What is the h test of eyes?

The H test of eyes is a simple clinical examination used to assess ocular motility and the function of the extraocular muscles. During the test, the patient is asked to follow a visual target in the shape of an "H" pattern, which helps evaluate the movement of the eyes in different directions. This test can help identify any abnormalities in eye movement, such as strabismus or cranial nerve palsies. It's often performed in an eye examination or neurological assessment.
