EOM testing
Muscle planes for primary action (ex) - ANS-*Right Eye*
Have pt look 23 degrees temporally
-puts OD in primary action plane
-allows us to evaluate the SR (when patient looks up) and IR (when patient looks down)
NOTE - ANS-Evaluation of the functioning of the extraocular muscles will involve
moving the eye into positions which will isolate primary action of each muscle
when you have patient move eyes 23 degrees temporal, you are evaluating what
muscles? - ANS-SR and IR
SR-when pt looks up
IR-when patient looks down
What nerve innervates SR - ANS-Oculomotor (CN III)
What nerve innervates IR? - ANS-Oculomotor (CN III)
When you have pt move eyes 51 degrees nasally, what muscles are you evaluating -
ANS-IO & SO
IO= when you look up
SO=when you look down
What nerve innervates IO? - ANS-oculomotor CN III
What nerve innervates SO? - ANS-CN IV (Trochlear)
move target straight laterally to evaluate the - ANS-LR
What nerve innervates the lateral rectus? - ANS-Abducens Nerve CN VI
Move the target straight nasally to evaluate the - ANS-MR
What nerve innervates the MR - ANS-oculomotor nerve (CN III)
