The macula is found at the rear of the eye. It is at the central part of the retina, but it is less than a quarter of an inch across. The macula has a high concentration of photoreceptor cells that sense light. That light is then transmitted to the brain and the brain perceives the light as images. Your central vision, color vision, and the details of what you see when you read, look at a person's face, see images on a screen or the brush strokes on a painting all depend on the macula. Degeneration of the macula can occur over time and result in vision loss. Our optometrists at Today's Vision Barker Cypress diagnose and treat patients that have macular degeneration.
What is Macular Degeneration?
Macular degeneration is usually age-related. According to the United States Center for Disease Control and Prevention, age-related macular degeneration (AMD) causes impaired detailed and central vision. When your central vision is impaired, objects appear blurry or milky and are not seen clearly.
Types of Macular Degeneration
There are two types of age-related macular degeneration.
- Wet AMD: The onset of this condition occurs when abnormal blood vessels begin to grow behind the retina and under the macula. The growth of these vessels eventually causes the loss of blood and body fluids to certain parts of the eye. The leaking of blood and body fluids coupled with scarring of the damaged blood vessels results in what patients describe as seemingly overnight vision loss.
- Dry AMD: The macula can also be affected by the aging process without any bleeding or leakage. It can slowly become thinner by aging and result in gradually blurred central vision. As the central vision declines, vision is eventually lost. Up to 90% of all AMD cases involve dry AMD.
Our doctor of optometry will diagnose the degeneration using a thorough eye examination. The patient's eyes are dilated, and the back of his or her retina will be magnified and examined using specialized instruments. Pigmentation changes and yellowish deposits that form under the retina can indicate macular degeneration. Other high-tech diagnostic tests might be performed for purposes of diagnosing the condition for a higher degree of certainty.
AMD cannot be cured or reversed. Much depends on how far the degeneration has progressed. Our doctor may be able to slow down the degenerative process or even improve a patient's vision. The available treatment options vary with the type of AMD affecting the patient.
