Pupils not equal??

Post by Karen_P »

Last night Blaze was taking a nap when one of the neighborhood kids came over and woke him up. She noticed that one of Blaze's pupils was quite large like he was in the pitch dark, the other was tiny. He looked absolutely bizarre for about 30 minutes until they both evened out somewhere in the middle, but I was in a panic. All I could think of is a head injury or poisoning. He acted fine and has been fine every since.

Any idea what could have caused this? Should I be alarmed? I've never noticed anything like this with Courage or Zach before.

I would say not to be alarmed , but if you are "never" not call your vet .Always safe than sorry. Medical knowledge is my backround . I worked at a hospital for 8 yrs on humans and for a medical director that was a neurologist . That being said ,I would worry if he didn't return to normal as quick or quicker . As the body develops so does the brain . I attribute this to his young age and an immature brain development . I remember working in ICU with infants and their breathing, especially when ill would scare a person to death to watch . These type of anomilies are attributed to brain development . Thats my take . Hope it helps .Keep us posted . I'm curious to what others say . :) Dave

Sluggish pupillary reflex *could be* due to continuing development and growth, that makes some sense, though you would expect equal reaction in each eye. And as long as the eye did finally achieve equal dialation with the other eye I think you can eliminate trauma. However, I think I would sure keep an eye (no pun intended) on this and do some testing. Take him from a dark room (where he has been for at least five minutes) into sudden light and watch the pupils for retraction, and then vice versa, using a flashlight check the eyes after five minutes of darkness to see if they are equally dialated.

In any event, if there is a definite constantcy and uniformity to this irregularity I'd sure hasten to the vet. At the very least it is not normal, but there may be a simple explanation too. Just my take on it....I find the eye one of the true mystery miracles of the body :!:

Have to agree with Dave & Barb IF..... you know there is know chance he may have experienced head trauma.... if you are sure he couldn't have snuck off & been hit by a car or had something heavy hit him in the head... then it is, in all likelyhood, just growing....

I think I figured it out....I think it was pharmacological. Blaze came running inside with a big branch yesterday. I caught him chewing it and took it away. He threw up a couple hours later, but he's taken to playing with and then eating the downed leaves, so I didn't think much of it.

I think the branch he brought in was a dead branch from an azalea. If I remember correctly, they are toxic to dogs. I have one in the backyard, and none of the dogs have ever bothered with it, so I didn't really worry about it (until now). Looks like I'll be removing a shrub this weekend.

Well, I've never liked that shrub anyway. It's too big for where it is, it half blocks the side walk, it's too close to the foundation of the house and it always looks half dead to me. I kept hoping the dogs peeing on it all the time would do it in, but I guess it's too well established to just cooperate and die on me. It's in a planting bed about 10 feet long by 3 feet wide right up against the house, and the dogs love to dig in that bed. I filled it with stone last year, which seemed to do the trick with Courage and Zach, but the stone doesn't seem to bother Blaze in the least.

So now I need to decide whether I fill it in with cement or allow Blaze to dig to his heart's content in it....make that his spot. Only problem is the dirt flies all over the sidewalk and then I wind up with a sidewalk with 2 inches of mud on it.

Oh well, I'll take the winter to think it over.

Okay, I am not a dog but.... my pupils are not the same size and never have been. When I was younger my parents sent me to a specialist and there was nothing to be alarmed about. I will admit I get the dizzy blonde thing every now and then, but I am sure it's because I am blonde not the pupil thing.. LOL!!!
