I have good treatments and I am going to be fine," Bono explained on the BBC's Graham Norton show back in 2014. "Most diseases that cause blindness, like glaucoma and diabetes, can be treated or slowed down if they're diagnosed and managed properly," says ophthalmologist Michael Millstein, MD.

Glaucoma is a group of eye disorders that lead to damage to the optic nerve, and the leading cause of irreversible blindness. "Given that patients are almost certain to feel some fear, one of the most important things you can do is reassure the patient during the first few visits, especially when the disease is first diagnosed," says Ralph M. Sanchez, MD, MPH. "Make sure the patient understands that glaucoma is very treatable, something that can be controlled, and that very few patients go blind from it."

"The treatment of glaucoma is aimed at reducing intraocular pressure," says David C. Ardaya, O.D., M.H.A. "The most common treatment of glaucoma is usually prescription eye drops that must be taken regularly. In some cases, systemic medications, laser treatment or other surgery may be required. While there is not yet a cure for glaucoma, early diagnosis and continuing treatment can preserve eyesight."

The best way to avoid serious eye conditions is to get regular eye exams. "Only regular comprehensive eye exams can protect your vision from glaucoma," says Dr. Ardaya. "By enabling optometrists to diagnose the disease at an early stage, comprehensive eye exams play a critical role in successful outcomes for patients. Anyone can visit the American Optometry Association's website to find a local doctor or their state optometric association."
