Is a silent thief of vision. You may remain asymptomatic until the late stages of glaucoma, as most of us are not completely aware of our peripheral vision. In this disease the nerve fibers in charge of taking the information from the images falling on your peripheral retina are affected first. Slowly, these nerve fibers begin to die.
It has been recorded that you will not notice any changes until 40-50% of these fibers are already gone. As such, it is important to see your optometrist on a regular basis, so any changes in your ocular health status can be detected early.
Tests for glaucoma include the well-known “puff” test, where a puff of air is sent toward the eye. This measures the pressure inside the eye. When pressures are higher than normal, or have changed from your previous exams, this may signify advancing glaucoma. The photograph and OCT also provide record of how the optic nerve is changing over time. Lastly, your optometrist may have you complete a visual field test to map out the expanse of your visual area.
If glaucoma is suspected, a referral to your ophthalmologist will be made. The ophthalmologist will start you on prescribed drops. After which, you will be under the shared care of both the ophthalmologist and the optometrist. Slowing down the progress of glaucoma is essential in maintaining your vision for as long as possible, so be sure to see your optometrist on a regular basis!
