In dextroelevation, the abduction is carried out by the lateral rectus? And then in the abducted eye, the superior rectus causes elevation?
Or the entire movement (abduction+elevation) is by the superior rectus?

Yoke:
During Abduction: Vertical Movement Primary by Recti.
During Adduction: Vertical Movement Primarily by Obliques.

Good job bro😊😊

@@aleemkhan320 thanks.

[@shreyag9366]

But the inital abduction/adduction is by the horizontal recti?

[@ophthalmologypearls]

it depends. if the initial movement is say abduction, then the elevation will primarily be by the superior rectus. if the eyes move into dextroelevation directly from the primary position, then a combination of muscles act simultaneously to bring about this movement

[@shreyag9366]

@@ophthalmologypearls But if this movement occurs from a combiantion of muscles why do we use it to test the superior rectus (in H test) and why is action mentioned as only by superior rectus and inferior oblique?

[@haydenyip1412]

I am super confused. Superior and inferior oblique muscles are responsible for abduction movement; superior and inferior rectus muscles are involved in adduction, but why they will be involved in the opposite movement here? For example, 2:43 mins, should it be left inferior muscle and right superior muscle innervated?

[@ophthalmologypearls]

So here we are talking about dextrodepression
So right eye will be in abduction - best depressor will be inferior rectus (so right inferior rectus)
Left eye is in adduction - best depressor is superior oblique (so left superior oblique)
Abduction & adduction are tertiary actions of these muscles. What we are talking about here is the single most muscle which has the main action in a particular position

@@ophthalmologypearls Thankful for your source, I would spend some time to think about the motions of muscles in my head to really understand it, but in the meantime, I would just memorize it by rote for my assessment. Thanks for your videos about extraocular muscles and gaze position, I personally think you explain it easier and more in-depth with your stereoscopic model than my optometry teacher. Many thanks. ☺️
