Macular Degeneration

By Brandon Mayo | June 24, 2008

  View Video   Macular degeneration is the leading cause of blindness in America. It results from changes to the macula, a portion of the retina that is responsible for clear, sharp vision, and is located at the back of the eye.

Diabetic Retinopathy

By Brandon Mayo | June 24, 2008

Diabetes is a disease that interferes with the body’s ability to use and store sugar and can cause many health problems. One, called diabetic retinopathy, can weaken and cause changes in the small blood vessels that nourish your eye’s retina, the delicate, light sensitive lining of the back of the eye. These blood vessels may…

Glaucoma

Glaucoma

By Brandon Mayo | June 24, 2008

Glaucoma is an eye disease in which the internal pressure in your eyes increases enough to damage the nerve fibers in your optic nerve and cause vision loss. The increase in pressure happens when the passages that normally allow fluid in your eyes to drain become clogged or blocked. The reasons that the passages become…

Retinoblastoma

images/mp3/retinoblastoma.mp3 Every parent dreads to hear the word “cancer,” but cancer has a high prevalence in the United States. Early detection of cancer can greatly reduce the severity of the illness and increase life expectancy. Optometrists diagnose, refer, and comanage cancers that involve the eye area. The most common cancer involving the eye in young…

Acanthamoeba

By Brandon Mayo | June 24, 2008

Acanthamoeba is one of the most ubiquitous organisms in the environment, but rarely causes infections. When infection does occur, however, it can be extremely serious and vision threatening. Recently, there have been multiple reports of increasing incidence of Acanthamoeba keratitis. Co-infection with a bacterial keratitis is common both in the contact lens case and on…

Eye Coordination

By Brandon Mayo | June 24, 2008

Eye coordination is the ability of both eyes to work together as a team. Each of your eyes sees a slightly different image and your brain, by a process called fusion, blends these two images into one three-dimensional picture. Good eye coordination keeps the eyes in proper alignment. Eye coordination is a skill that must…

Color Deficiency

By Brandon Mayo | June 24, 2008

images/mp3/color_def.mp3 Color vision deficiency means that your ability to distinguish some colors and shades is less than normal. It occurs when the color-sensitive cone cells in your eyes do not properly pick up or send the proper color signals to your brain. About eight percent of men and one percent of women are color deficient.…

Spots and Floaters

Spots and Floaters

By Brandon Mayo | June 24, 2008

Spots (often called floaters) are small, semi-transparent or cloudy specks or particles within the vitreous, which is the clear, jelly-like fluid that fills the inside of your eyes. They appear as specks of various shapes and sizes, threadlike strands or cobwebs. Because they are within your eyes, they move as your eyes move and seem…

Strabismus

Strabismus

By Brandon Mayo | June 24, 2008

Strabismus occurs when one or both of your eyes turns in, out, up or down, and is usually caused by poor eye muscle control. This misalignment often first appears before age 21 months but may develop as late as age 6. This is one reason why the American Optometric Association recommends a comprehensive optometric examination…

Amblyopia

By Brandon Mayo | June 24, 2008

images/mp3/amblyopia.mp3 Lazy eye, or amblyopia, is the loss or lack of development of central vision in one eye that is unrelated to any eye health problem and is not correctable with lenses. It can result from a failure to use both eyes together. Lazy eye is often associated with crossed-eyes or a large difference in…

Astigmatism

Astigmatism

By Brandon Mayo | June 24, 2008

Astigmatism is a vision condition that causes blurred vision due either to the irregular shape of the cornea, the clear front cover of the eye, or sometimes the curvature of the lens inside the eye. An irregular shaped cornea or lens prevents light from focusing properly on the retina, the light sensitive surface at the…

Presbyopia

Presbyopia

By Brandon Mayo | June 24, 2008

Presbyopia is a vision condition in which the crystalline lens of your eye loses its flexibility, which makes it difficult for you to focus on close objects. Presbyopia may seem to occur suddenly, but the actual loss of flexibility takes place over a number of years. Presbyopia usually becomes noticeable in the early to mid-40s.…

Hyperopia

Hyperopia

By Brandon Mayo | June 24, 2008

Farsightedness, or hyperopia, as it is medically termed, is a vision condition in which distant objects are usually seen clearly, but close ones do not come into proper focus. Farsightedness occurs if your eyeball is too short or the cornea has too little curvature, so light entering your eye is not focused correctly. Common signs…

Myopia

Myopia

By Brandon Mayo | June 24, 2008

Nearsightedness, or myopia, as it is medically termed, is a vision condition in which near objects are seen clearly, but distant objects do not come into proper focus. Nearsightedness occurs if your eyeball is too long or the cornea has too much curvature, so the light entering your eye is not focused correctly. Nearsightedness is…

Visual Acuity

By Brandon Mayo | June 24, 2008

20/20 vision is a term used to express normal visual acuity (the clarity or sharpness of vision) measured at a distance of 20 feet. If you have 20/20 vision, you can see clearly at 20 feet what should normally be seen at that distance. If you have 20/100 vision, it means that you must be…
