Eye Conditions & Treatments

Many conditions of the eye don’t have obvious symptoms, that’s why it’s important to schedule regular exams with your eye doctor. Whether you have cataracts, diabetic retinopathy, glaucoma, or wondering why your vision is blurry, Banner Health can help.


With age, the lens in your eye can become clouded by what is called a cataract. Cataracts can impair your vision and cause you to experience glare in strong light. Early-stage cataracts can be treated by fairly simple modifications such as corrective lenses, adjusting lighting, or using a magnifying glass.

Diabetic Retinopathy

Diabetic retinopathy is the leading cause of blindness in adults. It occurs when diabetes harms blood vessels inside the eye. When the vessels become weak, they leak fluid into an area of the eye called the retina. Weak new vessels can break and bleed into the retina. Weak old vessels can leak and cause swelling causing blurry, distorted vision. But there may be no symptoms, which is why it’s important if you have diabetes to get regular eye exams.

Glaucoma is an eye disease that can cause blindness. If caught early, it can usually be controlled. But it often has no symptoms, so regular eye exams are needed to catch it early. Glaucoma usually begins when pressure builds up in the eye and damages the optic nerve. The optic nerve is important because it sends messages to the brain so that you can see.
