Dry Eye Syndrome Was Exacerbating my TN

When I young, about 15 years ago, an eye doctor told me I had dry eye syndrome and I would not be able to wear contacts. She prescribed me some eye drops that my insurance didn’t cover, and I’ve been using over the counter eyedrops off and on since then. (But only when really bad! I hardly ever really thought about it.)

About a month before my TN attacks started, I started getting itchy eyes and eye pain and using drops all the time, but they didn’t seem to work and I had no medical guidance.

My TN Attacks started in December 2015, and they started in my teeth, mouth and cheek. In allergy season, my nose was getting stabbed. Later on, in the summer, it was my eyes and upper cheek. The meds kept (and keep!) going up and it seems my TN wants to stab me everywhere.

But I started getting a stab every few weeks, really hard, in my left eye – my TN is on my right. Doctors wanted to say it was idiopathic, and maybe I should be diagnosed with TN type II. Sometimes I’d get a stab on the right, and my left would just sting. But they both were getting eye stabs a lot lately, and I was getting more and more scared that my TN was taking over my whole face.

(Due to the leftside pain and an ambiguous MRI, one surgeon has rejected me for MVD surgery. )

Now it looks like those small “stabs” are common when it comes to severely dry eyes.

Now I’ve gone to a neuro opthomalagist, who diagnosed me (again) with dry eye syndrome as well as TN type I. I have been told to do 4 drops a day, for 4 weeks. My eyes are slowly calming down, and every morning I have to clean my eyes with a hypoallergenic cloth because overnight all this muck comes out of them.(I have not worn any makeup for over a year now, so it’s just the regular much) I haven’t had a stab in the left eye at all this week, just some stinging in both eyes which is relieved with the drops.

It seems that the stabs in my left side, which is TN-free (believe me, I’ve pressed it all over trying to get it to give me an attack - it was just the eye hurting, nothing else, ever!) were caused by dry eye. The eye stabs on the right may have been dry eye, too. I have only had a few small ones as of late.

I definitely still have TN. Instead of feeling pain in my eye, it’s seeming to go back to my mouth and cheek.

Here’s the thing: I went untreated for dry eye for pretty much forever. Dry eye syndrome is a real disease and the pain is triggered by light & wind. When you NOTICE dry eyes, it’s going to take weeks to treat them and get them back to healthy and you’re supposed to basically continue using eye drops forever.

I had repeatedly told my neuro that I felt light sensitive, which is NOT a symptom of TN.

So there may be things exacerbating your TN that you aren’t really aware of. My neuro was not an eye doctor, and he couldn’t have guessed I had one problem on top of my TN.

If you have pain specifically in your eye area when you get attacks, it’s considered more rare than the other branches.

Please go to a neuro opthamologist and get screened for dry eye and corneal inflammation. Neuros and doctors don’t think of it unless your first TN symptoms are in your eyes. But stabs in the eyes are actually pretty common for severe dry eye syndrome cases, according to the eye dr.

In my case, I have both, and the stabs in both eyes have slowed down, but I am still having breakthrough pain below the eye on my TN side.

If you get dry eyes, try investing in some prescription sunglasses (if you need glasses, if not, regular ones will do) and artificial tears. I was a bit scared and I flinched at first but I got the eye drops in and no attacks followed them.

Just wondering- did they ever look into a cause for the dry eyes? I have dry eyes also, and other symptoms of Sjogrens Syndrome, which is an autoimmune condition where mucus secreting glands are attacked and destroyed by the immune system. Dry mouth is also very common, and also it can cause TN and other neuropathies. They can do blood tests although not everyone has positive blood tests. Have you had blood tests for sjogrens ?
I’ve tried to look into the nerve function for myself, but can’t seem to get a clear answer, but it looks like the TN nerve might have a motor function with the eyes and their moisture production- have they ever suggested this as a possible cause for your eye problem?

Hi Jules –

No, they didn’t ever look at the cause this time around.

I swear when you go in and have already been diagnosed with TN they just decide that’s that.

