Sagging Eye Syndrome--An Overlooked Diagnosis, Zachary Tlumak Od, Theresa Zerilli-Zavgorodni Od, Nancy Shenouda-Awad Od
Optometric Clinical Practice
Abstract
Background: Sagging Eye Syndrome (SES) is a relatively unknown cause for binocular distance diplopia. SES presents with an acquired comitant or non-comitant small angle esotropia and/or hypotropia commonly occurring in the elderly population. Inferior displacement of the lateral rectus secondary to age-related degeneration of orbital connective tissue and extraocular muscles appears to be responsible for the ocular misalignment. SES patients often present with new onset or progressively worsening distance diplopia, typically warranting neuroimaging. However, through understanding SES, eye care practitioners may identify these cases, avoiding unnecessary imaging studies. Case Report: A 90-year-old male presented with complaints of intermittent horizontal …

Stem Cell Technology For Age Related Macular Degeneration Intervention, Laura Valdez
Research Symposium
Retinal pigmented epithelium (RPE) cells are located between the choroid and photoreceptors within the eye and are essential to provide nutrients from blood to rods and cones, as well retinoids of the visual cycle. Vision loss and various ocular diseases are attributable to the degeneration or dysfunction of the RPE cells, leading to blindness.One of the major ocular problem from RPE dysfunction is macular degeneration. Age-related macular degeneration (AMD) can be frequently diagnosed in patients over the age of 60. In the early stages of AMD, some symptoms may not be noticeable but will lead to vision loss in both …

The Importance Of Contrast Sensitivity, Color Vision, And Electrophysiological Testing In Clinical And Occupational Settings, Frances Silva
Theses & Dissertations
Visual acuity (VA) is universally accepted as the gold standard metric for ocular vision and function. Contrast sensitivity (CS), color vision, and electrophysiological testing for clinical and occupational settings are warranted despite being deemed ancillary and minimally utilized by clinicians. These assessments provide essential information to subjectively and objectively quantify and obtain optimal functional vision. They are useful for baseline data and monitoring hereditary and progressive ocular conditions and cognitive function. The studies in this dissertation highlight the value of contrast sensitivity, color vision, and cone specific electrophysiological testing, as well as the novel metrics obtained with potential practical clinical …

Occupational Therapy Curricula Patterns For Acquired Brain Injury-Related Vision Disorders For Entry-Level Programs: A Survey, Laura Schmeiser, Alicia Reiser, Caitlyn Foy
The Open Journal of Occupational Therapy
Occupational therapists are among the first providers to encounter individuals after an acquired brain injury (ABI). Evidence suggests that most occupational therapists learn about ABI-related vision disorders from continuing education and on-the-job training. A better understanding of entry-level curricula patterns for ABI-related vision disorders is important because of their high prevalence and impact on occupational performance. A descriptive online survey was administered to occupational therapy educators at ACOTE-accredited entry-level programs to explore curricula patterns for ABI-related vision disorders. Of 1,391 occupational therapy educators invited to participate, 71 (5%) began the survey, and 66 met the inclusion criteria. Vision screening methods …

Optical Characterisation Of Holographic Diffusers And Bangerter Foils For Treatment Of Amblyopia, Matthew Hellis, Suzanne Martin, Matthew Sheehan, Kevin Murphy
Articles
Amblyopia is a significant issue for children worldwide, and current treatment methods have drawbacks that can hinder treatment effectiveness and/or patient experience. This study proposes a new treatment method using holographic diffusers while also comparing their optical characteristics to a current treatment method (Bangerter foils). Holographic diffusers were developed by optically patterning thin polymer layers on a micron scale. Two compositions of photopolymer (acrylamide and diacetone acrylamide based) are analysed herein. Characterisation shows that holographic diffusers of either composition can achieve a wide range of on-axis intensity reductions, allowing for precise and customisable treatment levels by altering recording exposure time …

Comprehensive Analysis Of The Retinal Cell Contributions To The Human Erg, Christopher W. Tyler
MODVIS Workshop
Purpose. Standard electroretinogram (ERG) protocols are largely designed to isolate the responses of the rod and cone retinal pathways, including the use of adapting backgrounds to suppress unwanted off-pathway responses. Here, we record spectral ERGs in the low-to-high mesopic sensitivity range in the absence of any adapting background in order to assess interactions between the pathways.
Methods. We have developed a comprehensive neuroanalytic model of the component structure of the ERG driven by knowledge of the underlying retinal physiology, to enhance its power as a critical diagnostic tool for a broad range of both retinal and systemic dysfunctions. The ERG …

Design And Synthesis Of Peripherally Selective Endocannabinoid Enzyme Inhibitors For Ocular Indications, Kezia Reji Thomas
Senior Honors Theses
Peripherally selective compounds have been found to stimulate endocannabinoid receptor activity, which has been observed to have positive physiological effects such as ocular wound healing and inflammation control. The activation of the cannabinoid 1 receptor via binding of the endogenous ligands, anandamide and 2-arachidonoylglycerol, has been indicated to elicit these effects. Both ligands are controlled by two hydrolase enzymes, fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL), which can be targeted for therapeutic inhibition. Sulfonamide derivatives of JZL195 containing carbamate functionalities in the southern region of the inhibitor compounds were produced using novel carbamate exchange reactions. Polar functionalities were …
