Retina Associates provides specialized care for retinal abnormalities to patients in Tucson, Arizona. Through Retina Associates, Dr. Cameron Javid and his fellow physicians treat numerous individuals with macular degeneration.

Age-related macular degeneration, or AMD, is the most common cause of vision loss in the United States today. It stems from the deterioration of an area known as the macula, which lies in the center of the retina at the back of the eye. In a healthy human eye, the macula is responsible for receiving and processing information from the patient’s central field of vision.

Because the retina is responsible for translating light into signals that the brain can read as vision, its degeneration can be devastating to a patient. Macular cells that no longer function can in turn no longer correctly tell the brain what the individual is seeing. This manifests as blurriness, image distortion, or even darkening in the affected visual field.

In most cases, this process occurs because the macula begins to gradually thin with age. At first, this does not cause noticeable symptoms but instead prompts the development of small deposits under the retina, which an ophthalmologist may notice on examination. Vision loss then slowly begins and worsens as damage increases.

Dry macular degeneration may progress into the disease’s wet form, which occurs as a result of abnormal blood vessel growth under the retina. These vessels are structurally unsound and leak into the retina, which in turn can cause rapid and severe vision loss. Wet macular degeneration requires timely medical treatment, so that a retina specialist can treat the condition with injections of medicine into the eye or cold laser.

Dr. Cameron Javid, and the other retina specialists at Retina Associates in Tucson, Arizona offers eye care involving the retina and vitreous. In other words, conditions that involve the back of the eye. Retina Associates also provides expert treatment for macular degeneration, which involves reduced visibility in the a person central vision.

The condition is caused by an age related cell loss in the macula, which lies in the back of the eye within the central retina. The macula has vital functions, such as helping visualize small details, and is necessary in performing functions such as driving and reading. While it does not impair peripheral vision, macular degeneration causes blurriness, distortion, and darkness, and affects the ability to focus on near and far objects. As the condition progresses, tasks requiring focus, such as threading a needle, may become extremely challenging.

Age-related macular degeneration (AMD) is the most common form of the disease, and 90 percent of patients have dry AMD. Comparatively wet AMD involves sudden, mild to severe loss of central sight, as abnormal blood vessels expand in the back of the eye.
Fortunately there are several treatments available to treat wet AMD and many current clinical research trials available at Retina Associates in Tucson, AZ
