Developing An Assessment Of Reading Impairment And Its Impact On Occupational Performance In Older Adults With Glaucoma In A Metropolitan Area Of The Southeastern Us: A Mixed Methods Approach, Robin Deacy
All ETDs from UAB
According to the United States Administration on Aging (AOA, 2014), the population of individuals over 65 will be 98 million by the year 2060, doubling its 2014 estimates. As our population ages, the prevalence of glaucoma increases. Vision loss resulting from glaucoma can limit participation in valued occupations including engagement in reading. It has long been thought that mobility issues and glare sensitivity were the main factors that characterized glaucoma. In the late 1990s and early 2000s researchers began to examine quality of life (QoL) in those with glaucoma. It was during these early QoL studies that the first reports …

Adaptation To A Simulated Central Scotoma With Visual Search Tasks, Dave Walsh
All ETDs from UAB
This study characterized the perceptual and oculomotor adaptation to a simulated central scotoma in normally-sighted subjects and characterized the effects of two different scotoma profiles on the adaptation process. Twelve normally-sighted subjects, 6 for each type of scotoma profile, prac-ticed a search task (finding an "O" target among "C" distracters) for 11 blocks (162 trials per block). Search reaction time (RT) and eye movement data were collected. A head-mounted eye tracker was used to simulate two 10 deg circular central scotomas (CS), one with a sharp change from seeing to unseeing (S-CS) and the other with a gradual transition (G-CS). …
