Alignment & Motility
Extraocular Movements
- Evaluates extraocular movement (big H)
- Checks convergence and accommodation (follows finger from far to near)
Extraocular Muscles and Direction of Movement
The extraocular movements of each are controlled by the 4 rectus and 2 oblique muscles
The extraocular movements may be tested by having the patient move the eye in the direction controlled by each muscle.
This may be accomplished by having the patient move their eyes in the six cardinal direction depicted on this diagram.
in all cases ocular trauma, ptosis, proptosis, neurological/endocrine department referral, endocrine, squint, strabismus we have to make this examination
Extraocular Movements
- Ask the pt to hold his/her head still and to follow your finger with their eyes
- Or ask him/her in certain direction
Six Cardinal Positions of Gaze
Convergence and Accommodation
-
Ask pt to focus on your finger held approx 12” away from his/her nose
-
Move your finger towards the pt’s nose
-
The eyes should converge and the pupils constrict (accommodation)