I see my primary care this month and may ask for a referral to a different eye doctor. It’s hard to tell if I have dry mouth naturally or if it’s the meds. I can’t remember back to before I was on meds anymore but I def. have dry mouth now.

I also didn’t even have the eye doctor test HOW DRY my eyes are, because he was trying to be kind and avoid causing TN pain. But I was thinking of going to an eye doctor who specializes in dry eye to get more answers.

Who does the testing for Sjorgens? My primary care doctor is very willing to write referrals so maybe she can help me with this

So frustrating… in the UK a primary care doctor would be able to order blood tests to look for Sjogrens antibodies and inflammation (SS-A and SS-B are the antibodies, they also usually test for the RF rheumatoid factor, ANAs and ESR for inflammation), so presumably your primary care doctor could order those for you as a start. (Although they’re not always conclusive as 30% of people are seronegative.) Otherwise maybe your doctor could refer you to a rheumatologist for assessment. They can also test your rate of saliva production and also do a lip biopsy to look for antibodies in the salivary glands.
I’m on amitriptyline, which can cause a dry mouth, but had dry mouth for a while before I started on the medication. It might be an idea to perhaps see someone more specialised in dry eye as there are some medications which could help with that like Restasis and Exovac.
Ben’s Friends have a site- http://www.sjogrenssyndromesupport.org/ - you can read up about it without having to join if you want, and the Sjogren’s Syndrome Foundation have info too.
Hope this helps and hope that you get some answers!

The trigeminal nerve is sensory, except for the mandibular branch.

The trigeminal nerve (the fifth cranial nerve, or simply CN V) is a nerve responsible for sensation in the face and motor functions such as biting and chewing. The largest of the cranial nerves, its name (“trigeminal” = tri-, or three and -geminus, or twin; thrice-twinned) derives from the fact that each trigeminal nerve (one on each side of the pons) has three major branches: the ophthalmic nerve (V1), the maxillary nerve (V2), and the mandibular nerve (V3). The ophthalmic and maxillary nerves are purely sensory, and the mandibular nerve has sensory (or “cutaneous”) and motor functions. The eye branch is purely sensory.

Hi,

You are not alone! I was also wondering if you had Sjogren’s Syndrome. I read somewhere that 17% of people with SS have Trigeminal Neuralgia. The mechanism of this association is not known. It’s not uncommon to have bilateral TN with autoimmune diseases. Do you have Raynaud’s (cold hands/feet that turn white/blue)? Do you have any other neuropathies or just the face? Your primary care doc should be able to order the lab test for this. Unfortunately, knowing that you have SS doesn’t make the TN or dry eyes go away!

I wear contacts because when I wear my glasses it drives my TN insane! So I will use eye drops all the time so I can keep wearing my contacts as long as possible.

You are not crazy. Getting a second opinion is a great idea. Hang in there

Thanks Annie!

I don’t have Raynauds but I did had neuropathy in my hands and feet – then of course, it went away with some of my medications. My neuro (ugh, he is frustrating!) took that to mean I no longer had those pains. But a day or two before a horrible attack, I will feel a “spark” in my fingers or feet. The thing is, I know that the neuropathy was there, and real, but the doctor doesn’t seem to think that has anything to do with the trigeminal neuralgia.

I also have Hashimoto’s disease (autoimmune) and I had frozen shoulder syndrome (autoimmune) after an accident. Also I have endometriosis, also autoimmune.

I’ve actually been waiting for some sort of “big” autoimmune disease to be diagnosed, considering all of my health problems appeared in the course of a few years (aside from endometriosis). I’m 39 and all these diseases are usually diagnosed in people a bit older. I am currently waiting for an endoscopy for a gallbladder issue (porcelain gallbladder) but they are not sure it’s the gallbladder causing the pain so they’re investigating further.

In other words, I’m falling apart :slight_smile: and so nothing will surprise me if I get another diagnosis. Hopefully my primary care doctor feels she is competent enough to test for things, otherwise it’s another referral out and it’s hard to know which doctors are competent or not.

