Temporary Anisocoria in 5 month old?


Recommended Posts

Last night I put Finn in his crate and went to pick up dinner. We were back home in 20-30 minutes. We set the food down and put some things away, then I let him out of his crate. He was patiently waiting as usual.

Finley looked up at me and made eye contact, and I almost screamed. His left pupil appeared to be GONE. With a blue eyed pup, this made him look ghostly.

 

His right eye was completely normal (at least, it looked normal) and his left pupil was constricted to a pin point.

 

I called the emergency vet, and consulted Dr. Google. Everything points to:

  • Head trauma - How? He was in his crate...
  • Scratched cornea - Possible, but again he was in his crate and there is no visible scratch. I can't imagine him scratching his own cornea to the extent that it would constrict his pupil. Still, very possible, and the most likely cause.
  • Neurological or nerve problems - :blink: He's only 5 months. I pray it's not something like this.

They have since evened back out. (took maybe 30 mins)

 

Have you ever experienced anything like this?

Hes going to the Vet today at 4:30, but I'm curious if this is at all common, or if it is an indicator for any diseases seen in BC's. You guys are way more knowledgeable than Dr. Google.

 

Here are some photos of his normal eyes ( sorry its the best I have of his eyes ATM ) and him with his eye after it started going back to normal.

After looking at the photos, I'm wondering if the right eye is actually dilated while the other is constricted. Very strange.

Comparing the two pictures, his right eye looks dilated. But very interesting overall. I hope you post back later after the vet visit. I'm assuming they will stain the eyes to check for a scratch if they think it's a corneal injury.

Looks similar to what you were talking about.

 

That looks very similar. The scary thing was that the left eye pupil was so small it looked to not be there at all. That may have distracted me from the fact that the other eye was also dilated.

 

I hope this doesn't become a reoccurring thing like the dog from the post, because it freaks me out. He looks possessed with no pupil. I really wish I would have thought to take a picture before it started to go back to normal.

 

Today is creeping on, I am ready to get my baby to the vet.

It's unlikely to be a corneal scratch if he isn't showing pain and sensitivity to light. Corneal scratches hurt like crazy, make the eye water a lot, and even cause the eye to swell shut. Good luck at the vet today. I think BCs enjoy taking 10 years off our lives.

Yep, I'm going to have a few gray hairs from this one. I am so nervous.

He is at the vet now, and I am stuck at work for 15 more minutes.

 

I've never dealt with a corneal scratch, but he hasn't been showing any signs of pain. sigh.

My Nan also had a very constricted left pupil four days ago. Both of her eyes are blue as well and yes, it sure is obvious when the pupils are different. She was also holding that eye shut, though. When I took her to the vet, he stained her cornea but couldn't see a scratch. She did have conjunctivitis.

 

The vet mentioned a dog 30 miles away that had Horner's Syndrome and also presented with one very constricted pupil. However, with antibiotic eye drops, Nan's pupil was back to normal in one day.

I've had my panic button pushed for today, thank you! BCFinley, if it is a corneal scratch, they tend to heal very quickly. That's good, considering they hurt like the very devil.

 

Hope it's good news from the vet and he's better soon.

Well, the vet visit was anticlimactic. She suspects he suffered some sort of head trauma. Both of his eyes checked out perfectly fine. We were instructued to run a panel on him to test for some disorders to be safe. I'll have to do some more research to find out exactly what I'm testing for, because the boyfriend does not pay good attention, and I made it to the vet as they were walking out.

So, no real answers as of now. Hopefully everything comes back clear and he was just having a moment. He is EXTREMELY Clumsy, so I guess he could have fallen and hit his head.who knows. I will keep you all updated on his condition if there are any changes. Thanks for all the imput!

I'm sure the vet wouldn't mind if you called and explained that you hadn't been able to get there for the visit and would like to hear her or his thoughts directly. I think most would understand that and be willing to talk to you on the phone for a few minutes. :)

 

Best wishes.

When Tess was 5 months old she went blind. I found out she had congenital chataracts. She had surgery 10 days later has she needed to be on some meds before surgery. During that time before surgery, one day, we where at home and I looked at her, the hair all around one eye was all bloody, like her eye had exploded (I completely freaked out). She was having high pressure on her eyes and both me and the vet thought it had caused a vein to burst. But the specialist, when he saw her a few days later, said it was a cat scratch (I do have a cat). Point is, she never showed the least sign of being in pain, it didn't bother her at all. It was a hell of a time for the cat to decide she needed to be thaught manners, I was already going over the edge with the prospect of surgery and the possibility it could go wrong.

Were back at it again :( This time, they didn't go as far, and it was opposite.

Took him in for shots and his eyes were messed up. Vet didn't even notice AND gave him the wrong shot. Safe to say I will not be seeing her again.

That's what I'm saying! How can you shove a needle in a dog (containing the wrong vaccine) without looking at them (when they were just in for an emergency).

 

I was already annoyed that they had me see the woman vet, when I prefer the man.

I will continue going there, but I will NOT be seeing her. Dr. Piske is the only reason I will be returning.

I don't trust some vets. Last February my golden had a dental done and long story short she had a stroke because a tech severely messed up her anestesia. Anyways we brought her in because she was knuckling her front paw and bobbing her head. The vet said the knuckling was from the IV and she was bobbing her head because she (our dog) was telling us to go home. Well the knuckling was due to the swelling in her brain due to the stroke which we didn't know she had and the bobbing was a seizure. I will never see that vet ever again. Her colleague saved our dog's life. We will only see him from now own. Some vets just don't see the subtle signs that others do. And never let a vet tell you nothing is wrong when you know something is. That is one thing I now live by. If you have to get a second, third, fourth opinion etc.

Hi!  My 4-month-old border collie Chloe is experiencing the same exact thing...it has happened three times now, twice in her left eye, once in her right.  no other side effects, no irritation, and it goes back to normal within 30 minutes...The vet gave her a full eye exam and everything was fine, she said she must've gotten something in her eye...but now its happened two more times. Did you ever get a clear diagnosis?

Our little girl has had this happen twice (that we know of) and both times, they have returned to normal in a short time and it never seemed to bother her either time.  I assumed this was something of an injury or swelling due to her violently shaking a rubber squeaky chicken... "Knock it off, dog!  You're gonna rattle your brain loose again!"  HAHA  Anyhoo, I talked to MY ophthalmologist and she said "Eyes are eyes, for the most part, be it human or dog .  Pupil function is controlled by the brain and that it may be "brain related" (injury or underlying condition) if it isn't an outright eye injury.  There may also be a predisposition in the specific breed (Blue Merle Border Collie) leading to the problem. "  She told me that there are actual K-9 ophthalmologists to consider rather than a general veterinarian and that's the route we should take... and SHOULD take.  I will bring it up when I see my vet again but in the meantime, we just don't let her turn into a rabid jackal with her toys!
