I am only 21 years old and I am so depressed and cannot eat anything. I started seeing a black dot in my left eye, which started on Friday two days ago. I went to my optical doctor last week, which dilated my eye and said everything is fine just have floaters in the eye. Today I went to ophthalmologist just to get another opinion and they did Fundus photo, corneal pachymetry test, and GDX test. I was told the same about the floater but be aware of flashes. The doctor also told me that I might have glaucoma in both eyes because of thick optic nerve. The doctor didn't prescribe me with any medications just told me to come next month. I am so scared will I get blind. I been told their is no cure for it. Is this because I play too much video games and stay on the computer? Please help me I cannot sleep just crying all day.
