the macula (also known as macula lutea) is a small, oval-shaped area near the center of the retina in the human eye, responsible for sharp central vision (also called high-acuity vision). it contains a high concentration of photoreceptor cells, especially cone cells, essential for detailed vision, color perception, reading, and recognizing faces.
key functions:
detailed and sharp central vision
color perception
visual tasks like reading, driving, and face recognition
structure:
contains the fovea, a small central pit densely packed with cones for maximum visual acuity.
high concentration of carotenoids (lutein and zeaxanthin) that protect against oxidative stress and blue-light damage.
associated conditions:
age-related macular degeneration (AMD)
macular edema (swelling)
maintaining macular health (e.g., through diet rich in carotenoids) helps preserve clear, sharp central vision.
