LESIONS OF VISUAL PATHWAY || SCOTOMAS EXPLAINED|| Junctional scotoma|| HOMONYMOUS HEMIANOPIA

Welcome to insight ophthalmology!
The video discusses in detail about the visual field defects arising due to lesions of the visual pathway. The difference between congruous and incongruous field defects is explained. and also the difference between HOMONYMOUS and heteronymous defects
the video explains sequentially the defects arising due to optic nerve lesions, optic tract lesions, lesions of the lateral geniculate body , optic radiation and visual cortex.
The video also explains the fancy terms like JUNCTIONAL SCOTOMA, " PIE IN THE SKY ", and " PIE ON THE FLOOR".
The video explains in detail the macular sparing defects and macula involving field defect seen in visual cortex lesions.
"INSIGHT OPHTHALMOLOGY" is run and managed by Dr Amrit Sahil Panjwani ( MBBS, MS ophthalmology). WE hope the video is useful to you.

Longer videos can be a little tiring. But sometimes the quality of the video and concepts cannot be compromised for the length of the video. 😊
For easier navigation through the video and specific subtopics, kindly refer to the time stamps present in the description part of the video. And in the comments!
Thank you!

You are the best..❤

[@user-wp2qq5mp6i]

Thank you so much Dr Amrit...All your videos have been very helpful and this was exceptional 👏

[@dr.md.mamun-or-rashid3211]

This video is very much helpful for clearing concept about visual pathway,we want more and more videos on ophthalmology.. 😍🥰

[@dr.md.mamun-or-rashid3211]

Excellent video.May God bless you.❤️❤️❤️

[@tulikapandey7842]

Ma'am please 8f possible make video on those advanced lesions of LGB.
THANK YOU

[@ishneetkaur4180]

Ma'am kindly make a video on ciliary ganglion too!!

[@sukhdevsingh-in5ee]

extremely awesome- u always the best hats 👑⛑👒🎩of u Dr Amrit👍👍👍

Comprehensive video ma'am 💕

[@zafarullah3866]

Mam I am from Pakistan, you are so nicely explaining and clearing concepts , but
There is one request that kindly don't delete some parts of videos, for example the part of video where you were explaining etiology of optic chiasm pathology like aneurysm, third ventricle dilatation etc , that part deleted ,

[@syedmedicose7477]

just an excellent explanation, stay blessed maam, may ALLAH PAK SHOWER HIS BLESSINGS ON U & UR FAMILY IN BOTH THE WORLDS AMEEN!!
🥰😇

[@InsightOphthalmology]

👏👏👏

[@kiranbalamallik6454]

Ma'am what would be presentation in post and pre fixed chaismal lesion ?

[@rakeshgulati3622]

Please also inform about solution to Right Homonymous Hemianopia.

[@spiritualawakening2753]

Why is no 7 superior quadrantonopia and why is no4 binasal please can u explain I have exam in a day . Thanks for the lovely video .

[@avisheksarraf2046]

Same problem mine also

[@shubhangigupta359]

Why lesions behind lateral geniculate body not associated with optic atrophy ?

[@InsightOphthalmology]

Because the second order neurons synapse here and then the third order starts. The third order neurons are from geniculate body to cortex.
Any lesion behind the LGB will effect the third order and not second order ..and therefore there won't be atrophy seen in optic nerve usually

[@shubhangigupta359]

@@InsightOphthalmology thank you mam
