Horner's syndrome describes the constriction of the pupil of one eye, the partial drooping of one eyelid, and the loss or reduction of sweating on that side of the face. What innervates all of those things? The sympathetic nervous system!
How do sympathetic nerves get to these places? Let's find out!
Then we can consider how these nerves might be injured and lead to Horner's syndrome, clueing us into what other pathology might be causing the signs and symptoms that we see.

This has been the best knowledge I’ve learned since my diagnosis of my pancoast tumor in 2014. Tumor was removed but damage was done. My symptoms of Horners Syndrome are severe still to this day. Include all three normal symptoms of HS but I also have regular episodes of flushed face on opposite side of face accompanied by severe sweating throughout my entire body. This happens to me about thirty to sixty times a day. Including while I sleep. I’ve noticed that these episodes are also triggered by emotional stress or if I need to urinate. Or maybe I have to urinate because of the episode, not sure. Thank you for these great explanations, as it helps me understand how to best deal with my symptoms. My symptoms are almost unbearable. I’m 55 yo F,stage 4 nsclc and lobectomy in 2014. Two rounds of chemo, one round radiation and finally immunology has helped me to still be here. I also have severe pain from the damage/erosion of my T1-3. This area has been built up surgically and the trauma is severe. Are there any other ways to help deal with my symptoms, that you are aware of? Thank you so much for posting this video. It’s been very interesting and helpful.

Have you improved? Look up fascial counterstrain technique for possible help.

i severed c5 to t1 in 1991. my pupil was pretty much non reactive and the eyelid closed. the effect is mostly unnoticable now except when i am tired. cant say i noticed the sweating aspect. informative videos.

@cl2471 Жыл бұрын

The sweating part is so annoying. I literally only sweat on the opposite side of my face. Between that and the odd pupil dilation people just stare at you like this 😮 lol

I recently had a ADCF operation on C4/C5 and C5/C6. After many tests because of all of the symptoms as described in this video, the surgeon said while my spine was exposed with the help with retractors they believe it restricted blood flow because of the time the tool compressed the nerves and arteries. I have not heard of this problem before and I was first diagnosed with having a stroke, this was a very hard thing to comprehend but after many tests it was confirmed as Horner syndrome. Finding information on doctor Google it can revert back to normal but not in every case. I will have to wait and hope I return back to my pre- op state.

Hi Sam, another brilliant video. I always had a brain block with understanding the autonomic nervous system prior to watching your videos. You are a great communicator. ?? IS THERE A SMALL PROBLEM AT 4.09 WHERE YOU UNINTENTIONALLY INFER THAT THE SYMPATHETIC SYSTEMIC CAUSES VASODILATION OF THE SKIN? Just FYI. Love and respect.

@SamWebster 3 жыл бұрын

Thanks. I was trying to explain that sympathetic innervation regulates blood flow to the skin without getting into the details of how. The important idea in this case is that post-ganglionic sympathetic neurones travel throughout the body.

I just had a patient who developed Horner's Syndrome few hours after placement of labor epidural. I would imagine the local anesthetic used for epidural might block the Stellate Ganglion.

I'm 36-years-old and was recently diagnosed with Horner's Syndrome. I started noticing the symptoms about 3 months ago, but I can see some mild ptosis in photos up to a year ago (but it's hard to tell for sure in the photos). My doctor ran a chest CT w/ contrast, a neck CT w/ contrast, a brain MRI, and an MRA of my head & neck. All scans came back "normal" with no evidence of tumors, stroke, or lesions. That was a sigh of relief, but I still have worry in the back of my mind that they could've missed something. At this point, the doctors don't really know what could've caused it, but I did have a barbell slide back onto the front of my neck/collarbone area a few months ago while doing front squats (with the barbell resting on the front of my shoulders, right in front of my collarbone). It did hurt my collarbone and crush my trachea a little bit, but it only hurt for like 2 minutes and I've never had any pain or issues after (and I finished my workout that day).

What I'm trying to visualize is the exact route of the nerves that are affected in Horner's Syndrome. For example, I've read that the nerves affected exit the spine near the C8, T1, and T2. However, I want to visualize what kind of route they take when exiting the C8/T1 until they meet back up with the sympathetic chain. I just don't understand what could've caused this to happen since the doctors can't find a cause and I'm trying to figure out the exact route these nerves take from the time they exit the spine until they meet with the sympathetic chain in the neck. I have some pain (daily) in the lower-left side of my neck, near the supraclavicular brachial plexus area, but it's only mild pain. I was worried about a Pancoast tumor or something like that, but they checked my lung apices in the Chest CT and the Neck CT and don't see any evidence for a tumor. So, I'm basically at a loss right now.

What drugs are you taking for horners syndrome ? Only eye drops or oral medications also ? Pl.reply

@omanita7289 Жыл бұрын

Diagnosis Horner syndrome in 2019. Now I now it's related to sarcoidose that's the game changer. Because there is not so much information about the decease it can cause many different problems. In my case my immune system attack itself. It's a scary diagnosis for me 1 of more and can be inherited

if the injury of brachial plexus is near the spinal cord it leads to hornor syndrome and if away it leads to klumpke palsy ? Am i right!?

@SamWebster 3 жыл бұрын

Klumpke's palsy describes the signs and symptoms of an injury to the lower trunk of the brachial plexus which is formed from C8 and T1 spinal nerve roots, right? And sympathetic neurones come out of the spinal cord from the T1 level down to about L2 and L3 levels. So if the lower part of the brachial plexus is injured close to the spinal cord it's more likely that the sympathetic nerves at that T1 level may also be damaged, giving Horner's syndrome in addition to Klumpke's palsy. Complicated!
