What Is Macular Degeneration and How Does It Affect Vision?
Macular degeneration is a medical condition that affects the macula, the central part of the retina, leading to vision loss. It typically causes blurred vision or a blind spot in the center of the visual field.
According to the American Academy of Ophthalmology, macular degeneration is defined as “a progressive eye disease that causes vision loss in older adults.” It occurs primarily in people over 50, making it a significant health concern for the aging population.
Macular degeneration can be classified into two main types: dry and wet. Dry macular degeneration is more common and progresses slowly. Wet macular degeneration involves abnormal blood vessel growth under the retina, which can lead to more rapid vision loss.
The National Eye Institute describes macular degeneration as a “leading cause of vision impairment in older adults,” highlighting its severity and prevalence.
Key risk factors include age, genetics, smoking, and diet. Individuals with a family history of the condition or those who smoke are more likely to develop macular degeneration.
About 2.1 million Americans had macular degeneration in 2020, and this number is projected to rise to 8 million by 2050, according to the BrightFocus Foundation. This increase underscores the pressing need for awareness and intervention.
Macular degeneration impacts not only vision but can also lead to emotional and psychological distress. Patients may struggle with daily activities and experience social isolation.
The condition affects healthcare systems and economies due to increased healthcare costs and loss of productivity. Early diagnosis and treatment are crucial to mitigate these impacts.
To address macular degeneration, the American Academy of Ophthalmology recommends regular eye exams and lifestyle modifications, such as a healthy diet rich in leafy greens and antioxidants.
Effective strategies include using vision aids, adopting specific visual rehabilitation practices, and exploring treatments like anti-vascular endothelial growth factor (VEGF) therapy for wet macular degeneration.
