I was diagnosed with glaucoma 4 years ago, when I was 74 years old.
In early 2015 when I was 74, I became aware of a fuzzy sensation and blurry area in my field of vision, to the lower part of my eye, and whilst I was having my annual eye test for spectacles I mentioned this to my optician. He put me through some tests including a field of vision test (as well as my normal pressure test) and he suspected I had glaucoma in my right eye, although my pressures were not unusually high.
I have worn spectacles since I was 15 years of age as I was found to be myopic. I have had spectacles with changing prescriptions over the years and until 2015, I had not noticed any field of vision loss - at least none I was aware of.
During my late teens and early 20’s I participated in a sport that was very vision intensive. Small bore rifle target shooting. This necessitated extremely good eye sight and body control. Maybe it was coincidental, but during those years I spent a lot of time staring and concentrating with my right eye.
Now my eye seems to be stable with pressures of 10-12, a little high but not extreme according to my ophthalmologist. I have been on eye drops for both eyes each day since diagnosis. My ophthalmologist refers to my case as atypical as I did not have high eye pressures to begin with. Meaning, I think, regular eye pressure checks did not effectively indicate that I might have a problem.
Regardless of regular eye pressure tests showing no problem, it may be wise to have regular field tests, to provide early warning signs, especially for cases such as mine. Early treatment might be more effective in arresting the development of the disease.
