I was diagnosed with glaucoma about 36 years ago when I was 30, by a very perceptive optometrist when I went to get my glasses checked.
I did have a family history, both my mother and aunt had glaucoma, so I was immediately sent off to an ophthalmologist, who confirmed my condition. Fortunately, it was caught early, and I have suffered no loss of vision.
Over the years I have been on nearly every drop available, have had laser treatment, and cataracts removed. I am so grateful that the treatment available is successful, controls the pressures, and continues to improve. This does help to allay any fears I have about a potentially life changing condition.
Everyone should have regular checks for glaucoma regardless of your family history, but even more so if that is your case. If detected early, it can save your sight.
