Serving the needs of Tucson, Arizona, patients, Dr. Cameron Javid and the Retina Associates team provide advanced ophthalmologic care for a variety of eye conditions. Among the conditions for which Retina Associates offers exceptionally high-quality treatment is age-related macular degeneration (AMD), which stands as the most common cause of vision loss worldwide in people over 60 years of age.
A condition centering on the gradual breakdown of the macula within the retina, macular degeneration impacts the patient’s ability to clearly make out details. The two basic types of the condition are dry, non-exudative AMD, and exudative, wet AMD. The latter form of AMD results in more severe visual impairment and accounts for the vast majority of blindness incidents associated with the disease.
Composed of a complex cellular network, the retina stands as one of the body’s most metabolically active tissues. The tissue receives its oxygen and nutrient supply through blood vessels in the retina and choroid layers that enable high blood flow. This process can be disrupted through problems with vascular endothelial growth factor (VEGF), which can lead to abnormal growth of blood vessels in the eye as well as hemorrhaging and edema beneath the macula. As these lesions turn into scars, the macula is destroyed and central vision deteriorates rapidly.
Reflecting its seriousness, cases of wet AMD require immediate treatment that includes the use of VEGF inhibitors as a way of shutting down the choroidal neovascularization process. In addition, several clinical trials are available with new treatment options for patients that qualify.
