Is high eye pressure a typical sign of glaucoma?

Hello doctor,

I have high eye pressure of 30 and 24, visual field loss, and at times I go completely blind in both eyes. I have also gone blind in just one eye. I just went back to the eye doctor when I had the pressure of 24 and 30. I have been there three times and each time I had a high eye pressure. He at first told me everything looked good until I asked him what my pressure was again because he specifically said my pressure was good when I knew that it was high. He told me that it was fairly high when I asked for it but he says I do not have any optic nerve damage and that it is highly unlikely that I have glaucoma because I am 23 years old. But my research has told me differently that high eye pressure alone does not mean that that you have glaucoma but if you have visual field loss or optic nerve damage with your high eye pressure then you do. So I do not know what is going on? Can you please help me understand and is it possible that I do have glaucoma and should go to another doctor?
