Resources for Eye Care

Cataracts and Cataract Surgery

A cataract is a clouding or opaque area over the lens of the eye—an area that's normally transparent. As less light reaches the retina, it becomes increasingly harder to see and vision may become dull and blurry.

Diabetic Retinopathy

Diabetic retinopathy is the most common eye disease in people with diabetes and a leading cause of blindness in the United States. If you have diabetes, you can reduce your risk for this disorder by keeping your blood sugar levels under tight control.

Eye Disorders

Detailed information on the most common eye disorders, including age-related macular degeneration, cataracts, diabetic retinopathy, glaucoma, refractive errors, and retinitis pigmentosa

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.

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.

Eye Examinations

During an eye exam, an eye doctor reviews your medical history and completes a series of tests to determine the health of your eyes.

Eyeglasses and Contact Lenses

Eyeglasses are the most common form of eyewear used to correct or improve many types of vision problems. Contact lenses are worn directly on the cornea of the eye.

Glaucoma

Glaucoma is a condition in which the normal fluid pressure inside the eyes slowly rises because the fluid aqueous humor is not able to drain properly. This pressure damages the optic nerve.

Anatomy of the Eye

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

Low-Vision Devices

Low-vision devices are categorized as either optical or nonoptical. Optical devices are magnifying lenses or closed circuit TV. Nonoptical devices are large-print books and talking computers.

Age-Related Macular Degeneration (AMD)

Age-related macular degeneration is a disease that affects an individual's central vision, making it difficult of read, drive, or perform other daily activities.

Retinitis Pigmentosa

Corrective Eye Surgery for Refractive Errors

Detailed information on the most common types of corrective eye surgery for refractive errors, including lasik surgery, photorefractive keratectomy surgery, radial keratotomy surgery, astigmatic keratotomy surgery, and automated lamellar keratoplasty surg

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.

Central Retinal Artery Occlusion

When one of the vessels that carry blood to your eye’s retina gets blocked, this can cause painless but usually sudden vision loss in one eye. Doctors call this a central retinal artery occlusion.
