Summary

Older adults typically have trouble identifying the speech they hear, especially in noisy environments. Fortunately, compared to younger adults, older adults are better able to compensate for difficulties identifying the speech they hear by recruiting the visual system. However, the extent to which older adults can benefit from visual input, and how this influence relates to age-related changes in brain structure and function, have not been thoroughly investigated. The general purpose of this study is to determine how age-related changes in brain structure and function affect how well people hear and see. This study seeks participants with normal hearing to mild hearing loss, who also have normal or corrected-to-normal vision.

Summary

This study aims to create a database of people and families with hereditary retinal dystrophy in South Carolina. Patients with hereditary retinal dystrophy will be offered genetic analysis and counseling with the MUSC Center for Genomic Medicine and may donate cell samples for basic science research at the Department of Ophthalmology. This study will add to the research knowledge base of disease phenotype and epidemiology, and allow expansion of research to determine mechanism and potential therapy for inherited retinal disease

Validation of computer-based saccade and pupillary light reflex measures as biomarkers for progressive supranuclear palsy Save

Summary

This study examines eye movements and the pupil's response to light in progressive supranuclear palsy (PSP), comparing to Parkinson's disease and control subjects without neurological disease. Computerized measures of eye movements and pupil changes will be used. Subjects will also receive an eye exam to rule out other eye diseases. The goal of this study is to use subtle changes in eye movements and the pupil's response to light for earlier diagnosis of PSP.

Keywords
Vision/ Eye
Summary

The purpose of the registry is to provide a mechanism to store clinical data to support future research about postnatal weight gain based risk prediction for severe ROP and secondarily severe ROP and ROP treatment rates. If validated, the predictive model would eventually replace current ROP screening guidelines in determining the necessity and timing of ROP examinations for premature infants.

A PROSPECTIVE OBSERVATIONAL ANALYSIS OF NEAR VISION IN MONOFOCAL PSEUDOPHAKIC CHILDREN Save

Summary

We propose a prospective observational analysis of near visual acuity and stereopsis in pseudophakic children. Visual acuity analysis will be standardized based on age per PEDIG protocols. Results will be stratified by age and by monocular versus binocular surgery. Children will be assessed in their appropriate corrective lenses to control for myopia as a confounding factor. Refractive error will be measured to optimize visual acuity measurement and assess for the potential role of astigmatism in preservation of near visual function.

Summary

Infants born early who are in the neonatal intensive care unit will be included if they meet national guidelines for retinopathy of prematurity (ROP) screening exams. Informed consent will be given to the parent(s) or legal guardians. 1.5-2 ml of blood will be drawn from a vein when the child is enrolled in the study and may be drawn again if the child requires treatment of eye disease. A cheek swab will also be obtained. These biologic samples will be shipped overnight to the University of Utah for genetic analysis. Analysis will determine if a change in gene expression causes retinopathy of prematurity. Infants enrolled in the study will be followed clinically per established ROP screening guidelines. They will not require additional study exams.
