Hello! This past weekend I was out of town for a friend’s trip. Saturday morning I woke up and felt normal, but I noticed that my left eye kind of felt off. I looked and saw that my pupil was extremely dilated while my right one was completely normal. I immediately went to the ER because I knew how dangerous it could be. They gave me a head CT scan and a vision test. My vision was perfect in both eyes and my CT scan came back clean. They said whenever I get back home to follow up with my primary doctor, and try to see a neurologist.

My pupil took about two days to go back to normal, but still even now it’s still a tad bit larger when I really look at it. I’m just worried that this could be something really serious, and I don’t know what caused it. I am on stimulant medication for my ADD, I take Vyvanse in the morning and Adderall later in the afternoon. However I don’t think either of these could cause this, i’ve been on them for a while. The ER doctor did mention that it could be caused by a migraine, but I didn’t have one that day. Over the weekend to now, i’ve had a couple headaches here and there, but not super painful ones. Also, I don’t know if i’m just worried and overthinking, but I have felt kind of disassociated as well, or “out of it”.

I just want to know some of the possibilities that could have caused this. I truly have no clue how I woke up with it. The only things I can think of is it’s something to do with migraines, or maybe an actual eye problem.
