DEAR DR. GOTT: I am a 65-year-old female that is relatively healthy. I take atenolol for pre-hypertension and tapazole for hyperthyroidism, along with the recommended supplements calcium, vitamin D, fish oil, and fiber. I eat healthfully and am still working actively as a teacher. I am 5’8” and 140 pounds.

The results showed the interior of my eye is normal; I have no retinal problems, no glaucoma and the nerve is healthy. I had an MRI which was normal. My dilemma is this: Do I pursue it further by going to one of the eye institutes here on the West coast or just let it be and see what happens? I would appreciate your thoughts on this.
