Worried of my eyes

I am 18M (1,7m, 65kg) and I am not under any medication nor do I smoke or drink frequently.

I was in 5th grade when I got an epileptic seizure. The hospital couldn’t find a cause and said “let’s just say you hit your head since there is no other explanation”. Two years ago I went to the eye doctor because I kept seeing flashes of light in my eyes and big black dots. They diagnosed me with ‘other vitreous disease’, since they found a small hole in the back of my left eye (probably caused by the head hit that lead to the seizure).

Now two years later I still see black dots in my vision. If I look into the sun it will make a black dot into my vision for many minutes. If a flashing light is directed into my eye it will cause white and black lines in my vision that will stay for several minutes. Sometimes without any “reason” (like a bright light) these random dots and black lines will appear in my vision. Also my left pupil is often bigger than my right one (Ive seen if myself and been told by other people aswell). I’ve become super sensitive to light but i haven’t gotten headaches from it (which is weird). I feel like the only issue is in my eyes and its scaring me

My question is, should I go to the doctor again to get my eyes checked? I feel like im overreacting but for some reason my brain is thinking that I have a brain tumour or something that is causing these symptoms. Also are those symptoms normal (dots and lines). every time i tell my friends about them they look at me like im crazy.
