This past fall, Bono announced[1] that he doesn’t just wear his signature tinted glasses for stylistic reasons, in fact he is suffering from glaucoma – an eye disease that causes progressive damage to the optic nerve, which can lead to gradual vision loss and potential blindness if not detected and treated early. He was diagnosed with it over 20 years ago.
More recently, Roseanne Barr revealed that she also was diagnosed with both glaucoma and macular degeneration, which over time will seriously impact her vision.[2]
Due to regular eye exams, both Barr and Bono were able to catch their glaucoma at an early stage, begin treatment and reduce their risk for total vision loss.
Below we answer some common questions you may have about glaucoma:
Who is at risk for developing glaucoma?
Anyone! Although many cases occur in patients over the age of 40, you may also be at risk if it runs on your family, you’re diabetic, have high blood pressure, cardiovascular disease, or a history of eye injuries.
How will I notice if I have glaucoma?
Usually peripheral vision is affected first, due to optic nerve damage, which is followed by central vision loss during the later stages of the disease. Though, most types of glaucoma have no symptoms in the early stages and can only be detected through an eye exam.
How is glaucoma detected and treated?
A comprehensive eye exam is often the only way to detect glaucoma. A procedure called tonometry will be done by your Doctor of Optometry during your routine eye exam. This procedure measures the internal pressure of your eye – they will also look into your eye to observe the health of the optic nerve and measure your field of vision.
If diagnosed, daily eye drops and/or laser surgery is usually effective at maintaining your vision, but any vision already lost due to glaucoma cannot be restored. Which is why is it essential to receive regular eye examinations with your Doctor of Optometry, in order to screen and prevent you from possible lifelong damage.
