What Causes Macular Degeneration?
Understanding Macular Degeneration
Macular Degeneration is a common eye condition that affects the macula, a crucial part of the retina at the back of the eye. The macula is responsible for processing light, enabling us to see sharp, detailed images. This condition typically does not manifest before age 40, with Age-Related Macular Degeneration (AMD) more commonly developing in individuals aged 55 and older.
Main Causes: Heredity and Age
Genetics play a significant role in Macular Degeneration, often running in families. While genetics are crucial, particularly in AMD, the simple aging process also contributes significantly. Scientists have identified specific genes, like complement factor H (CFH) and PLEKAH1 on chromosome 10, which are believed to influence the development of Macular Degeneration. Further research is necessary to fully understand their impact on the 10 million people affected over age 40.
In rare instances, when Macular Degeneration occurs in younger individuals, factors beyond genetics and age, such as myopia and infections, may lead to abnormal blood vessel growth behind the retina.
Other Investigated Causes
Several risk factors are associated with Macular Degeneration. Smoking has a notable impact, so quitting can reduce the risk. Age plays a crucial role, as the likelihood of developing symptoms increases with age. Gender and race also influence risk, with females and Caucasians being more susceptible than males and African Americans.
Studies are examining whether diet influences Macular Degeneration risk. Initial findings suggest a link between the disease and high saturated fat and cholesterol intake, as well as low antioxidant levels. Antioxidants, present in fruits and vegetables, help prevent cell damage by counteracting oxidation.
Exercise is another area of interest. Regular physical activity might reduce the risk by maintaining normal blood pressure, which is beneficial for mitigating AMD risk.
Finally, researchers are exploring the effects of direct sunlight exposure. It's wise to wear sunglasses while awaiting conclusive results.
By understanding these factors, individuals can take proactive steps to reduce their risk of developing Macular Degeneration and maintain eye health.
