tadpole pupil

[koolotto]

I have recently been diagnosed with this condition. My right eye's pupil will change shape whenever it wants. Part of the Iris Has a muscle spasm of some kind and the pupil changes  to sort of a teardrop shape. It returns to a normal shape after around 30 seconds. It does not hurt but it does feel sort of strange,  I have seen an optamoligist and although he doesn't know much about "Tadpole Pupil"  That is what he has told me it is. My pupils are now also two different sizes. The doctor says they will probably stay that way, but he wants to see me again in two months.
   What I would like to know is what causes this? How might I have contracted this? I am 40 years old and I wear glasses, but my eyes have always been healthy and I don't have any health issues. (no high bp,diabeties, or anything)  Thanks for any input you might have.

Yes there are definitions on the web about tadpole pupil. I don't think a pupil shaped like this denotes a particuliar diagnosis. My advise still stands.

I found this definition on line, If there is a "legitamate medical term" for it I don't know what it is......

tadpole-shaped pupil

Definitions:
1. an intermittent, brief distortion and dilation of a pupil that draws one part of the iris into a peak so that the pupil resembles a tadpole; a temporary, benign condition associated with migraine that may leave the patient with Horner syndrome.

There are several conditions that affect pupil size. I am not familiar with "tadpole pupil" and don't think its a legitimate medical term.

I suggest you see a neurol-ophthalmologist. You can go to www.aao.org and use the Find An Eye MD feature to locate one in a city near you.

One of the more common conditions is Adie's Pupil.