No problem. Don’t know if it helps explain our pains though. V1 is purely sensory, and the worst of my pain is in my eye, but one of my triggers is reading or being on the computer or any significant length of time. Only thing I can figure is there must be some motor innervation nearby that triggers V1. Such a frustrating, mysterious disease

I have trouble following your remark. So if the optical nerve is sensory and you have TN pain on the side the eye stabs, is it TN? I have this.

There are 12 sets (R & L) of cranial nerves (CNs). The optical nerve is CN II and is separate nerve that is responsible for sight. CN III and CN IV are responsible for eye movement. CN V is the trigeminal nerve and it has three main braches V1, V2 & V3. The ophthalmic branch (V1) to the eye and the maxillary branch (V2) to the upper jaw are purely sensory, meaning they have no motor functions and only carry sensations. The mandibular branch (V3) is mainly sensory but also has a a motor component involved in functions such as biting and chewing. My neuralgia only involves branches V1 and V2 of the trigeminal nerve and causes me to feel pain in my eye (V1), the area of a missing tooth and the roof of my mouth (all V2).

Hope this helps explain my remark.

Yes, thanks!

My worst pain is primarily in my eye too…definitely the V1 distribution of the trigeminal nerve.

Hey Melissak

Read your text with interest. I have TN with pain in my left lower jaw, teeth lips and ears. I am having cataract surgery on my left eye on next Tuesday. In preparation for that I have been requested to use eye drops several times a day because I was told I have some dryness in my eyes. This is something I never noticed. But since I have used the eye drops, my TN has been considerably reduced. Is there a connection there, or is this a coincidental time of remission? I am wondering. Hmmm! Could TN be mitigated somewhat simply by using eyedrops which will moisten the eye and send messages to the TN nerve to settle down? Wouldn’t that be great? Hopefully, if there is some connection between the eye and the TN nerve, that there will not be any bad effects from the cataract surgery.

It is interesting! I have been using drops at least two times a day in my eye and I am still having reduced pain in that area! I know for one thing I am not squinting as much.

I also got some prescription sunglasses and they really DO make a big difference. One thing is they block your eye from the wind a bit, but they also of course reduce glare.

I have been having breakthrough in the cheek area this week. The wind has been crazy. But my eye pain has still been greatly reduced.

I wish we were all able to contribute to scientific research with this stuff! We all know so much together, but there are no doctors that are taking notes on us all together.

I hope your cataract surgery goes well!

Thanks for responding. Had my cataract surgery on Tuesday. It went normally as expected. My vision in that eye has improved greatly. I will have the other eye done in a little over 1 month. I still am having lessened pain. So the question still looms is am I in a period of some remission or are the eyedrops doing something good? This would certainly be a great thing cause I have been living with TN for over 20 years.

Glad your surgery went well.

I hope you find out if the eyedrops are helping! Or you have a long, long period of remission. Both of those are good in my book. :smile:

My remissions only last a few days until I get at least a breakthrough pain to remind me I still have TN.

But my breakthrough pains have only been about once a day since I started the eyedrops. They have dropped down from much, much more frequent pains. Like maybe a dozen a day. Before I started the gabapentin in February, I was still getting breakthrough pain probably 20 times a day. So I am grateful things are improving right now myself.

Rich - I had my cataract surgeries last fall. I did get an attack while they were working on my left eye (TN side)…even though my eye was completely numbed up for the surgery. They gave me some IV pain med and it helped a little. But no problems after the flare subsided. No problems with doing the other eye. I have used eye drops over the years for allergies that cause terrible eye itchiness, but have never noticed any affect on my TN eye pain. Glad that the eye drops have reduced your pain. Do you know what kind of drops they are. I had to use 2 different kinds of drops for almost a month after each cataract; one was an anti-inflammatory and the other was an antibiotic…but neither seemed to have any effect on my TN pain.

Hi Not_Again
My post surgery eye drops are Vigamox, Ilevro, and Prednisolone Acetate. I was told to use Refresh Plus drops for about 1 month prior to surgery since my eyes tended to be dry. I will have my 2nd eye done in a week or so. I have still been “good” since my last post, and as you know, any relief is great.
