question: Hello doctor,One of my friends recently pointed out that my pupils are sometimes uneven. I searched and got many scary possibilities. However, I did look at pictures from years ago and noticed different degrees of anisocoria. Now that someone has pointed it out, I obsess over it and see it a lot. It only happens periodically (at various times during the day), no other symptoms. What could cause anisocoria that is occasional and been going on at least three years as indicated by pictures? I am on medications for gastroparesis and generalized anxiety like Zofran, Phenergan, Pantoprazole, and Paxil. I read Paxil could potentially cause anisocoria.
