Vision Therapy Rehabilitation Of Post-Concussion Visual Impairments, Sarah Morton 2018 University of Wyoming

Vision Therapy Rehabilitation Of Post-Concussion Visual Impairments, Sarah Morton

Honors Theses AY 17/18

Concussion is a common, mild form of traumatic brain injury that is caused by blunt force trauma to the head. Concussion can be caused by a wide variety of situation, commonly sports collisions, automobile accidents, and falls. Signs of concussion include a loss of consciousness, temporary amnesia, and disorientation. Severe concussion can result in visual impairments such as blurred vision, light sensitivity, attention deficits, impaired memory, and double vision. Vision therapy can significantly or completely improve many of these visual impairments. Vision therapy is a series of procedures monitored by an optometrist that are designed to improve visual movements and ...

Development Of Sensitive Holographic Devices For Physiological Metal Ion Detection, Sabad-E- Gul, Suzanne Martin, John Cassidy, Izabela Naydenova

Conference Papers

The development of selective alkali metal ions sensors in particular is a subject of significant interest. In this respect, the level of blood electrolytes, particularly H+, Na+, K+ and Cl- , is widely used to monitor aberrant physiologies associated with pulmonary emphysema, acute and chronic renal failure, heart failure, diabetes. The sensors reported in this paper are created by holographic recording of surface relief structures in a self-processing photopolymer material. The structures are functionalized by ionophores dibenzo-18-crown-6 (DC) and tetraethyl 4-tert-butylcalix[4]arene (TBC) in plasticised polyvinyl chloride (PVC) matrix. Interrogation of these structures by light allows indirect measurements of chemical ...

Contrast Sensitivity Testing In Normal Vision: Performance With Letter Vs. Continuous Text, Kristen Davis, Marc Taub, Patricia Cisarik

Interprofessional Optometry

Introduction: Contrast sensitivity is a visual element used in optometric examinations to help assess visual capacity. This study compared two formats of contrast sensitivity tests, ETDRS Letters and Continuous Text.

Methods: Contrast sensitivity was measured in 75 subjects, who met inclusion criteria, using the Adult Near Contrast Test. Patients’ verbal readings provided data for the formats at five contrast levels. Results: Average visual acuity and number of lines/paragraphs read correctly decreased with decreasing contrast. ANOVAs showed significant differences by contrast level in total words and total letters (ps< 0.001) and a Pearson correlation gave high correlations between the contrast sensitivity readings of the two formats except at 100% contrast (ps< 0.05; p= 0.69).

Conclusion: Analysis revealed that contrast sensitivity readings from the different formats ...

Latanoprost And Timolol In Hydrogel Soft Drug-Dispensing Contact Lenses: A Comparative Analysis, Neha Potdar 2017 Virginia Commonwealth University

Latanoprost And Timolol In Hydrogel Soft Drug-Dispensing Contact Lenses: A Comparative Analysis, Neha Potdar

Virginias Collegiate Honors Council Conference

Glaucoma patients only can instill glaucoma eye drops. This results in 1-7% absorption of the medication. Surveys show that patients forget to take their medication and have difficulty inserting their eye drops. Researchers at the Massachusetts Eye and Ear Infirmary have developed latanoprost drug-dispensing hydrogel soft contact lenses that dispense the drug to help facilitate the process. However, some glaucoma patients do not respond to latanoprost because they have uveitic glaucoma or do not want to experience latanoprost’s ocular side effects. Patients need an alternative which can be inserted into these contact lenses. Another commonly used glaucoma drug is ...

Targeted Aav5-Smad7 Gene Therapy Inhibits Corneal Scarring In Vivo, Suneel Gupta, Jason T. Rodier, Ajay Sharma, Elizabeth A. Giuliano, Prashant R. Sinha, Nathan P. Hesemann, Arkasubhra Ghosh, Rajiv R. Mohan

Pharmacy Faculty Articles and Research

Corneal scarring is due to aberrant activity of the transforming growth factor β (TGFβ) signaling pathway following traumatic, mechanical, infectious, or surgical injury. Altered TGFβ signaling cascade leads to downstream Smad (Suppressor of mothers against decapentaplegic) protein-mediated signaling events that regulate expression of extracellular matrix and myogenic proteins. These events lead to transdifferentiation of keratocytes into myofibroblasts through fibroblasts and often results in permanent corneal scarring. Hence, therapeutic targets that reduce transdifferentiation of fibroblasts into myofibroblasts may provide a clinically relevant approach to treat corneal fibrosis and improve long-term visual outcomes. Smad7 protein regulates the functional effects of TGFβ signaling ...

Neuro-Behavioral Effects Of Luminance Level On Visual Performance And Discomfort With High Dynamic Range Displays, Shun-Nan Yang, Manho Jang, Ju Liu

VPI Research

High dynamic range (HDR) displays are designed to simulate the range of perceived brightness afforded by the real world. To study how visual performance and visual comfort are affected by luminance level, 34 participants with normal vision were first asked to discriminate the brightness of two circles presented on LCD and OLED screens to determine the luminance threshold for brightness discrimination. They then judge the orientation of a circular grating target alternating with a luminance circle while their visually-evoked potentials and viewing discomfort was assessed. Results show contrast ratio is more important than luminance difference in brightness discrimination. Regression model ...

Novel Myopia Genes And Pathways Identified From Syndromic Forms Of Myopia, D. 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 ...
