Time To Refocus Assessment Of Vision In Older Adults? Contrast Sensitivity But Not Visual Acuity Is Associated With Gait In Older Adults, James Loughman, Eoin Duggan, Orna Donoghue,, Rose Anne Kenny, Hilary Cronin, Ciarán Finucane

Articles

Background:

The relationship between measures of visual function and gait related risk factors for falls is unclear. In this study, we examine the relationship between visual function (visual acuity [VA] and contrast sensitivity [CS] at multiple spatial frequencies) and quantitative spatiotemporal gait, using a large, nationally representative sample of community dwelling older adults.

Methods: Participants aged 50 and over were recruited as part of The Irish Longitudinal Study on Ageing (TILDA). VA was measured with the LogMAR chart according to the Early Treatment of Diabetic Retinopathy Study protocol. CS was measured at five spatial frequencies ranging 1.5 to 18 cycles …

Novel Myopia Genes And Pathways Identified From Syndromic Forms Of Myopia, Daniel Ian Flitcroft, James Loughman, Christine F. Wildsoet, Cathy Williams, Jeremy A. Guggenheim

Articles

Clinical phenotypes and syndromes that have refractive errors as a recognized feature were identified using the Online Mendelian Inheritance in Man (OMIM) database. One hundred fifty-four unique causative genes were identified, of which 119 were specifically linked with myopia and 114 represented syndromic myopia (i.e., myopia and at least one other clinical feature). Myopia was the only refractive error listed for 98 genes and hyperopia and the only refractive error noted for 28 genes, with the remaining 28 genes linked to phenotypes with multiple forms of refractive error. Pathway analysis was carried out to find biological processes overrepresented within these …

Optometric Case Finding For Glaucoma In Ireland: An Investigation Of Current Practice Patterns., Catriona Barrett

Doctoral

Optometrists play a vital role in the detection of glaucoma, a leading cause of irreversible blindness. As population screening for glaucoma is neither cost effective nor viable, glaucoma is primarily detected through opportunistic case-finding during routine eye examinations. The present study provides new insight into optometrists’ practice patterns for glaucoma detection in Ireland. Chapters 3 and 4 report on a national survey. The results show that optometrists are well equipped to carry out the traditional glaucoma case finding triad. However, moving towards enhanced services such as monitoring glaucoma suspects or ocular hypertension cases would require some investment in equipment and …

Lipid Biomarkers And Pathway Identification For Contact Lens Related Discomfort, Shyam Panthi

All ETDs from UAB

The purpose of this investigation was to identify possible lipid biomarkers that are associated with contact lens related discomfort and determine whether inflammation as a result of lipid peroxidation or enzymatic arachidonic acid metabolism is associated with such discomfort. Ten microliters of tears were collected from each eye of fifteen subjects (11 non-contact lens wearers, 2 contact lens wearers with discomfort and 2 contact lens wearers without discomfort) and assayed using various chemical extraction methods and mass spectrometry based analytical approaches. This was done to determine whether lipid mediators of inflammation could be identified in low volume (10 l) of …

The Eye As A Window To The Alzheimer’S Disease Brain, Fred Souza

All ETDs from UAB

Alzheimer’s disease (AD) is a debilitating, and the most prevalent, type of dementia that is manifested by cognitive deficits, anomalous protein metabolism, cell loss, and pathological alterations in several neurotransmitter systems, particularly the cholinergic and glutamatergic systems. Moreover, AD is associated with visual deficits that have been reported to occur even in the early stages of the disease and may precede conspicuous cognitive impairment. To date, the underlying causes of the visual deficits and whether they stem from retinal or cortical abnormalities remain poorly understood. The following studies aimed at establishing whether the pathological changes observed in the cerebrum are …

Oxygen Permeability (Dk) Of Silicone-Hydrogel Materials: Relationship With Water, Silicon, And Fluorine Contents, Terin E. Dupre

All ETDs from UAB

To more precisely determine the fundamental relationships between oxygen permeability (Dk), water content (WC), silicon (Si) content, and fluorine (F) content of clinically prescribed silicone-hydrogel (SiHy) materials, identical methodologies for 16 commercially available brands of SiHy materials were performed. Dk and WC were determined according to the ANSI and ISO standards and, with Si and F contents, on the same lot numbers of samples across a common range of available refractive powers. A negative linear relationship was found between Si content and water content. Lotrafilcon A, Lotrafilcon B, and the bulk polymer of Delefilcon A initially deviated from this relationship. …

A Comparison Between Number And Letter Acuities Among Patients, Sarah Berry

All ETDs from UAB

ABSTRACT Purpose: Previous studies have shown that there is an association between visual acuity and Alzheimers’ disease. Untreated visual problems may contribute to cognitive impairment and more progressive cognitive decline. This study investigates the association of chart design, specifically comparing charts using letters versus numbers, to accuracy and repeatability among patients with dementia. Methods: 23 English-speaking subjects diagnosed with moderate to advanced levels of dementia were recruited from two local Birmingham nursing homes. Visual acuities were measured in a randomly selected eye and timed from six different charts: Back-illuminated ETDRS chart with letters, Back-illuminated ETDRS chart with numbers, HOTV cards …

Visual Impairment And Factors Associated With Difficulties With Daily Tasks, Anne T. Riddering

