Macula lutea
Macula lutea
The Macula lutea (pronounced: /ˈmakjʊlə ˈluːtiːə/), also known as the yellow spot or simply macula, is a specialized area in the retina of the eye that is responsible for sharp, detailed central vision.
Etymology
The term "macula lutea" comes from the Latin words "macula" meaning "spot" and "lutea" meaning "yellow". This is due to the yellowish color of the macula, which is visible upon direct examination of the retina.
Function
The macula lutea is the region of the retina that contains the highest concentration of cone cells, which are the photoreceptor cells responsible for color vision. The central part of the macula, known as the fovea, contains only cone cells and is the point of sharpest vision.
