am 45 years old, last year i went to see an eye doctor. He asked me to do visual field test and OCT, both results were normal but he siad i have deep cup (0.7 - 0.5) and gave me Nyolol 0.5 twice a day. My eye pressure was normal before i use this medication and till now. Recently i saw a glaucoma specialist, he said my optic nerve is fine and the same to my eye pressure, but he recomend me to keep using medication. My question is that do i have glaucoma or not.
