Abstract

There are six muscles responsible for ocular movement: medial rectus, lateral rectus, superior rectus, inferior rectus, and superior oblique and inferior oblique. The spiral of Tillaux is an imaginary line that connects the insertions of the four tendons of the rectus muscles to the corneal limbus. The movements of the ocular globe are carried out according to the so-called three axes of Fick. Each ocular muscle gives rise to different functions. Ocular movements can be divided into monocular movements and binocular movements. The dynamics of the ocular movement are guided by ocular motility laws. Over the years many techniques has been used for registering ocular movements such as electrooculography and other photoelectric techniques, recently 3D-VOG (video-oculography) is been used. The use of video-oculography in analyzing ocular motility is fundamental, given that the cycloduction analysis often reveals situations that are very difficult to analyze. It is used in analyzing strabismus, analysis of dissociated strabismus; dissociated vertical divergence. It is also used in diplopia analysis, analysis of muscular paralysis, Duane´s Retraction Syndrome. The study of nystagmus is a problem that up to now we have not been able to offer a definite solution, perhaps because we are not able to fully understand the complications of its mechanisms, but with the help of video-oculography we can begin to study its analysis in depth and perhaps we are at the beginning of a new era both in the analysis of nystagmus as in strabismus in general.
