Within-subject standard deviation (Sw), test-retest (TRT), coefficient variation (COV) for assessing Bland-Altman plots between...
Abstract Aggregation prone molecules, such as tau, form both historically well characterized fibrillar deposits (neurofibrillary tangles) and recently identified phosphate-buffered saline (PBS) extract species called proteopathic seeds. Both can cause normal endogenous tau to undergo templated misfolding. The relationship of these seeds the fibrils that define tau-related diseases is unknown. We aqueous extractable sarkosyl insoluble derived from human Alzheimer brain using mass spectrometry...
To evaluate the relationship between central corneal thickness and intraocular pressure (IOP) measured by iCare rebound tonometry (RBT) in normals glaucomatous patients.Of 102 patients screened, we included 62 eyes with glaucoma 77 normal this hospital-based cross-sectional study. IOP was RBT which averages 6 readings followed Goldmann applanation (GAT). Central (CCT) obtained ultrasound pachymetry an average of 5 consecutive readings. Relationship CCT studied regression techniques using...
Purpose: The purpose of this study is to assess the repeatability and agreement five imaging devices, namely, Pentacam (Oculus), Sirius (CSO), Orbscan IIz (Bausch Lomb), Corvis ultrasound pachymetry (UP, Tomey) in measuring steep keratometry (sKm), flat (fKm), central corneal thickness (CCT), thinnest (TCT), anterior chamber depth (ACD) healthy individuals. Design: This was prospective, comparative study. Subjects: Forty-six Indian patients. Materials Methods: eyes 46 participants underwent...
Abstract Purpose To assess the repeatability of lipid layer thickness (LLT) measurement using LipiView® interferometer after daily disposable contact lens (CL) wear and correlation with ocular comfort in soft wearers. Methods A prospective study was conducted over two consecutive months, wherein CL wearers ( n = 20) wore either Somofilcon or Verofilcon CLs a crossover design, switching lenses 1 month. The pre‐corneal tear film LLT measured at end each month had been worn for least 6 h. Using...
Introduction: Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory involving 0.5–1% of the global population. Coexistence RA and thyroid dysfunction now increasingly being recognized. This due to shared factors involved in pathogenesis disease. Thyroid disorder an important amplifier disease activity, thereby impairing quality life. Objectives: To study prevalence pattern patients, compare activity among patients with those without dysfunction, possible association between severe...
Objectives: To establish a normative database for retinal nerve fiber layer (RNFL) thickness in children<18 years by spectral-domain optical coherence tomography (SD-OCT). Methods: Children <18 years, who were consecutively enrolled from July-August 2011 this cross-sectional hospital study, underwent Cirrus SD-OCT. Recorded demographics and clinical characteristics included age, sex, axial length, spherical equivalent, intraocular pressure (by Perkins tonometry) cup disc ratio. The RNFL full...
SIGNIFICANCE Modern highly oxygen-permeable nonfenestrated scleral lenses induce approximately 1 to 2% corneal edema after short periods of lens wear in healthy individuals. This study investigated the magnitude and regional variation lens-induced central penetrating keratoplasty. PURPOSE The purpose this was examine a period post–penetrating keratoplasty eyes control group with corneas. METHODS Nine (nine participants; mean age, 32 years) were fitted (Dk 100 × 10 −11 cm 3 O 2 (cm)/[(s) (cm...
To quantify the effect of a single scleral lens design on visual acuity and ocular higher-order aberrations in eyes with post-LASIK ectasia, keratoconus pellucid marginal degeneration (PMD) that could not achieve satisfactory vision spectacles or soft contact lenses.Forty-six 28 participants fitted diagnostic lenses (KeraCare) were analysed, including 19, 15 12 PMD, respectively. Corrected distance (CDVA) measured prior to wear during after 60 min settling. An i-Trace aberrometer was used...
Purpose: To compare and determine the repeatability of central corneal thickness (CCT) measurements using four noncontact pachymetry instruments in eyes with keratoconus. Materials Methods: The CCT consecutive patients keratoconus was measured during a single visit swept source optical coherence tomography (SS-OCT, Casia SS-1000°CT, Tomey, Nagoya, Japan), rotating Scheimpflug camera system (Pentacam, Oculus Optikgerate GmbH, Wetzlar, Germany), scanning slit topographer (Orbscan IIz...
A 17-year old boy, with decreased vision in right eye for 15 days, presented retinal periphlebitis multiple quadrants of the and partially active serpiginous-like choroiditis left eye. Tuberculin test was positive (16 mm induration), chest X-ray showed hilar lymphadenopathy. The patient treated a 9-month course anti-tubercular therapy tapering dose oral corticosteroids. Both vasculitis lesions resolved over 3-4 months. Retinal neovascularization laser photocoagulation. There no recurrence an...
Abstract Purpose Visual rehabilitation following penetrating keratoplasty is the primary indication for approximately 15% of all scleral lens fittings. Since corneal biomechanics are altered keratoplasty, aim this study was to quantify changes in anterior optics short‐term wear eyes with grafts. Methods Scheimpflug images were obtained before and after a period (mean 6.3 ± 1.4 h), from that had previously undergone (10 nine participants, mean age 31 9 years). Corneal power thickness data...
Objective: To compare corneal biomechanics and intraocular pressure (IOP) in keratoconus penetrating keratoplasty eyes before after nonfenestrated scleral lens wear. Methods: Twenty-three participants were enrolled, 37 included the analysis (11 26 keratoconus). A range of biomechanical parameters IOP measured using CORVIS ST 8 hr wear (Keracare, Acculens, Denver, CO). Results: Before wear, displayed significantly greater median values for central thickness (97 μm thicker, P =0.02), (3.89 mm...
Abstract Background Clinical studies have long observed that neurodegenerative disorders display a range of symptoms and pathological features and, in some cases, overlap, suggesting these diseases exist on spectrum. Dementia with Lewy Bodies (DLB), synucleinopathy, is prominent example, where symptomatic similarities tauopathy, Alzheimer’s disease, are observed. Although tau pathology has been DLB, the interplay between α-synuclein poorly understood at molecular level. Methods Quantitative...
