macula
Eye's sharpest region
A macula is a spot or blemish, particularly a discolored patch on the skin.
In anatomy, the macula refers specifically to the macula lutea, a small yellowish area near the center of the retina responsible for sharp central vision: Macular degeneration is a leading cause of vision loss in older adults.
The plural is maculae or maculas.
