The present study obtained saccadic eye movements from 122 normal subjects to establish normative values and test-retest reliability data, using a recently developed electrooculographic recording and analysis system. Factors that might affect saccade values, such as age, sex, and time of day when testing, were also assessed. Mean (+/- S.D.) peak velocity values over saccade angles of 15 degrees...

Dyslexic and normal readers' eye movements were compared while tracking a moving fixation point and in reading. Contrary to previous reports, the dyslexic and normal readers did not differ in their number of saccades, percentage of regressions, or stability of fixations in the tracking task. Thus, defective oculomotor control was not associated with or a causal factor in dyslexia, and the dysle...

PURPOSE To create a binocular statistical eye model based on previously measured ocular biometric data. METHODS Thirty-nine parameters were determined for a group of 127 healthy subjects (37 male, 90 female; 96.8% Caucasian) with an average age of 39.9 ± 12.2 years and spherical equivalent refraction of -0.98 ± 1.77 D. These parameters described the biometry of both eyes and the subjects' age...
