Final answer:
Disturbances in voluntary gaze refer to abnormalities or problems in controlling and directing eye movements intentionally. One example is internuclear ophthalmoplegia, causing double vision. Testing eye movements can help diagnose these disturbances.
Step-by-step explanation:
Disturbances in voluntary gaze refer to abnormalities or problems in controlling and directing eye movements intentionally. These disturbances can occur due to various factors such as damage to the eye muscles, brainstem, or neural pathways involved in eye movements. One example of a disturbance in voluntary gaze is internuclear ophthalmoplegia, where one eye fails to abduct while the other eye adducts properly, leading to double vision. Testing eye movements can help diagnose these disturbances by evaluating the ability to track and control eye movements using visual stimuli.
