Dry macular degeneration is the most common form of age-related macular degeneration (AMD) and it causes a gradual loss of central vision. It’s characterized by the breakdown of light-sensitive cells in the macula, the central part of the retina.
Symptoms:
Blurred vision: Objects in the center of vision may appear blurry or distorted.
Reduced central vision: Difficulty reading, recognizing faces, or seeing fine details.
Increased light sensitivity: The need for more light to read or do close-up work.
Dimmed colors: Colors may appear faded.
Blind spot: A blurry spot or blind spot may appear in the center of vision, which can grow larger over time.
Causes:
Age: Age is the biggest risk factor for AMD, with the condition becoming more likely after 55.
Genetics: A family history of AMD increases the risk.
Lifestyle factors: Smoking, high blood pressure, high cholesterol, obesity, high sun exposure, and a diet low in antioxidants can increase the risk.
Progression:
Slow and gradual: Dry AMD typically progresses slowly over years.
May progress to wet AMD: In some cases, dry AMD can progress to the more severe wet form, which can cause rapid vision loss.
