    • Age-Related Macular Degeneration

      Age-related macular degeneration (AMD) is a disease that affects a person’s central vision. AMD is the most common cause of severe loss of eyesight among people ages 60 and older. Only the center of vision is affected with this disease.

    • Anatomy of the Eye

      The structures of the eye include the cornea, iris, pupil, macula, retina, and the optic nerve.

    • Cataracts

      A cataract is a clouding of the lens of the eye. This is an area that is normally clear. As this clouding happens, it keeps light rays from passing through the lens and focusing on the retina. The retina is a tissue lining that is sensitive to light. It is located in the back of the eye. This cloudiness happens when some of the protein which makes up the lens of the eye begins to change its structure. It then gets in the way of your eyesight.

    • Central Retinal Artery Occlusion

      When one of the vessels that carry blood to your eye’s retina gets blocked, it can cause you to lose your eyesight. This problem often happens suddenly and without any pain. This is called a central retinal artery occlusion (CRAO).

    • Common Eye Disorders

      One common eye disorder is conjunctivitis, sometimes called pink eye. It's an inflammation of the blood vessels in the eye membrane. Another common disorder is a chalazion—a small bump that develops on the upper or lower eyelid.

    • Diabetic Retinopathy

      Diabetic retinopathy is a leading cause of blindness in American adults. It’s caused by changes in the blood vessels of the retina, the light sensitive layer of tissue at the back of the inner eye. In some people, retinal blood vessels may swell and leak fluid. In others, abnormal new blood vessels grow on the surface of the retina. These changes may result in vision loss or blindness.

    • Eye Care Specialists

      An ophthalmologist is either a medical doctor (M.D.) or an osteopathic physician (D.O.). An optometrist is a doctor of optometry (O.D.) but is not a medical doctor. An optician is a technician who fits eyeglasses.

    • Glaucoma

      Glaucoma is a health problem where the normal fluid pressure inside the eyes slowly builds up and doesn’t drain properly. Instead, the fluid collects and causes damage to the optic nerve. The optic nerve is a bundle of nerve fibers that connects the retina with the brain. This damage leads to loss of eyesight.

    • Refractive Errors

      Astigmatism is one type of refractive error. It's a condition in which an abnormal curvature of the cornea can cause two focal points to fall in two different locations—making objects up close and at a distance appear blurry.

    • Retinitis Pigmentosa

      Retinitis pigmentosa is the name of a group of eye diseases that are passed down in families. All the diseases involve the eye’s retina. The retina is the nerve layer that lines the back of the eye that is sensitive to light. All the diseases cause a slow but sure loss or decline in eyesight.
