This is the most comprehensive video I’ve seen on Squint assessment! Thank you for sharing! Watching from Zambia 🇿🇲

Best video ever on strabismus. so easy to follow along with ur teaching. you are a very good teacher, hats off to you!! please continue to uploaddd more

This was absolutely amazing. I don't think I have gotten such knowledge even in Prepladder subscription. Thank you!

From an article on measuring deviation in a group of patients: The grading system used in this study was originally proposed by Zipf and further developed by Wright et al.3 Fixation prefer- ence was classified into 5 categories: (0) no fixation - will not hold fixation with the nonpreferred eye after the oc- cluder is removed from the preferred eye with immediate fixation to the preferred eye; (1) holds with difficulty - fixates with the nonpreferred eye momentarily but loses fixation instantly; (2) holds fixation briefly - holds 2 to 3 seconds with the nonpreferred eye when the cover is re- moved from the sound eye; (3) holds well - holds fixation almost all throughout a blink time before refixation to the dominant eye; and (4) freely alternates fixation with no preferred fixation with either eye.

in the books its given do alternate cover test after cover and uncover test , and alternate cover test is to detect total deviation - doesn't distinguish between phoria and tropia..

This is an amazing and comprehensive video ever seen in my life. Thanks for your hard work.

Good... Very good..... We wants more video from Dr. Babita chanel.... On different topics

Osm lecture mam

Thank youiui❤❤❤❤

one question---at 22;44 , if there 6th cranial palsy on the left side and the eye is already deviated nasally, when you do the cover test and occlude the right eye, which muscle pulls the left eye to midline ?

awesome teaching

Maam how to check whether eye having eccentric fixation or Abnormal retinal correspondence ARC through worth 4 . Test? And for palsy and contracture?

nice presentation madam

Thank you mam

Thank you

22:40 The secondary deviation can only be assessed when the fixation behavior is grade 0, right ?

Pls how do you determine when a patient is using eccentric fixation and is also having gross restrictions of eom?

Mam agr pt ko left eye mai exotropia h and on alternate cover test agar both eyes out to in arai h and right eye up to down then kia ye alternate exotropia h with left dominance and right eye mai hyperphoria hga ya hypertropia????

Hi can this be done without translucent occluder?

Please make a video for removing of squint in exercise type of way

Just wow.

GREAT

Plzzz make video on krimsky corneal reflex test

Why do we need fixation target for near and distant ?

Wonderful lecture yet again Dr Babita. Can you please make a video on refractive errors and also another video on intermittent squints also?

Mam how to treat Alternate exotropia about 15 degree kindly suggest best way of treatment.

Please one video of Acc and non Acc Esotropia

Kindly do a video on intermittent oesotropia

I appreciate your video.... I would like to add one point as per the latest literature whn we perform HBT.... 1 mm of deviation is equal to 11.8 degree.

How to exclude eccentric fixation?

Best

Hi Mam, Your videos are very helpful I need advice on my son's eyes ...he is going to be 2 year by this Nov... Need urgent help 🙏 Can you suggest if we can connect online? Also I am based in Hyd Me and my Wife will be highly thankful to you for same

Madam, do both normal and squint eye try to fixate in alternate cover testing and we can say which eye has squint only after repeated alternate cover testing when squint becomes manifested?

On 14:25 , you say that one of the pre requisites for performing cover uncover test is "central fixation in both eyes" .. so how can we determine this before doing the cover uncover test if the eye is centrally fixating or not ? Any test for this ?

Iam completed optometry Which course best madam

Thank you once again for yet another well detailed tutorial. But please how do we correct abnormal posture(if present) before continuing with the cover test, considering that the patient has become accustomed to the position, and will always maintain such position even unconsciously?

19:04 or before : does Alternating squint appear as Latent squint ?

22:36 1)you said that left eye moves out to take fixation but how is it going to fixing becoz fixing done with the help of left lateral rectus but it is paralyzed in this case then how can left eye moves out ?

Want video on Intermittent Exotropia

❤❤❤

Dear Doctor , well explained... simply confusing but re watching it will be ok. Are you Orthoptist Doctor? Where do you practice ???

How fixation works ? means how eye come to centre by its own ?

Tysm🫶
