Human Eye Location for Quantifying Eye Muscle Palsy

چکیده
We describe a system for measuring the angle of eye gaze error on people with a squint. The program to analyse an eye image models each eye simply as a circular iris within a sphere rotating about its centre. A combination of edge detection, image transformation and template matching are then used to best fit the model to the image of the eye. The algorithm behaves correctly on 95% of eye images, over a range of gaze directions of ±30° horizontally and ±25° vertically, and enables the overall system to achieve a useful level of accuracy.

Adaptive neural mechanism for Listing's law revealed in patients with sixth nerve palsy.
PURPOSE During fixation and saccades, human eye movements obey Listing's law, which specifies the torsional eye position for each combination of horizontal and vertical eye positions. To study the mechanisms that implement Listing's law, the authors measured whether the law was violated in peripheral and central unilateral sixth nerve palsy. METHODS Twenty patients with peripheral (13 chronic...
متن کاملDynamic aspects of trochlear nerve palsy.
Trochlear nerve palsy leads to kinematic aberrations of both the paretic and the unaffected eye. During dynamic head roll, the rotation axis of the covered paretic or unaffected eye deviates inward, while the rotation axis of the viewing paretic or unaffected eye aligns with the line of sight; this convergence of rotation axes increases with gaze moving in the direction of the unaffected eye. D...
متن کاملAdaptive neural mechanism for listing's law revealed in patients with fourth nerve palsy.
PURPOSE During fixation and saccades, human eye movements obey Listing's law, which specifies the eye's torsional angle as a function of its horizontal and vertical position. Torsion of the eye is in part controlled by the fourth nerve. This study investigates whether the brain adapts to defective torsional control after fourth nerve palsy. METHODS Thirteen patients with fourth nerve palsy (1...
متن کاملMonte Carlo simulation of two 106Ru eye plaques in a new mathematical human eye model
BEBIG Ruthenium-106 ophthalmic plaques have been used for treatment of uveal melanoma, retinoblastoma, melanoma of the iris and other special applications for many years. The plaques consist of a thin film of 106Ru, a beta emitter, encapsulated in pure silver. The present work proposes a new mathematical eye model for ophthalmic brachytherapy dosimetry. This new mod...
متن کاملStudy of Optical Models Regarding the Human Eye
Introduction: Until now, many models have been presented for optical study of the human eye. In recent years, surgery on the anterior section of the eye (such as cataract and photo-refractive surgery) has increased, so a study on the optics of the eye and evaluation of vision quality has become more important. Material and Methods: In this article, some of these models are considered. They incl...
