RANDOT Stereo Test

RANDOT Stereo Test

PRODUCT OVERVIEW

The Randot Stereo Test is a clinically validated eye examination that measures stereopsis, also known as depth perception. It evaluates how well both eyes work together to see three-dimensional detail. Eye specialists use this test worldwide as part of a comprehensive binocular vision assessment. Because the test uses random dot patterns instead of simple line drawings, it provides a more accurate measurement of true depth perception.

In clinical practice, this test helps detect subtle binocular vision problems that may not appear during a standard visual acuity check. As a result, it supports more precise diagnosis and treatment planning.

HOW THE RANDOT STEREO TEST WORKS

During the Randot Stereo Test, the patient wears polarized glasses and looks at special test images made of random dots and shapes. These images appear flat at first glance. However, if both eyes coordinate properly, hidden shapes appear in depth.

The test presents targets with different levels of disparity. Therefore, the examiner can measure stereo vision in seconds of arc and determine how fine the patient’s depth perception is. The procedure is noninvasive, quick, and comfortable for both children and adults.

WHO SHOULD TAKE THIS TEST

This test is recommended for patients who need accurate depth perception assessment. For example, it is useful in the evaluation of:

1. Children with suspected strabismus or amblyopia
2. Patients with double vision or poor eye coordination
3. Candidates for refractive or cataract surgery
4. Individuals with learning or reading difficulties related to binocular vision
5. Patients under binocular vision therapy or follow-up

CLINICAL VALUE AND ACCURACY

The Randot Stereo Test is supported by long-standing clinical use and peer-reviewed research in binocular vision testing. Because it uses random dot stereograms, it reduces guessing based on monocular clues. Consequently, results more closely reflect true binocular depth perception.

Eye care professionals often combine this test with other ocular alignment and motility tests. Together, these measurements provide a more complete picture of functional vision.

WHAT PATIENTS CAN EXPECT

The test usually takes only a few minutes. First, the examiner explains the task in simple terms. Next, the patient identifies shapes or symbols that appear raised or recessed. No eye drops, injections, or contact instruments are required. Therefore, patients can immediately return to normal activities after testing.

Patient cooperation improves accuracy, so clear instructions are given before the test begins.

SAFETY AND LIMITATIONS

The Randot Stereo Test is safe and risk-free. However, results may be limited in patients with very poor vision in one eye, dense cataract, or active ocular disease. In such cases, the doctor may recommend additional tests. Clinical findings are always interpreted in the context of a full eye examination.
