Medical Forum / General / Vision / October 2006Pupils different sizes
This morning I woke up with swollen left eyelids. Possibly an allergy thing (I've been at my daughter's house since Saturday with one dog and two cats who like to sleep in the bed I'm using). I took a couple of sudafed-clones and the swelling seems to be subsiding, but I noticed that my left pupil is now a bit larger than my right pupil. They both shrink to the same size in bright light, but the left one returns to the larger size in ordinary room light. I'm sure I would have noticed this before, when I put my contacts on yesterday, for example. No, I'm not wearing them now. What's up?

I'm not sure whether you figured it out or not, but the vast majority of sudden-onset anisocoria (diff sizes) is medicinal. Naphazoline would dilate if you had a little bit of epithelial compromise, such as you'd get by rubbing one eye or sleeping with one eye slightly open. If they're equal in bright light, that's a good sign. Usually, a "tonic" pupil won't dilate at all. -MT > Second addendum: I bought some Target "eye allergy relief drops" because > my only allergy symptom is itchy eyes and I wanted to prevent it if [quoted text clipped - 4 lines] > > I hate having causeless symptoms :-( > I'm not sure whether you figured it out or not, but the vast majority of > sudden-onset anisocoria (diff sizes) is medicinal.

Thanks, Mike, that fits and sounds reasonable. I sleep sort of on my side with my face down on my upraised bottom arm, which means I could have been rubbing it on my shirt or something. The swelling has gone down. I'll skip the drops tomorrow and see what happens. I think my daughter's house is jinxed. The first time I kid-sat for her I strained my back on the last day picking up a cap. The second time I started coughing a week later and whatever it was lasted for two months. Now this. I blame the animals, although they're too sweet to ignore. > If they're equal in bright light, that's a good sign. > > Usually, a "tonic" pupil won't dilate at all. >> Second addendum: I bought some Target "eye allergy relief drops" because >> my only allergy symptom is itchy eyes and I wanted to prevent it if >> possible.

All back to normal this morning. I guess prayer and fasting (you DID pray and fast for me, right?) wiped out that tumor slick as sh.t through a goose!

Yay!!!!!!!!! normal pupils!!!!!! :) Actually, most allergy drops will dilate somewhat anyway, even if the epithelium is not compromised, I think. I see it a lot when we put in in pre-op eyes to shrink the blood vessels, and does not involve rubbing the eyes, or otherwise disturbing the epithelium. We also get a lot of calls from frightened patients who use allergy drops, and it is consistent with them using it, and then noticing the dilation. Since the drops work on the dilation muscle, it shows up more in dim light, when the constrictors are not working, and if more got in 1 eye than the other, it makes them unequal. The asymmetry is less in bright light since the constrictor muscle tightens down both pupils, overcoming the mild dilation effect of the drops.

Bev, I don't know anything about this but the "official name", which is anisocoria. If nothing else, it might aid you in your google search SignatureScott Reverse name to reply >> This morning I woke up with swollen left eyelids.

If nothing else, it might aid you in your google search Yeah, that turned up on almost every page, along with a list of possible causes -- none of which actually seem applicable. If I was home right now I'd call up my doc and ask, and possibly go into the office. Unfortunately I'm far away and in charge of two children, two cats and a dog and figure that next Monday is good enough if it's still bigger. SignatureCheers, Bev =================================== New sig on order, watch this space. The fact that your pupils constrict equally but don't dilate equally is a good piece of the puzzle. A pupil that doesn't open up as well is a "tonic" pupil, used in the same context as loss of muscle tone. When a young healthy adult gets a tonic pupil with no headaches or blurred vision, it is often no more than a pinched nerve in the neck. Perhaps it was that funny bed more than the cats. Put warm compresses on your neck and do some shoulder rotations to free up the nerve. If it persists, or gets worse, an exam is warranted. > >> This morning I woke up with swollen left eyelids.
