What could be the reason for having visual issues and seeing a lot of shapes after shutting the eyes?

Hello doctor,

I have been having neurological issues for years, but recently they have worsened. I have been having lots of visual issues, like feeling things look dim at times, feeling things look different, feeling spaced out, etc. I was diagnosed with migraines and FND (functional neurological disorder) about 18 months ago. Since then, I have been having more visual issues. I find it hard to go from light to dark and vice versa. I have lots of long-lasting after images if I look at lights. Another disturbing symptom is that at night, if I wake and then try to go back to sleep, I see a lot of 3-D shapes and sometimes vague pictures or lights when my eyes are shut. They are not there if I open them, but I am fully awake. Last night I went to ER (emergency room) as I suddenly had a bright line in the right visual field. It was like I had been staring at a strip of light for ages and could see it every time I blinked. It lasted for about 45 minutes. I also developed a headache. They said it was likely a migraine, but I never had that kind of light sensitivity before.

The blood tests and ECG(electrocardiography) are fine. I had a brain MRI (magnetic resonance imaging) two years back, and also a brain EEG (electroencephalogram), and both are fine. I am worried about what is going on. My doctor is not concerned. I have EDS (Ehlers-Danlos syndrome), Sjogren's syndrome, and anxiety. I also suffer from depersonalization.

Please help.

Thank you.

Hello doctor,

Any ideas about the pictures that I see when I close my eyes? I also have tinnitus.

Thank you.
