Social Accountability: Introducing A New Dimension In Optometric Education, Vanessa Raquel Moodley, James Loughman, Kovin Naidoo

Articles

Optometry globally has undergone major developments yet poor eye health statistics remain. The World Health Organization (WHO) cites social accountability as key to addressing health challenges, urging the education sector to be more socially accountable and train according to the needs of society. A qualitative, descriptive study was used to determine the integration of social accountability within optometric education in sub-Saharan Africa. Eleven academic leaders and two student groups participated in key stakeholder interviews and focus group discussions respectively. Data was thematically analysed using interpretive content analysis. The study found that social accountability policies or practices were not formally integrated …

Physical Activity For Adults With Visual Impairments: Impact Of Socio-Demographic Factors, Justin A. Haegele, Xihe Zhu, Jihyun Lee, Lauren J. Lieberman

Human Movement Studies & Special Education Faculty Publications

Little is known about what factors influence physical activity participation for adult-aged individuals with visual impairments. Therefore, the purpose of this study was to explore the impact of socio-demographic factors on the physical activity participation of adults with visual impairments. The international physical activity questionnaire-short form and a socio-demographic factor questionnaire were distributed to individuals with visual impairments. A total of 176 adults (M_age = 47.04, 52.8% female) completed the questionnaires. Physical activity and socio-demographic variables were analyzed descriptively and relationships were explored using correlation analysis and multiple regression analysis. On average, participants reported 413.79 minutes of moderate-to-vigorous physical …

The Impact Of Soft Cl Wear On Corneal Curvature And Thickness And On The Outcomes Of Refractive Laser Surgery, Aoife Lloyd Mckernan

Doctoral

Introduction: Soft CL (SCL) wear can alter the cornea and have significant effects on vision quality (Hardten and Gosavi, 2009; Pflugfelder et al., 2002; Ryan and Jacob, 1996; Tseng et al., 2007). This may have implications for visual outcomes following corneal refractive surgery (CRS) (Tang et al., 2005). The time required for resolution of these SCL-induced changes can vary (González-Méijome et al., 2003a; Hashemi et al., 2008; Ng et al., 2007; Nourouzi et al., 2006; Schornack, 2003; Wang et al., 2002b). Despite this, current guidelines relating to cessation of SCL wear prior to CRS vary greatly, and are lacking in …

Large Reductions Are Possible In Older Driver Crashes At Intersections, Siby Samuel, Yusuke Yamani, Danald L. Fisher

Psychology Faculty Publications

Among all crash types, the largest percentage of older driver fatalities occur at intersections. Many explanations have been offered for older drivers' increased risks of crashing at intersections; however, only recently was it determined that older drivers were much less likely to glance for latent threats after entering an intersection than middle-aged drivers. In response, training programmes were designed to increase the frequency of such glances. The programmes have proven effective, doubling the frequency of these glances for up to a period of two years post-training. The programmes take only an hour to administer and are not directly targeted at …

Chromatic Sensitivity: A New Insight Into Color Discrimination, Micah Jason Kinney

All ETDs from UAB

Color discrimination varies between individuals even in the absence of a congenital color vision defect. Attempts to explain this variation have shown no link to macular pigment optical density, L:M cone ratios, non-verbal IQ, or female carriers of color vision deficiencies. This study examined individuals’ relative luminance and color-opponent systems sensitivity to their Farnsworth-Munsell 100-Hue (FM-100) color discrimination ability. Thirty normal color vision subjects performed FM-100 and increment threshold testing for white, blue, green and red on a 150 cd/m2 white background. White increment thresholds were compared to colored increment thresholds to produce a luminance to color-opponent system sensitivity ratio …

Histopathology And Image Validation Of Outer Retinal Tubulations In Age-Related Macular Degeneration, Katie M. Litts

All ETDs from UAB

High-resolution imaging of the retina using spectral domain optical coherence tomography (SD-OCT) and adaptive optics scanning laser ophthalmoscopy (AOSLO) is revealing new information about photoreceptor degeneration in age-related macular degeneration (AMD) and other diseases impacting rod and cone photoreceptors. By SD-OCT, the hyperreflective outer retinal bands are visible due to the precise vertical compartmentalization and horizontal alignment of outer retinal cells and tissues (Müller cells, photoreceptors, RPE, and Bruch’s membrane). Validating these bands with normal eyes is difficult because the outer retina is very delicate making accurate histology requiring attached retina and vertically aligned photoreceptors challenging. Conversely, the bands are …

Elementary Photoreceptor Signaling In Human Vision, Kady Scarlett Bruce

All ETDs from UAB

To perceive a spot of light at photopic threshold, a minimum number of photons must be absorbed by cone photoreceptors. While many factors affecting psychophysical threshold have been studied, few have been examined at the single-cone level. Here we reveal how variation in synaptic weighting and signal integration among cones in the human retina occurs in vivo. Using an adaptive optics scanning laser ophthalmoscope (AOSLO) equipped with stimulation capabilities, we targeted cone-sized stimuli to single cones. Perceptual increment thresholds were measured from individual cones and cone pairs in 7 subjects using a Bayesian-based staircase method of threshold estimation. In 42 …

Efficient In Vitro Development Of Photoreceptors From Human Pluripotent Stem Cells, Joseph C. Reynolds

Dissertations, Masters Theses, Capstones, and Culminating Projects

Degeneration of the rod and cone photoreceptors in the human retina is among the most common causes of blindness. Replacing these damaged photoreceptors may help to restore vision. Repairing the damaged retina relies on the insertion of new, healthy cells. Embryonic stem (ES) cells and induced pluripotent stem (iPS) cells are two possible sources of photoreceptors to restore vision. Previous data shows that human ES cells and iPS cells can be differentiated into photoreceptors and transplanted into the eye to restore some vision. However, this process is inefficient, and costly. Here, we show a new method for inducing photoreceptor production …

Macular Pigment Spatial Distribution Effects On Glare Disability, Christopher Putnam, Carl Bassi

College of Optometry Faculty Works

Purpose This project explored the relationship of the macular pigment optical density (MPOD) spatial profile with measures of glare disability (GD) across the macula. Results The cHFP identified reliable MPOD spatial distribution maps demonstrating a 1st-order exponential decay as a function of increasing eccentricity. There was a significant negative correlation between both measures of foveal MPOD and GD using 6cycles per degree (cpd) and 9cpd stimuli. Significant correlations were found between corresponding parafoveal MPOD measures and GD at 2 and 4° of eccentricity using 9cpd stimuli with greater MPOD associated with less glare disability. Conclusions These results are consistent with …