Dissertations

In the past 10 years, the number of American adults with visual impairments has increased from 1 million to 4 million and is expected to double to 8 million people by the year 2050 (The Eye Diseases Prevalence Research Group, 2004; National Eye Institute, 2013). Therapies to treat retinal diseases causing visual impairment, such as diabetic retinopathy and age-related macular degeneration (Massof, 2002; Mogk, 2011), have evolved in the past two decades (Gupta et al., 2013; Hooper & Guymer, 2003), but little research has examined recent population and difficulties with performing daily activities. Different types of professionals, including ophthalmologists, optometrists, …

Development Of Holographic Sensors For Monitoring Relative Humidity And Temperature, Tatsiana Mikulchyk

Doctoral

Photonic structures capable of responding to an analyte with an easily identifiable change in their optical properties have generated wide interest due to their possible application as holographic sensors. Holographic sensors are considered a low-cost, lightweight and disposable technology, and have potential for application in different areas ranging from medical diagnostics to environmental sensing including the monitoring of environmental temperature and relative humidity. In spite of the existing wide range of temperature and humidity sensors, holographic sensors are of special interest as they can provide fast, real-time, reversible or irreversible, visual colorimetric or electronic readouts. The main objective of this …

Relationship Between Ocular Sensory Dominance And Stereopsis, Raheela Saeed Ali

Student Theses, Dissertations and Capstones

Purpose: It is unknown whether individuals with two balanced eyes show quicker response and lower threshold in fine stereoscopic detection. Previous methods to measure ocular dominance were primarily qualitative, which do not quantify the degree of dominance and show limitation in identifying the dominant eye. In this study, we aimed at quantifying the difference of ocular strength between the two eyes with ocular dominance index (ODI) and studying the association of ocular balance between the two eyes with stereoscopic detection. Methods: Stereoscopic threshold was measured in thirty-three subjects. Stereopsis was measured with random dot stimuli. The minimal detectable disparity (Dmin) …

A Systems Framework For Development Projects And Partnerships In Eye Health Training, Diane Wallace

Doctoral

Purpose: Development projects in eye health have evolved over the past fifteen years in response to VISION 2020: The Right to Sight. Estimates that 285 million people, mainly in the developing world, are needlessly vision impaired largely due to the lack of trained eye health professionals have moved development initiatives away from vertical, service delivery approaches towards the establishment of more sustainable, locally owned professional training programmes in an effort to ensure long term production of adequately trained human resource capacity to address this challenge. The Mozambique Eyecare Project was one such initiative, established as a solution to the challenge …

Development Of A Surgical Instrument Prototype To Perform A More Precise Capsulorhexis, Kirk Haugen

Journal of Interdisciplinary Undergraduate Research

Performing capsulorhexis is often considered the most difficult part of cataract surgery. Not only is it difficult, but performing it correctly is important for refractive outcomes.⁴ Inaccurate capsulorhexes are associated with complications including posterior capsular opacification, capsular fibrosis, and capsular phimosis.⁶ This study investigates the possibility of a proposed surgical instrument producing more precise capsulorhexes as determined by the circularity index. 60 capsulorhexes were performed on cigarette paper laid over clay - half using the continuous curvilinear capsulorhexis (CCC) method, and half using the proposed instrument. The precision of the capsulorhexis was then measured using the circularity index. …

To Screen Or Not To Screen Parent’S Perceptions Of Eye Care Prevention For Pre-School Age Children, Bonnie E. Keaton

Honors Theses

One in 20 children is at risk for permanent vision loss from disorders such as amblyopia and strabismus (Why Save Sight, 2016). Despite vision disorders and childhood blindness being a common disability in children, preventative vision screenings are not at the center of prevention discussions. Studies have suggested that vision screenings for young children are beneficial in preventing permanent vision loss (Vision Screenings for Healthy Vision, 2016). Vision screenings for preschool children are important and require more attention in the United States. This descriptive study addressed parental perceptions of early detection of vision problems among preschoolers in southeast Mississippi as …

Framing Professional Programs Within Development Projects: Driving Longer Term Recognition And Integration, Diane Wallace, James Loughman, Kovin Naidoo

Articles

Background: Optometry has, over the past ten years, emerged as a profession strategically positioned to address the burden of uncorrected refractive error in developing countries. Estimates suggest that 285 million people in the world are needlessly visually impaired, mainly due to the lack of trained eye health professionals in the developing world. Development initiatives in eye care have therefore moved away from vertical, service delivery approaches to supporting the establishment of more sustainable, locally owned training programs. This research is based on one the evaluation of one such initiative known as the Mozambique Eyecare Project.

Methods: This study followed a …

This study was designed to develop a comprehensive framework of competency standards for ophthalmic technicians and optometrists, in Mozambique. This could then inform the evolution of socially responsive curricula for both cadres. Methods A modified Delphi technique was used with a ten member expert panel consisting of optometrists, ophthalmic technicians and ophthalmologists, all with experience of working in a developing country context. The competencies were derived from literature, primary research data and observations from a competency development workshop. The first round involved scoring the relevance …

The Acceptability And Visual Impact Of 0.01% Atropine In A Caucasian Population, James Loughman, Daniel Ian Flitcroft

Articles

Myopia is a condition of enormous public health concern, affecting up to 2.5 billion people worldwide. The most effective treatment to prevent myopia progression is atropine but at the cost of accommodative paresis and mydriasis, necessitating the use of bifocal glasses. Low-dose atropine (0.01%) has been found to be almost as effective with significantly reduced side effects. Since there are well-recognised differences in the effect of atropine between heavily pigmented Asian eyes and Caucasian eyes, this study aimed to determine the acceptability and tolerability of 0.01% atropine (by measuring visual performance and quality of life) as a treatment for myopia …
