Abstract: Diabetic maculopathy and especially advanced glaucoma are the most common eye diseases involving scotomas, blind spots in the visual field. The risk of having scotomas increases significantly with age and over 60 million people worldwide suffer from different forms of glaucoma of whom at least are half are not aware of the eye disease. One of the most common scotoma diagnosis tests is perimetry, a visual field test, which produces a complete map of the visual field, but may not be suitable for large screening of population. We are aiming to develop a new portable screening device for cost effective screening of eye diseases. We studied voluntary eye movement patterns evoked by Myller-Lyer illusion figure. Our study material included six scotoma patients (two with Maculopahia Diabetica, and four with Glaucoma simplex) and six control subjects. We recorded eye movement patterns with a portable Tobii T120 eye-tracker system on which a Müller-Lyer figure was projected. As a result, the va riation of the y-component of the eye movement trajectory indicates that the scotoma subjects had more vertical variation in their eye movement pattern than the control subjects (P< .01). The preliminary experiment suggests that further prospective studies using our method of analyzing eye movement patterns is warranted with larger sampale sizes and different types and stages of defects.
