Research Abstract

1) Software programed in MATLAB was developed for analysis of horizontal, vertical and torsional eye movement that was extracted from a sequence of captured images of anterior ocular segment. Small eye movement in superior oblique myokymia could be evaluated with this software.
2) Compact video image analysis system that provided measurement of eye movement in three-dimensional (horizontal, vertical and torsional component) and photographing system with high-resolution camera that provided taking images in complete dark room were developed for analysis of eye movement in normal subjects and patients with strabismus.
3) Ocular alignments assumed center position by human patients with strabismus were measured in complete dark room. Difference in ocular dominant between the hole-in-the-card test and ocular alignments assumed center position was indicated. More accurate method was needed for analysis of ocular alignments assumed center position.
