Age-related macular degeneration (AMD) is a degenerative disease of the retina that primarily affects the macula, the center of vision, and is the leading cause of blindness in patients over 55 years of age.
May your memories not be erased with time.
Types of age-related macular degeneration
Dry (Atrophic) AMD: This type of macular degeneration is caused by the accumulation of drusen, yellowish deposits beneath the retina, which causes progressive retinal atrophy. It is usually asymptomatic and predisposes to acute bleeding and central retinal atrophy. It requires periodic monitoring, and it is recommended to take antioxidants, maintain a balanced diet, reduce light exposure (in some cases with blue light filters), and not smoke.
Wet or Bleeding AMD: The proliferation of new blood vessels that destroy central vision. The natural progression of wet AMD can cause central blindness.
Causes
Age-related macular degeneration is a genetic disease influenced primarily by four factors:
Genetics: It is a highly prevalent hereditary disease, affecting up to 22% of Caucasians and somewhat less prevalent in pigmented races. In the United States, it is estimated that 11 million of its population of 324 million suffer blindness due to Age-Related Macular Degeneration.
Tobacco: It is a powerful oxidant and has a very negative influence on the progression of the disease.
Light exposure: Greater exposure to light, both natural and artificial, is associated with a higher risk of AMD progression. It is always advisable to reduce your exposure by wearing sunglasses. In intermediate and advanced cases, the use of visible and invisible blue light filters may be recommended.
Cardiovascular disease: A diet rich in antioxidants helps protect against progression. Conversely, a diet poor in antioxidants increases the risk of disease progression.
Symptoms of macular degeneration
Blurred Vision: Decreased central vision (distance vision and reading ability are reduced)
Distorted Vision: Straight lines appear wavy.
Early diagnosis is essential for treatment to prevent vision loss. The recommended frequency of checkups will be determined by the severity of the disease (depending on the stage of macular degeneration: early, intermediate, or advanced), ranging from every 6 months to even a few days. Self-assessment is also very important. At PRESBIT, we teach our patients how to use the necessary tools to periodically monitor the quality and quantity of their vision, and if any changes occur, they can visit their nearest center.
We care for your macula with precision and medical experience.
Treatments
There are two types of treatments for Macular Degeneration:
Intravitreal antiangiogenic (anti-VEGF) therapy is the treatment of choice for wet (bleeding) age-related macular degeneration and consists of serial injections of intraocular medication aimed at inactivating new vascular lesions. Laser treatment: Alone or in combination with intravenous medication with activity on new vascularization, such as Verteporfin, it is sometimes used to improve disease control. Surgery: In rare cases, intraocular surgery may be necessary to treat massive hemorrhages or other retinal damage.
Diagnostic Tests: OUR TECHNOLOGY
At PRESBIT, we have the most advanced technology for the early diagnosis and treatment of different forms of Age-Related Macular Degeneration (AMD). OCT (Optical Coherence Tomography), fundus autofluorescence, color retinography, fluorescein angiography, microperimetry, multifocal electroretinogram (MREG), and ocular ultrasound will allow for the correct diagnosis, monitoring, and follow-up of the different stages of the disease.
These are some of the mutual insurance companies and health insurance providers we work with. However, the agreement with these mutual insurance companies will depend on the healthcare center.
If your policy doesn’t appear on the list, please don’t hesitate to contact us for more information.
