Hello Doctor, i remember as a kid slipping down my home stairs and hitting my head right behind my right ear, y lost my vision on the center of the field and only on my right eye, i remember only being able to see at the periphery and wanting to adjust for the lack of central field vision with the peripherial vision so my eyes would flick side to side in a vibratory out of control manner i think it's called nistagmus, My Question is What could have caused this? Thanks in advance!!
these videos are so good however, it's mentioned in most books that incongrous hemianopia in optic tract lesion and congrous in optic radiation and visual cortex. So, can someone please explain this
@Cody Smith Thank you but isn't the visual cortex larger in size. Thus, lesions there could affect only a part not the whole visual field area unlike the optic tract 🤔
Hi Please respond I have a problem which is seeing a shadow or a curtain in the peripheral vision from the side of the nose and the edges of this shadow dance I went to many ophthalmologists, who emphasized the safety of the eyes, even though I worked with a retinal laser for years, thank God there is nothing wrong The question is what is this shadow and does it develop? !!
These videos are absolute gold!
So:
Optic tract >band optic atrophy..RAPD.
Optic radiation>>incongruous..pie in the sky for temporal ..
Occipital lobe >>macular sparing... temporal crescent sparing..congruous
Fantastic, a new video! Thank you, Dr. Lee and team!
Thank you so much! I start to love neuro-ophthalmology watching these videos.
Excellent
Same side half no see... Broke it down so nice
Very good videos. Many thanks for sharing. The explanation again is so clear. Please post more videos.
Thank you so much Dr. Lee, I have my final neuro practical for OT school next week and this is a life saver thank you
Fantastic❤
I really enjoy your neuro ophth lectures.
Awesome treatment of subject, Dr Lee.. fantastic!

That is very helpful ! Thank you doctor
Is everything the same if it’s left homonymous hemianopsia?
Great explanation Dr!
Wow! so thankful I have bumped into this vid!! very detailed!
Superb sir👍
wow!, amazing explanation,i almost had a mini stroke understanding all this from reading and answering questions, thanks a lot doctor
Why incongrous homonymous hemianopia occurs in optic tract lesion and why bow tie pallor occurs in the opposite eye of lesion?
Very useful....which VF do you prefer to request in your practice?
Awesome perfect thank you
I am just curious. So how would you know if you had this condition? you would just see black on one half? so like one eye was not working?
How about if a PCA infarct invovling the tract, radiation and full occipital lobe. What will be the presentation?
What about Inferior bitemporal homonymous hemianopia for craniopharyngiomas? I don't get this at all.
How can we correct Hemanopia with Prism
