Bagolini test is described as:

Bagolini test is described as:

• A. A test for color vision.
• B. A test of ocular motility.
• C. A binocular test that uses thin lines to assess fusion and suppression with minimal dissociation.
• D. A test for refractive error.

Answer: (C)

It tests how the two eyes fuse visual input under nearly natural viewing conditions and detects suppression. The Bagolini test uses special lenses that produce two very thin, faint lines when you look at a single light source. Because the stimulus is minimally dissociating, a person with normal binocular vision will report a single, fused line, meaning the lines from both eyes align into one percept. If the eyes are misaligned, the lines may appear in different positions, revealing the deviation. If one eye is suppressed, the patient may only perceive the line from the seeing eye. This setup makes it especially useful for evaluating sensory fusion and detecting suppression or anomalous correspondence, without testing for color vision, eye movements, or refractive error.
