Not sure if this is the proper place to ask this or not, but, I had a severe head injury a year and a half ago and I went temporarily blind for about…somewhere between 10 minutes and an hour? I don’t really remember much.
My vision turned to a grey out in both eyes, and then I started seeing purple fractals once the grey out happened. I lost consciousness, woke up, and was hallucinating yellow, geometric grid lines, purple hazey tints, and could not see anything in fine detail.
For a long time, looking out my right eye, all I saw was a purple and black circle in half my field of vision.
I’ve had an ophthalmologist look at my eyes and told me there’s nothing wrong with my eyes themselves so it’s a brain thing. So I’ve been to multiple neurologists and they can’t find any damage - I had a CT & MRI done of the brain.
To this day I still have the hallucinations. They vary in intensity - some days it’s full on fractals on every surface and some days it’s just colors and waves and lines that shouldn’t be there. My visual acuity is better when I’m not hallucinating.
It oddly is also worse if I’m laying on my back…essentially if the back or my head/base of my skull has any pressure on it, at all, the hallucinations increase in intensity. It’s very strange. Also worse when I first wake up and start using my eyes in the morning. Like they’re still sleeping or something lol takes a minute for my vision to clear up a tiny bit.
I also see trails/images fade slowly after I move my eyes, & I see flashes of light of all colors with eyes open and closed that temporarily blind me (when eyes are open) for a few seconds. It gives me headaches and makes me nauseous.
I finally found a neuro optometrist in my area to check it out but no one has had an explanation for it at all & I just learned about CBS & wondered if anyone here had any more info, or if this sounded like that.
Edit to add - I’m not particularly disturbed by the hallucinations themselves - more so that I have no idea what causes them, what makes them flare up, & if they’ll ever go away. I just want answers lol.
