Make sure you are seeing an ophthalmologist. Also, a nerve scan is indicated. The changes on the nerve scan occur before visual field changes.

You are no doubt at higher risk because of the genetic factors, but the important thing is you are being diligent about monitoring the situation. Many people, including myself, are at higher risk, but that does not mean you will actually develop glaucoma.
In the event you do develop glaucoma, there are treatments for it that will keep it under control. Most people who have glaucoma today do not develop blindness.
