Howdy all:

About a week ago my girlfriend looked at me and said, "Whoa!  What's
up with your eye?!?"  I quickly looked in a mirror to see what she
was talking about and noticed that my left pupil would not respond
to light stimulus.  Two days later I went to a walk-in clinic,
because I'd seen so many potentially scary causes linked
to "anisocoria" on the internet.  After a brief examination and a
few tests she called an ophthalmologist colleague of hers who said
it sounded like Adie's Tonic Pupil.  I'm supposed to follow up with
him soon.

Since then, I've done quite a bit of research, which has all seemed
to suggest that Adie's Sydrome is likely the cause of my tonic
pupil.  I have been all over the web researching the condition and
eventually I came across this website.  Reading through the posts
has given me a bunch of questions.  First, my pupil is about mid-
sized (not hugely dilated or constricted).  I have noticed some
sensitivity to sun-light, but nothing that sun glasses (which I
generally wear on bright days anyway) hasn't alleviated.  I have not
had headaches, blurry vision, trouble driving at night, etc. 
Basically, the only symptom I have is a pupil that does not respond
to changing ambient light (accomodation seems fine in close up
mirror testing).  Oh, and also, my knee reflex seems fine.  So my
primary concern is whether any of your experiences have involved a
progressive path to some of the other symptoms.  If all stays as it
is, my problem pupil will be little more than an annoyance on days I
forget to bring shades with me.  I guess in that scenario I would
consider myself lucky.  However, in reading some of the things that
many of you deal with daily, I must admit to quite a bit of
apprehension regarding the possibility that I may be headed for the
same kinds of problems.  Most websites I've seen have claimed that
the condition is "not progressive," but I want to hear what some of
you think about this claim.  Can anyone shed some light (pardon the
pun)?
