Hello. I'm a healthy 40-y-o woman who has had an afterimage for approximately 3 weeks. It is a streak in the right lower field of my vision. When I close my eyes it is white; when I open my eyes it is gray/black, then disappears.
I've had these "afterimages" on and off for many years. I have no other symptoms, though I think that these tend to occur during allergy season (I have allergies to pollen). When I was in my teen years, I had classic migraine with aura--I no longer have those episodes.
Instead of going to an ophthalmologist to find out my eyes are fine (seems like many on this forum have gone down that road, and I go every 2 years, anyway), would you hypothesize that this is a neurologic issue? Is it dangerous, or something I shouldn't worry about?
Thank you for your advice.
