What is Stereopsis Test

Stereopsis Test:Stereopsis is a test used to measure how well the eyes can work together.

The test involves the patient's ability to judge the depth of an object, or how far away it is.This test is done by using special glasses with prisms that will shift the images seen by each eye.

The patient is asked to look at an image and decide whether it is flat or 3-dimensional.The results of the test can be used to diagnose eye conditions such as strabismus (cross-eyed) or amblyopia (lazy eye).

It can also be used to measure the effectiveness of treatment and the ability of the eyes to work together.

When to do Stereopsis Test

  1. Stereopsis Test, also known as a stereo vision test, is a type of vision test that checks for binocular vision and depth perception. The test is usually performed on children aged 3 to 6 years old, as well as adults who have recently experienced changes in their vision, such as blurred vision, double vision, or a decrease in visual acuity.
  2. People at risk for developing amblyopia, strabismus, or other binocular vision disorders should also have a Stereopsis Test performed. This includes people who are nearsighted, farsighted, or have astigmatism. Additionally, people who have suffered a recent head injury or have had eye surgery should also have a Stereopsis Test done.
  3. It is important to consult a doctor urgently for a Stereopsis Test if you or your child experiences any sudden changes in vision, such as blurred vision, double vision, or a decrease in visual acuity. Additionally, if you or your child experiences any headaches, dizziness, or other vision-related symptoms, you should contact your doctor right away.

How Stereopsis Test is done

  1. The Stereopsis Test is a procedure that helps us to evaluate your depth perception. During this test, the patient will be looking into a special device that has two separate eye pieces, one for each eye. This device will present a series of different images to the patient's eyes. The patient will need to focus on the images while the device automatically records the responses of both eyes.
  2. The patient will be asked to indicate whether the images appear to be in 3D or 2D. The computer will then compare the responses of the patient's eyes and analyze the depth perception. Depending on the results, we can determine if any treatment or management is necessary.
  3. The Stereopsis Test is a simple and relatively quick procedure that can help us to monitor and diagnose any vision problems related to depth perception.

Absolutely love how understanding Dr. Kumud Raut is. The only place where I have not been told about only the process of getting a surgery, but rather they insist on educating about how the eye functions and the importance of having a healthy eye before any surgery.
