test that measures the ability to hear different sounds

a test that determines a patient’s ability to perceive sensation

test in which the patient, with eyes closed, identifies an object placed in one hand by the physician

test in which the patient is instructed to close the eyes and identify a number or letter written on the hand with a pen

test in which the patient lies supine with eyes closed and identifies an object as “sharp” or “dull” when the object is pressed against the skin

chronic disorder of the labyrinth of the inner that causes vertigo, or a sensation of spinning

form of strabismus in which one or both eyes turn inward

common condition in which small specks, squiggly lines, or hair-like strands appear in the field of vision due to shrinkage and detachment of collagen fibers in the vitreous humor

form of strabismus in which one or both eyes turn outward

misalignment of the eyes caused by weakened eye muscles; also known as crossed eyes
