I've read that PA can cause visual disturbances, and googling more I found that it can cause optic neuropathy. I don't have the symptoms of that, but I have realized lately that I may have another vision issue, vertical heterophoria. Long story short, I thought I was developing a phobia to driving. When I'm driving at fast speeds, especially in high traffic or on a curvy road, I feel like I'm going to pass out. And lately I've found that if I'm the first in line at a traffic light, seeing the other cars pass in front of me gives me a feeling of vertigo like I'm standing on the edge of a tall cliff looking down. I googled "feel lightheaded while driving on highways" and found out about that the problem may be my eyes.
I'm trying to schedule an appointment with an ophthalmologist, but wondered if anyone here has experienced anything like this. If there's a possible PA connection, I want to bring that info to the appointment.
Here's the story of someone who experienced this condition:
