EOM and Pupil testing
Annulus of Zinn - ANS-Origin of the 4 rectus muscles
Primary action planes - ANS-Ability to isolate muscles
23 degrees temporal
51 degrees nasal
23 degrees temporal up - ANS-Superior rectus
CN III
23 degrees temporal down - ANS-Inferior rectus
CN III
51 degrees nasal up - ANS-Inferior oblique
CN III
51 degrees nasal down - ANS-Superior oblique
CN IV
Temporal muscle - ANS-Lateral rectus
CN VI
Nasal muscle - ANS-Medial rectus
CN III
What angle do you use for version - ANS-30 degrees
Angle Kappa test - ANS-Monocular
Reflection of penlight should be slightly nasal in pupil
Normal finding +0.5mm
Hirschberg test - ANS-Binocular
Reflection of penlight in both eyes should be slightly nasal in pupil
Normal finding +0.5mm OU
Abduction - ANS-Rotation of eye away from midline
Adduction - ANS-Roataion of eye toward midline
