Dégénérescence maculaire

Overview of Macular Degeneration

Macular Degeneration is a progressive eye disease that affects the macula, which is the central part of the retina responsible for sharp, straight-ahead vision. It is one of the leading causes of vision loss in people over the age of 50, often referred to as Age-Related Macular Degeneration (AMD). It can appear in two main forms: dry AMD and wet AMD. While dry AMD progresses slowly, wet AMD can lead to sudden vision loss due to abnormal blood vessel growth under the retina.

Types of Macular Degeneration

1. Dry Age-Related Macular Degeneration (Dry AMD): The most common form, where the macula gradually thins and small yellow deposits (drusen) accumulate.

2. Wet Age-Related Macular Degeneration (Wet AMD): Less common but more severe, involving leakage from abnormal blood vessels.

3. Stargardt's Disease (Juvenile Macular Degeneration): A genetic form often seen in younger individuals, linked to macular dystrophy.

Symptoms of Macular Degeneration

Blurred or distorted central vision.

Straight lines appearing wavy or crooked.

Difficulty reading or recognizing faces.

Dark, blurry areas in the center of vision.

Colors appearing faded or less vibrant.

Needing brighter light for close-up tasks.

Slow recovery of vision after bright light exposure.

Causes of Macular Degeneration

Aging is the primary cause in age-related cases.

Genetic factors (hereditary risk of macular dystrophy or Stargardt's disease).

Smoking and cardiovascular diseases.

Prolonged exposure to ultraviolet or blue light.

Obesity and poor diet lacking antioxidants and vitamins.

Complications in Macular Degeneration

Severe loss of central vision impacting daily tasks.

Permanent vision loss if untreated, especially in wet AMD.

Increased risk of falls and injuries due to poor vision.

Emotional distress or depression from sudden lifestyle limitations.

Dependency on others for routine activities.

Risk Factors of Macular Degeneration

Age over 50.

Family history of AMD or retinal degeneration.

Smoking or long-term exposure to pollutants.

Hypertension, high cholesterol or heart disease.

Obesity and sedentary lifestyle.

Excessive sun exposure without eye protection.

Preventions of Macular Degeneration

Maintain a healthy diet rich in leafy greens, omega-3 fatty acids, and vitamins.

Use sunglasses that block UV and blue light.

Quit smoking to reduce risk significantly.

Regular eye checkups after the age of 40.

Manage chronic conditions like diabetes and hypertension.

Engage in physical activities to improve blood circulation.
