I had a heat stroke 35 yeara ago,by the time i got to the hospital by amulance. My temp had been lowered to 101 degrees, by cooling my head and body with water. i believe my temp. was considerably higher when I passed out on the street. I had convulsions and drawing of my limbs ,hyperventalating,delusional.i stayed over night in hos. I have not recovered my 20-20 vison.I saw fire before my eyes for days after,I have had poor vison eversince.Sensitive to hot weather. Has my brain been damaged ,or nerves to the eyes, or is it the eyes?.Can this cause glocoma? thanks jimmy
