PURPOSE To quantify the degree of association between juvenile myopia and parental myopia, near work, and school achievement. METHODS Refractive error, parental refractive status, current level of near activities (assumed working distance-weighted hours per week spent studying, reading for pleasure, watching television, playing video games or working on(More)
PURPOSE To assess the validity and reliability of the revised Convergence Insufficiency Symptom Survey (CISS) in adults aged 19-30 years. The CISS was developed to be the primary outcome measure for studies evaluating various treatments for convergence insufficiency (CI). METHODS CISS mean scores from adults with symptomatic CI and adults with normal(More)
OBJECTIVES The purpose of the study was to examine the effects of aerobic exercise on physiological fatigue (time on treadmill), dyspnea [rate of perceived exertion (RPE) and forced expiratory volume at 1 s (FEV1)], weight, and body composition in HIV-1-infected adults (200-499 x 106 CD4+ cells/l). DESIGN The study was a randomized, wait-listed,(More)
BACKGROUND The purpose of this report was to examine the relation between clinical tests and dry eye symptoms in patients with dry eye disease. METHODS Seventy-five patients with dry eye disease (ICD-9 code 375.15) were included in these analyses. There was no specific entry criterion for enrollment in addition to a previous dry eye diagnosis in this(More)
PURPOSE To identify whether parental history of myopia and/or parent-reported children's visual activity levels can predict juvenile-onset myopia. METHODS Survey-based data from Orinda Longitudinal Study of Myopia subjects from 1989 to 2001 were used to predict future myopia. Univariate and multiple logistic regression analyses were performed, and(More)
PURPOSE To apply interferometry as an in vivo measure of tear film thinning between blinks. METHODS Wavelength-dependent interference was used to measure the tear film thinning rates in 20 normal contact lens wearers, and spectra were captured at a rate of 4.5 per second for 20 seconds. Four recordings of precorneal tear film (PCTF) thinning were made,(More)
PURPOSE To evaluate refractive error, axial length, and relative peripheral refractive error before, during the year of, and after the onset of myopia in children who became myopic compared with emmetropes. METHODS Subjects were 605 children 6 to 14 years of age who became myopic (at least -0.75 D in each meridian) and 374 emmetropic (between -0.25 D and(More)
PURPOSE To evaluate accommodative lag before, during the year of, and after the onset of myopia in children who became myopic, compared with emmetropes. METHODS The subjects were 568 children who became myopic (at least -0.75 D in each meridian) and 539 children who were emmetropic (between -0.25 D and +1.00 D in each meridian at all visits) participating(More)
PURPOSE Accommodative insufficiency (AI) and convergence insufficiency (CI) have been associated with similar symptomology and frequently present at the same time. The severity of symptomology in CI has been linked to the severity of the CI, suggesting a dose-dependent relationship. However, with increasing severity of CI also comes increased comorbidity of(More)
PURPOSE The repeatability of individual dry eye diagnostic tests has been reported in the literature on normal samples of patients and to a lesser degree in dry eye patients. In this study, the repeatability of a battery of clinical diagnostic tests for dry eye was assessed on mild to moderate dry eye patients. METHODS A dry eye examination was performed(More)
