Which test is used to assess stereoepisis?

The test used to assess stereoepisis is known as the Randot test. Stereoepisis refers to the ability to perceive depth based on the visual input from both eyes, and tests for stereo vision typically evaluate how well the brain can interpret images from slightly different perspectives.

The Randot test uses a series of images presented to both eyes with different patterns and angles to determine how well an individual can perceive depth. This is crucial for various daily activities that require depth perception, such as driving or sports.

On the other hand, the Wirt test is primarily a part of the Titmus test but does not exclusively assess stereo perception. The Snellen chart and LogMAR are tests designed to measure visual acuity, focusing mainly on how clearly a person can see letters or symbols at a distance, rather than depth perception. Therefore, the Randot test is specifically designed to assess stereoepisis effectively.
