernal keratoconjunctivitis (VKC) is a chronic, allergic, and potentially severe ocular disease affecting children and adolescents that can lead to impaired quality of life (QoL) and loss of vision. PURPOSE: This study evaluated the efficacy and safety of an investigational therapy for severe VKC, cyclosporine A cationic emulsion (CsA CE), an oil-in-water emulsion with increased bioavailability versus conventional CsA formulations.

PURPOSE: To compare regional variations in lamina cribrosa (LC) curvature and depth between healthy eyes (Group 1) and naïve eyes with primary open-angle glaucoma (POAG) having superior (Group 2), inferior (Group 3), and both (Group 4) hemifield retinal nerve fiber layer (RNFL) defects. DESIGN: Cross-sectional study PARTICIPANTS: Each group consisted of 39 eyes of 39 Korean patients who were matched for age, sex, and axial length. METHODS: The LC curvature index (LCCI) and LC depth (LCD) were measured in B-scan images obtained using enhanced depth imaging optical coherence tomography at seven locations spaced equidistantly across the vertical optic disc diameter...

PURPOSE: Previous approaches using deep learning algorithms to classify glaucomatous damage on fundus photographs have been limited by the requirement for human labeling of a reference training set. We propose a new approach using quantitative spectral-domain optical coherence tomography (SDOCT) data to train a deep learning algorithm to quantify glaucomatous structural damage on optic disc photographs. DESIGN: Cross-sectional study PARTICIPANTS: : 32,820 pairs of optic disc photos and SDOCT retinal nerve fiber layer (RNFL) scans from 2,312 eyes of 1,198 subjects...

TOPIC: Clinical registries in Ophthalmology CLINICAL RELEVANCE: In recent years advancements in digital technology and increasing use of the electronic medical record in health systems have led to the dramatic growth in large clinical data sets. Clinical data registries are organised systems which collect data on patients diagnosed with a disease or condition, or who undergo a certain procedure. METHODS: A search of the PUBMED database was conducted in January 2018 for clinical registries in ophthalmology...

PURPOSE: GNAQ mutations have been identified in port wine stains (both syndromic and non-syndromic) and melanocytic ocular neoplasms. This study investigates the presence of GNAQ mutations in diffuse- (those associated with Sturge-Weber syndrome (SWS)) and solitary choroidal hemangiomas. PARTICIPANTS: Tissue from 11 patients with the following diagnoses: port wine stain (n = 3), diffuse choroidal hemangioma (n = 1), solitary choroidal hemangioma (n = 6), choroidal nevus (n =1) METHODS: Ten specimens were interrogated with Memorial Sloan Kettering-Integrated Mutation Profiling of Actionable Cancer Targets (MSK-IMPACT), a hybridization capture-based next-generation sequencing assay for targeted deep sequencing of all exons and selected introns of 468 key cancer genes in formalin-fixed, paraffin-embedded tumors...
