Quality Improvement Initiative To Increase Comprehensive Eye Exams In Patients With Diabetes, Julia Khoury

Doctor of Nursing Practice

Diabetic retinopathy is the most common microvascular complication associated with poorly controlled diabetes. Yet, only 60% of the diabetic population receives an annual eye examination by an eye specialist. Retinal imaging increases surveillance of retinopathy, however, it does not take the place of a comprehensive eye examination by an ophthalmologist or optometrist. The aim of this quality improvement project was to increase comprehensive eye examinations in patients with diabetes aged 18 to 75 years in a family practice that recently purchased a retinal imager. This quality improvement project occurred over a 10-week period. Project objectives included increasing comprehensive dilated eye …

Welder’S Maculopathy; A Case Report, Christina E. Morettin Od, Bruce A. Teitelbaum Od

Optometric Clinical Practice

Background: Outer retinal damage can occur when excessive ultraviolet (UV) radiation reaches the retina. The most common etiology is from the sun, known as solar retinopathy, especially when individuals observe solar eclipses without appropriate eye protection. Another cause of UV retinopathy that is not frequently encountered in practice is arc welding, causing Welder’s Maculopathy. Fortunately, the prognosis of the UV retinopathies is quite favourable, as many fully recover after the initial insult to the retina. This retrospective case review aims to outline the clinical manifestation of this maculopathy and current opinions on its etiology and diagnosis.

Presumed Diffuse Unilateral Subacute Neuroretinitis: A Review Supported By A Unique Case, Kirsti K. Ramirez Od, Joseph Pizzimenti Od, Jeannette Wong-Powell Od, Jeffrey Rabin Od

Optometric Clinical Practice

Diffuse unilateral subacute neuroretinitis (DUSN) is a rare, sight-threatening inflammatory condition caused by a nematode. It typically affects healthy children and young adults. Various nematodes have been implicated, including those that originate from dogs and raccoons. Late stage findings include optic nerve atrophy, retinal arterial attenuation, “retinitis pigmentosa-like” retinal pigmentary changes, and central and peripheral vision loss. We present a case study of long-standing DUSN. The combination of optical coherence tomography (OCT) and visual electrophysiology testing proved invaluable in establishing a presumptive diagnosis of this rare condition.

Anterior Subcapsular Cataract Secondary To Black Mold Exposure, Katherine B. Lynch Od, Bruce A. Teitelbaum Od

Optometric Clinical Practice

A case report of a 31-year-old woman who developed anterior subacapsular cataracts, and associated dermatological signs, after exposure to black mold. While atopic illness is commonly seen in childhood, a growing body of literature supports adult onset atopic dermatitis. Anterior subcapsular cataracts are pathognomonic for atopic illness, and can support a definitive and expedited dermatologic diagnosis of adult onset disease.

Association Of Total Zinc Intake With Myopia In U.S. Children And Adolescents, Niamh Burke, John Butler, Daniel Ian Flitcroft, Daniel Mccartney, James Loughman

Articles

Significance: This present study advances our knowledge on the role of lifestyle factors in myopia (short-sightedness), specifically dietary factors. It has been suggested in previous studies that lower zinc status is associated with myopia; however, this article shows no relationship between dietary zinc intake and myopia in U.S. adolescents. Purpose: It has been suggested that low zinc levels may contribute to the development of myopia. The aim of the present study is to examine, for the first time in a Western population, the association of total dietary and supplement zinc intake with myopia. Methods: A total of 1095 children/adolescents aged …

Clinical Accuracy Of The Nidek Ark-1 Autorefractor, Nabin Paudel, Sameep Adhikari, Ajit Thakur, Bhairaja Shrestha, James Loughman

Articles

Autorefractors are commonly used by eye care practitioners worldwide as a starting point for clinical prescribing and by researchers as an instrument to study development of refractive errors and accommodation. This study demonstrates that the Nidek ARK-1 provides a reasonable and repeatable estimate of refractive error.

Prevalence Of Ametropia, Amblyopia And Visual Impairment In Schoolchildren In Ireland, Siofra Harrington

Doctoral

Background: Uncorrected refractive error is an avoidable cause of visual impairment (Naidoo et al., 2016). Currently, there is a lack of adequate data on eye and vision disorders in schoolchildren in Ireland. Accurate prevalence estimates of refractive error and vision disorders are necessary to determine their impact on public health and to assess the need for interventions (McCarty and Taylor, 2000). Purpose: This study reports the prevalence of ametropia, presenting visual impairment, amblyopia and provides population norms for ocular biometric measures in schoolchildren in Ireland. Links between refractive error and demographic and lifestyle factors were investigated. The impact of poor …

The Relationship Of An Ipad, A Video Magnifier, And Large Print Text With Oral Reading Outcomes For Children With Low Vision, Rosemary L. Nave Stawasz

Dissertations

Low vision may cause a decrease in visual performance and interfere with daily functioning, especially reading print or text materials. Reading standard text can be particularly challenging for students with low vision in an educational setting and can reduce oral reading rates. Students with low vision may use large print or low vision devices for reading. Limited evidence currently exists to compare oral reading outcomes across various reading media for children with low vision.

