Abstracts labor. I compiled article information and will synthesize literature results. This research will lead into a plan for deciding on the most effective practices and treatments, as well as areas for future work and improvements with regard to the available resources in underdeveloped countries.

Intraocular scatter from anterior optics and subsequent glare is one of the more prevalent forms of visual disturbance in adults and is a significant cause of automobile accidents in the US. This scatter forms a normally distributed intensity curve (the point-spread function), which can be measured. For example, two point sources of light produce two incident rays whose intensity curves may overlap, causing a subject to only perceive one light source (the Rayleigh criterion). The purpose of this experiment is to establish this two-point threshold as a measure of hyperacuity related to intraocular scatter, and to determine the contribution of both wavelength and intensity to that scatter. Emmetropic (20:20 uncorrected, Snellen notation) participants were recruited from the UGA student population. Two-point thresholds were determined using a broadband xenon light source, presented as two independent points whose distances from each other could be adjusted. Intensity of the source was varied during testing, and narrow-band interference filters were used to change the chromatic content of the stimulus. It is anticipated that two-point threshold distances and light intensity levels are inversely related due to increased levels of intraocular scatter at high luminance levels. These results will be used to inform the testing of novel contact lens technology, which may absorb the wavelengths of light most prone to scatter.

Medication adherence is a significant concern for solid organ transplant candidates, parents and healthcare providers. Barriers to medication adherence have been related to treatment barriers (e.g., hospitalization, rejection episodes, and death) and internalizing symptoms in children and adolescents who have received solid organ transplants. Little research has been done to explore the association between medication adherence and psychosocial functioning (e.g., anxiety, depression, and attention problems) among adolescent patients before they receive their transplant. The purpose of this study is to examine medication adherence and psychosocial functioning among pediatric candidates awaiting solid organ transplants in order to prevent treatment barriers. The population includes 35 adolescents ranging from ages 12-20 (M= 15.99, SD= 2.35) awaiting solid organ transplants (54.3% kidney, 22.9% liver, and 22.9% heart). Participants were recruited at the Transplant Services Clinic at Children’s Healthcare of Atlanta. Participants completed self-report measures on psychosocial functioning and barriers to adherence using paperand-pencil measures while at their pretransplantation evaluation appointment. Total barriers to medical adherence were positively correlated with attention problems (r=.34, p=.05) and depression (r=.56, p<.001). Correlations between barriers and anxiety and hyperactivity were not significant. Significant between-organ group differences in barriers to adherence were also found between kidney recipients (M=44.10, SD=36.75) and heart recipients (M=31.88, SD=39.63). Identifying the significant relationship between psychosocial functioning and barriers to medication can help prevent treatment barriers
