What is macular degeneration and how to know if I have it?

Over the years, our vision can change, and it becomes common to put on our reading glasses for the newspaper or to watch television. These changes are relatively normal; but if it worsens acutely, you could possibly be suffering from macular degeneration, which is one of the most common causes of blindness that affects approximately 30% of people over 75 years of age.

Macular degeneration is the progressive deterioration of vision, caused by lesions in the blood vessels of the macula: a central area of ​​the retina responsible for perceiving the detailed portrayals around us. The appearance of the disease is due to factors such as genetic predisposition, aging, tobacco use, obesity, poor eating and lifestyle habits, and ultraviolet radiation that comes from Smartphone screens, computers, and LED lights.

This disease is not accompanied by pain, but there are symptoms that you should recognize, including:

  • Blurred vision when performing daily tasks such as driving, typing, and walking.

  • Difficulty focusing on faces.

  • Light sensitivity.

  • Loss of perception of distance and height (going up and down stairs).

  • Dark spots in the center of the visual field that can become larger over time.

  • Perceiving colors with less intensity.

The diagnosis is confirmed by the ophthalmologist, and early treatment is necessary to minimize visual sequelae.

At Alpha Research Institute, we currently have a clinical study that allows us to contribute to the investigation of this disease and seek treatments that help improve the well-being of patients.
