Abstract
The present multi-functional, visual test instrument is realized by integrating miniature, close-proximity displays, such as LCDs, with viewing optics, which is constructed in the form of preferably a unitary housing. In a preferred embodiment, the multi-functional, visual test instrument includes two viewing assemblies, and displays, which are all enclosed in the housing that is slidably or pivotally attached to a movable mount, such as a slit lamp base. In operation, various optical test objects or stimuli are viewed by the patient on the displays through the viewing assemblies. The shape, size, speed, frequency, location, color, contrast and intensity of the test objects or stimuli are computer generated. A hand operated switch, mouse, joystick, or other input means, may be used for the patient to respond to the observed test objects or stimuli.
