Anything which helps you or makes you feel more safe is a good idea. If you feel your GP could offer more insight, then yes, you should see your GP. If it helps at all, I don't think your PDOC can diagnose a neurological condition based on vision issues alone. However it was presented as a possible problem so it's best to investigate.

I passed out twice while taking Abilify.... I could hear people talking but couldn't respond and tell them I heard them or that I was ok. I fell into and broke my sliding glass door the first time. Second time I was holding my small dog when I passed out and fell hard onto my garage floor. Could have killed us both. My doctors have now put me back on Abilify despite this. What PDOCS consider acceptable side effects and what actually is acceptable to the patient can differ.

Get some testing done to ease your mind. It's okay to tell them you'd rather try a different med.

Best of luck to you.
