Comprehensive eye exam: what should I expect?

I really need to schedule an appointment with an ophthalmologist soon—my pupils have been looking different sizes lately, along with a few other symptoms, so I should probably get my vision checked out while I'm at it. I was reading up on it, and apparently, having unequal pupil sizes can be something you're just born with—anisocoria, I think it's called—but it could also be a sign of something more serious, like a tumor or whatever.
Honestly, I tend to get pretty anxious about doctor visits, so I was wondering if anyone could walk me through what a full exam actually entails? It would really help me prepare myself mentally. 😢
Also, does anyone know of a good medical center or a large hospital system where I could just get everything handled in one go?
Thanks so much!

I actually had pretty solid experiences getting my eyes checked over at the Eye Care Center in Chicago and grabbing some reading glasses from that little shop on Michigan Avenue—some old gentleman runs the place, very old-school style.
He does the pupil dilation tests properly, though I couldn't say for certain; you should probably check out that other thread regarding laser eye surgery discussions.

Just so you know—he’s not going to poke your eyes out... so there's no need to be terrified 😉 ...I've been seeing an ophthalmologist for twelve years now for my astigmatism and myopia, so it's really nothing to worry about

There is a Gethaldus clinic and optical shop right in the town square—just past the Panera Bread... It's quite good, and you can use your insurance referral so there is no out-of-pocket cost. You might wait about a week for an appointment, but the specialist ophthalmologist is lovely.

The exam itself is slightly uncomfortable—though certainly not painful🙂🙂

I scheduled an appointment at Mayo Clinic for ten days from now 👍

Man, those doctors! I try to follow up with them whenever it crosses my mind—but honestly, eye exams are easily the least painful checkups I’ve ever had.
To make matters worse, the nurse didn't even seem to realize what kind of exam I actually needed... I don't think she'd even heard of pupil inequality before. 🙂

Has anyone here ever heard of anisocoria?
