Right pupil larger, espec. on waking, then back to normal. opthamo said eyes good and pupils were even, months ago, but still very noticeable at times?

Pupil: A reasonable number of people have anisicoria or irregular pupil size. However, I am not aware of this being transient. If you take meds to sleep, decongestants, or antihistamines at night time this may be causing this.

Pupil asymmetry or : Anisocoria is actually quite common and present in 20% of "normal" healthy patients according to medscape. We are taught as opthalmology residents that there are allowable amounts of anisocoria. If there are no other symptoms and you have had a complete exam, i wouldn't worry too much. If you are doubtful, get a second opinion.
