The Eye Cube Stereo Vision Test serves as a valuable diagnostic device for Stereo and Binocular Vision evaluation in children and adults. It can also prove to be an effective diagnostic screening aid for children when administered in a school Vision Screening Program. The Eye Cube Vision Test is viewer free and no special 3-D glasses re needed to view the test.

The Random Dot Stereograms presented here are powerful tools for the study, testing and training of Binocularity, Stereopsis, Visual Attention, Form and Depth Perception. The remarkable feature of these Stereograms is that the images seen are void of all monocular cues to form and depth. If adequate visual attention is present, the form and depth relations perceived are based solely on the retinal disparities created in an intact binocular visual system.

Thus, these Random Dot Stereograms provide a foolproof method of assuring the binocularity of a patient. For an individual viewing

The stereograms, correct interpretation will be possible if and only if both eyes are open and working properly together. If a correct response is not achieved within 30 seconds, we can assume some binocular visual problem exists for the patient.

The Eye Cube contains 4 side panels, 3 of which contain a single random dot figure, the fourth is blank and serves as a control. To administer the test, the Cube is presented properly oriented (nameplate on top) for identification of the figures within the side panels. Each panel of the Cube must be viewed straight on. Proper viewing distance is 12-16 inches from the patients eyes. The Eye Cube can be held either by the patient or the examiner, but care must be taken to hold the Cube still and not tilt it. Assymetrical viewing of the Cube may cause the images to appear in reverse depth. After the figure in one panel is identified, the Cube is turned or rotated to present another panel for identification. The nameplate should always remain on top. In each panel the random dot figure normally hidden will appear to rise and float in space off the background.

The Eye Cube has been designed to test for gross binocularity and stereopsis quickly and efficiently. A single verbal identification of the random dot figure with a panel will suffice and will instantly provide the examiner with a wealth of information about the patient's binocular vision status.

As stated above, 3 of the 4 side panels contain a single random dot figure. One panel contains a square, one panel contains a circle, and one panel contains the letter E. The examiner should verify which particular random dot figure he is presenting be either viewing it directly or be referring to the tope nameplate where one number from 1-4 appears along each edge of the top plate. These numbers serve to identify the random dot figure contained in the side panel below it as follows: Beneath # 1 is the E, beneath #2 is the circle, beneath #3 is the square and beneath #4 is the blank.

For non-verbal patients the figures perceived can be matched against the corresponding simulated 3-D perspective drawing of each of the random dot figures presented in the instruction card.
