Abstract
Flicks in one or both of eyes are measured by a sensor (1) employing a limbus reflection method. An output of the sensor is applied to and digitized by an A/D converter (2). The digitized output is applied to a computer (3). The computer calculates flicks data of eyeballs, then calculates fractal dimension simultaneously or individually in a time-elapsed manner or for a definite time period, and quantifies characteristics of the eyeball control systems from the value of the fractal dimension or the time dependence of the fractal dimension.
Claims7
A method for analyzing small oscillations of an eye to enable quantifying said small oscillations, comprising the steps of:
- measuring small eye oscillations while an eye of a subject is looking at a target and providing output signals corresponding thereto, said small eye oscillations having small amplitudes;
- converting said output signals to digital signals;
- inputting said digital signals to a computer;
- calculating fractal dimension for said measured small eye oscillations using said digital signals;
- providing a quantity using said fractal dimension which corresponds to said small oscillations of the eye;
- and
- displaying the quantity on a display means,
- using said quantity to accurately model an eyeball control system.