The purpose of this exploratory project was to examine oral reading rate, fluency, and comprehension among children with low vision when using an iPad, a video …

Ozone Induced Effects On The Mammalian Visual System, Jordan Wetz

Theses & Dissertations

Research Focus. Millions of people who suffer from retinal disease live in air-polluted environments. The impact of the gaseous air pollutant ozone (O₃), a strong oxidant, on the retina is unknown. The aim of the present study is to compare the electroretinographic responses between control (no O₃ exposure) and O₃ -exposed rats and to better understand the effects of O₃ on retinal function.

Materials and Methods. Age-matched adult female rats were separated into two groups (N = 6), 3 control and 3 experimental. The experimental group was exposed to 0.4 ppm O₃ for …

Genetic Analysis Localizes A Novel Locus On Chromosome 4q For The Glaucoma Endophenotype, Cup-To-Disc Ratio: The Jiri Eye Study, Sarah E. Miller, Nicholas B. Blackburn, Suman S. Thapa, Sandra Laston, Satish Kumar, Juan M. Peralta, Janardan Subedi, John Blangero, Sarah Williams-Blangero, Matthew P. Johnson

School of Medicine Publications

Purpose: Glaucoma is a heterogeneous disease influenced by genetic risk factors. However, not all genetic risk factors have been identified. The aim of this project is to localize genetic factors influencing known glaucoma endophenotypes: intraocular pressure (IOP), central corneal thickness (CCT), and vertical cup-to-disc ratio (VCDR).

Methods: This family-based study design utilizes phenotypic and genomic data from a single well-characterized pedigree residing in the Jiri region of Nepal. Measures of IOP, CCT and VCDR were obtained by Goldmann applanation tonometry, OCT, and slit lamp biomicroscopy, respectively. Using a genome-wide genotype data set (~550,000 SNPs), we performed a genome-wide linkage scan …

Age Differences In Attentional Capture Effects Of Emotional Faces, Shelby King

Mahurin Honors College Capstone Experience/Thesis Projects

Sustained attention is necessary to accurately complete cognitive tasks. However, sustained attention can often be disrupted by distracting information. When distractors contain emotional content, past research suggests that they might attract attention. The rapid detection of emotional information is important in everyday life because emotion often emerges in social interaction, including unpleasant interactions where others might pose a threat. The attentional capture effects of emotional faces were explored by inserting them into a visual search task that included differing levels of perceptual load. Twenty-five younger adults and twenty older adults identified target letters in standard trials containing distracting elements, but …

Effect Of Aflibercept On Macular Retinal Layers And Peripheral Non Perfusion In Subjects With Proliferative Diabetic Retinopathy, Swetha Bindu Velaga

Student Theses, Dissertations and Capstones

Background: The relation between UWF fluorescein angiography (FA) and retinal non-perfusion were studied previously. The relationship between retinal thickness and retinal non-perfusion in subjects with diabetic retinopathy has not been studied using SD-OCT and UWF. Thus, in this current study we used SD-OCT to visualize the individual layers of retina and to evaluate whether the extent of non-perfusion is correlated with macular retinal layer thickness in subjects with PDR with no diabetic macular edema.

Methods: In this prospective longitudinal multicenter, randomized study a total of 36 eyes of thirty six subjects were included in final analysis. Subjects with any history …

Practice Makes The Deficiency Of Global Motion Detection In People With Pattern-Related Visual Stress More Apparent, Jana Wegrzyn

Student Theses, Dissertations and Capstones

Pattern-related visual stress (PRVS) refers to the perceptual difficulties experienced by some individuals when exposed to high contrast striped patterns. People with PRVS were reported to have reduced sensitivity to global motion at baseline testing and the difference disappears at a second estimate. The present study was to investigate the effect of practice on global motion threshold in adults with and without PRVS. Methods: A total of 101 subjects were recruited and the Wilkins & Evans Pattern Glare Test was used to determine if a subject had PRVS. The threshold to detect global motion was measured with a random dot …

Long Term Efficacy Of A Supraciliary Micro-Stent Combined With Cataract Surgery In The Treatment Of Glaucoma, Michael Robert Mcfarland

Student Theses, Dissertations and Capstones

Purpose: The purpose of this study is to evaluate the long-term efficacy of supraciliary micro-stent implantation in combination with phacoemulsification in the treatment of mild-moderate primary open angle glaucoma (POAG). Methods: Retrospective data of patients previously enrolled in the “Study of an Implantable Device for Lowering Intraocular Pressure in Glaucoma Patients Undergoing Cataract Surgery” (COMPASS trial), in which patients with mild-moderate POAG had undergone either cataract surgery alone or cataract surgery combined with implantation of a supraciliary micro-stent, were collected. Eligible patients had since exited the trial and had 5-8 years of postoperative data available. The primary outcome measure was …
