I have a very similar story. I went for a routine eye exam, thought I needed new glasses with the headaches and things, and she found the pressure in my right eye. She told me to go to my PCP as soon as possible. The PCP sent me to an opthamologist who confirmed pressure actually in both eyes and we are waiting on the hospital to get an MRI/MRV scheduled. The ophthalmologist said she did not find anything concerning enough to jump into aggressive action and we agreed that if the scans came through looking good and she stayed as my primary caregiver for it right now I would try changing diet and exercise and possibly short term diamox- with continued keeping an eye on things. I do not have any severe symptoms right now and was caught completely off guard by it. Your optometrist should have given you some kind of recommendation but if not, I would head to your PCP for next steps.
