Stereoscopic Vision and Depth Perception Testing

Stereoscopic vision and depth perception testing is important in identifying diseases such as Amblyopia, Strabismus, Suppression and Stereopsis. Stereovision is how each eye may see an object from different angles, but combines these angles to give us a 3D image. There are many stereoscopic/depth perception tests on the market; some are geared more for children while others to adults. Many of these tests ask the patient to identify the “raised” letter, shape or animal to measure depth perception and identify if the patients eyes are working together to identify the intended image. These tests offer intriguing subjects to interest various patients. An Ophthalmology practice should have a variety of these tests on hand if serving patients of varying ages.

The Stereo Butterfly tests and evaluates random dot stereo depth perception for both gross stereopsis (2500 to 1200 seconds of arc) and fine depth perception. The figures present on the test cannot be identified without viewing glasses.

Features:

The Distance Randot® Stereotest is the ideal tool for the eyecare professional who deals with strabismus, amblyopia, and intermittent exotropia.  This test helps detect abnormalities in distance stereopsis and thus can give an earlier indication of 		Designed specifically for use with children ages 3 and up. The patient is asked to distinguish between a "Raised E" and a non stereo target.
