Ma’am have you made a mistake in swinging flashlight test ? 3rd row RE you have written constrain consensually but it’s direct reflex only in right eye also. Please clear my doubt. Time3:35
When we carry out a swinging flash light test, we are conducting both direct and indirect test together . But yes the labelling in the book is wrong, the RE is showing construction due to the direct reflex and the left eye is showing constriction due to indirect/ consensual response.. I hope that is clear😊

Wow, I have been looking for an understandable explanation on RUclips for half a day now. Could not find one that explained it so clearly. Thank you so so much. This is the epitome of a good teacher. Thank you.
Madam thank for your explanation I am a big fan of you but this video have 2 mistakes first was Rt and Lt eye mismatch in explaining swinging light test Second was during reverse RAPD test From what I know reverse RAPD was examiner artifact test that occour when examining total blind eye and normal eye So reverse RAPD can be used in cases of complete blindness in one eye (e.g., no light perception) to confirm the lack of any afferent input from the blind eye.Also to Avoid misinterpreting the findings during a standard RAPD test, which could lead to confusion.
Hi Abhishek! From what I understood from your question; I think you are asking about the efferent and afferent status in RE In RE both are affected.. To understand this we have to also understand the pupillary pathway. Each afferent limb has two efferent limbs, one ipsilateral and one contralateral. The ipsilateral efferent limb transmits nerve signals for direct light reflex of the ipsilateral pupil. The contralateral efferent limb causes consensual light reflex of the contralateral pupil. So here the RE Efferent is affected so no direct reflex. Now we need to check if afferent is also affected or not? For this we rely on the other eye consensual response.. If the other eye consensual is absent, it means either the RE afferent is defective or LE efferent. ( You can exclude LE efferent defect as the pupil is nicely constricting to direct light...right? So it means we have a RE afferent defect !

You're very welcome!
Most comprehensive video on RAPD 😊 Thank you ma'am

Second was during reverse RAPD test
From what I know reverse RAPD was examiner artifact test that occour when examining total blind eye and normal eye
So reverse RAPD can be used in cases of complete blindness in one eye (e.g., no light perception) to confirm the lack of any afferent input from the blind eye.Also to Avoid misinterpreting the findings during a standard RAPD test, which could lead to confusion.
Thank you for sharing :)
@@InsightOphthalmology Also thank you for your hard work I appreciate it very much
Please Keep educate us ❤
You're welcome! Thank you for your support:)
Best video 👍
Left eye Right eye mismatch is there in the explanation vs the image that has been put up in the swinging light test slide
At what timing?
Was looking for this comment. She switched it up. It is clearly written that the LE is normal and the RE has the defect
Thankyou so much TT thanks alot. I was soo confused
Glad it helped!
Thank you thank you and thank you ❤❤❤❤❤❤❤
In reverse RAPD if RE has efferent defect and intact afferent why stimulation from RE will be less to the left side during concensual light refelx??
Hi Abhishek! From what I understood from your question; I think you are asking about the efferent and afferent status in RE
In RE both are affected..
To understand this we have to also understand the pupillary pathway.
Each afferent limb has two efferent limbs, one ipsilateral and one contralateral. The ipsilateral efferent limb transmits nerve signals for direct light reflex of the ipsilateral pupil. The contralateral efferent limb causes consensual light reflex of the contralateral pupil.
So here the RE Efferent is affected so no direct reflex. Now we need to check if afferent is also affected or not?
For this we rely on the other eye consensual response..
If the other eye consensual is absent, it means either the RE afferent is defective or LE efferent.
( You can exclude LE efferent defect as the pupil is nicely constricting to direct light...right?
So it means we have a RE afferent defect !
Thankyou sooo much mam
Good lekcher
Epic explanation mam👍👍👍
In Marcus Gunn pupil is accomodation intact ??
Kkkkkko
