Clinical Applications Of Phenomenology: Analysis Of Lived Experience Of Eye Disease, Kimberly Tucker

Graduate Student Research Symposium

This paper presents a phenomenological study that explores the embodied experience of vision loss within the context of eye disease, while also providing a detailed discussion of the methodological approaches utilized in the research. Phenomenology is integrated to address clinical epistemic concerns, particularly the limitations of conventional vision tests in fully capturing perception and the lived experiences of vision loss. This interdisciplinary approach builds on the clinical understanding of eye disease by incorporating the broader dimensions of the lifeworld that intersect with visual impairment in degenerative eye diseases. While standard clinical approaches focus primarily on measurable aspects of visual function, …

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 …

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 …

High Energy Blue Light Induces Oxidative Stress And Retinal Cell Apoptosis, Jessica Malinsky

Capstone Showcase

Blue light (BL) is a high energy, short wavelength spanning 400 to 500 nm. Found in technological and environmental forms, BL has been shown to induce photochemical damage of the retina by reactive oxygen species (ROS) production. Excess ROS leads to oxidative stress, which disrupts retinal mitochondrial structure and function. As mitochondria amply occupy photoreceptors, they also contribute to oxidative stress due to their selectively significant absorption of BL at 400 to 500 nm. ROS generation that induces oxidative stress subsequently promotes retinal mitochondrial apoptosis. BL filtering and preventative mechanisms have been suggested to improve or repair BL-induced retinal damage, …

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 timolol …

Research/Internship In Optometry, Alisha Trivedi

Trick to the Treat of Internships and Research

This is an enriching experience for undergraduate students, giving them a clinical and hands on experience in the field of Optometry. Students will have the opportunity to participate in research, see participants, shadow optometrists, engage in new studies, and possibly present their research at the end of their second semester. Students will work under a health professional at HPD and first observe their work along with the work of the interns before them to get familiar with the position. They will typically see participants for research about 2-3 times a week, and work on their term paper outside of that.
