The fly stereo test, also known as the Randot stereotest or fly stereogram, is a visual assessment tool used to evaluate an individual's depth perception and stereopsis (perception of three-dimensional depth). It is commonly administered during eye examinations, especially for children, to assess binocular vision and detect any impairments or abnormalities.
The test consists of a series of images or patterns that are designed to create a perception of depth when viewed with both eyes. These images typically depict simple shapes, such as circles or squares, arranged in different orientations or disparities. The test utilizes the principle of binocular disparity, which is the difference in perspective seen by each eye, to create the perception of depth and allow for stereoscopic vision.
During the fly stereo test, the individual wears polarized glasses or utilizes a device that separates the images seen by each eye. They are instructed to identify specific patterns or shapes that appear to stand out or pop out in three dimensions. The ability to perceive the stereoscopic effect indicates the presence of binocular vision and normal depth perception.
The fly stereo test is particularly useful in detecting and assessing binocular vision disorders, such as strabismus (misalignment of the eyes), amblyopia (lazy eye), or other conditions that may affect depth perception. If an individual is unable to perceive the three-dimensional effect or struggles to identify the shapes correctly, it may indicate a potential issue with binocular vision.
The results of the fly stereo test help eye care professionals diagnose and monitor binocular vision disorders, guide treatment decisions, and track progress during vision therapy or other interventions. It is an essential tool for evaluating and managing conditions that affect depth perception and stereopsis.
Overall, the fly stereo test is a valuable assessment tool that allows eye care professionals to evaluate an individual's depth perception and binocular vision abilities. By detecting and addressing any impairments or abnormalities in stereopsis, appropriate interventions can be recommended to optimize the individual's visual function and overall visual experience.

Very Informative. But how do we go about recording the results? Is there a PDF sheet online to print off?

[@optometryreels]

You can score based on the finest symbol which patient pointed correctly.. The values of that will be mentioned at back of the chart or it will come along with the test.

Do I need to do the animal pictures, even when the patient gets all the fine circle one?
