purpose: to evaluate the effect of vertical prism induced stress on binocular visual evoked potentials. methods: using checkerboard stimulus patterns in two spatial frequencies (sfs) of 0.48 cpd as a low sf and 2.18 cpd as a moderate sf reversing with temporal frequency of 4 hz, the effect of increasing visual stress using vertical prisms of 0, 1, 2 and 3 prism diopters on binocular visual evok...

This work aimed to compare the visual patterns of under 16 (U16) athletes and professional basketball players. The sample was composed 10 U16 (aged 15.2 ± 0.4 years; 7.1 2.5 years experience) 27.6 3.7 18.4 4.6 All were males right-handed. Each participant performed 50 jump shots from different positions 5 angle (0°, 45°, 90°, 135° 180°). Number fixations, time first last fixation, total fixatio...
