MARYVILLE 612 EXAM 1 2024 WITH 100% CORRECT ANSWERS How do you test EOM? - correct answer Eye movement is controlled by 6 extraocular muscles and 3 cranial nerves, III, IV, and VI. To evaluate eye movement, use 4 techniques. ● First have the patient watch your finger move through the 6 cardinal fields of gaze. Jerking or sustained nystagmus is abnormal. A few beats of horizontal nystagmus may occur. ● Second have the patient follow your finger vertically from the ceiling to the floor.The globes and the upper eyelids should move smoothly without eyelid lag or exposure of the sclera. ● Third, test extraocular muscle balance using the corneal light reflex. WIth the patient looking at a nearby object, shine a light on the nasal bridge. The eyes should converge and reflect the light symmetrically. ● Fourth, if the corneal light reflex is imbalanced, perform the cover-uncover test. As the patient stares at a fixed point nearby, cover one eye and observe the uncovered eye. Then remove the cover and observe that eye as it focuses on the object. Note any eye movement. Your patient should be able to follow your finger with full, smooth extraocular movements and without nystagmus, or "shaky" eye motion. Normal extraocular movements indicate intact cranial nerves III, IV, and VI. *******What is the difference between objective and subjective data?
