Age-related macular degeneration
Age-related macular degeneration (AMD) is the main cause of irreversible vision loss in developed countries in people over the age of 55.
AMD, as its name indicates, is a progressive degeneration of the central region of the retina called the macula.
The macula is responsible for central vision, necessary for everyday activities such as reading, driving, identifying people, etc.
Types of AMD
There are 2 types of AMD:
- Dry form: this is the most common type, affecting approximately 80-90% of people who suffer from AMD. The loss of vision is very slow.
- Wet form: this is the least common form (10-20%), but it is the most severe because the loss of vision is very fast.
Risk Factors
- Age is the most significant risk factor. Although in general it occurs in people over the age of 65, there are also cases starting from the age of 55.
- Genetic factors that predispose to suffering from the disease.
- Smoking.
- Exposure to sunlight.
- Iris colour (light-coloured eyes more than dark-coloured eyes).
- Deficit of natural nutrients present in the retina.
How do I know if I am suffering from AMD?
- If you notice a progressive reduction in vision (days or weeks)
- Distorted perception of images.
- Appearance of dark spots in the central field of vision.
These symptoms must be assessed by an ophthalmologist, given that they can be the initial symptoms of AMD.
Recommendations for the Prevention of AMD
1.- Stop smoking
2.- Protection from the sun
Avoid the direct action of the sun's rays in the eyes using good sunglasses with UVA/UVB protection
3.- Check-ups
Visit your ophthalmologist regularly from the age of 55, especially if you have any family history of the condition.
4.- Diet
Published scientific studies have demonstrated how the daily intake of some nutrients prevent the risk of suffering from AMD. The nutrients studied are vitamins C and E, zinc, copper, lutein and zeaxanthin and omega-3 fatty acids: EPA and DHA
Treatment
For dry AMD, primary PREVENTION and the prevention of the disease's progression is very important. It is important to modify the risk factors when possible (smoking, diet, sunlight exposure, etc.)
For wet AMD, in recent years drugs known as anti-VEGF (anti-angiogenic agents) have emerged that are administered in the form of injections.
Como puedo saber si padezco DMAE
- Si percibe una disminución de la visión progresiva (días o semanas).
- Percepción distorsionada de las imágenes.
- Aparición de mandas oscuras en el campo central de la visión.
Estos síntomas deben ser evaluados por un oftalmólogo, puesto que pueden ser los síntomas iniciales de una DMAE.
Para la DMAE Seca es muy importante la PREVENCION primaria y la prevención de la progresión de la enfermedad. Es importante modificar los factores de riesgo cuando sea posible (tabado, dieta, exposición solar, etc)
Para la DMAE húmeda en los últimos años han aparecido fármacos conocidos como anti-VEFG (antiangiogénicos) que se administran en forma de inyecciones.
Recomendaciones Para la Prevención de la DMAE
- El Tabaco.
- Protección frente al sol.
- Evitarla acción directa de los rayos solares en los ojos usando buenas gafas de sol con protección UVA/UVB.
- Revisiones.
- Visitar periódicamente a su oftalmólogo a partir de los 55 años, sobre todo si tiene algún antecedente familiar que haya sufrido la enfermedad.
- La Dieta.
Estudios científicos publicados han demostrado cómo la ingestas diarias de algunos nutrientes previene el riesgo de padecer DMAE. Los nutrientes estudiados son las vitaminas C y E, el zinc, el cobre, la luteína y la zeaxantina y los ácidos grasos omega 3: EPA y DHA
