Foveola is a term commonly used in ophthalmology to refer to the central depression or pit found in the macula of the human retina. Synonyms for this word include macular pit, central foveal depression, foveal avascular zone, and central fovea. The foveola is an important structure in the eye, responsible for sharp, clear vision and color perception. It is approximately 0.35 mm in diameter and contains a high concentration of photoreceptor cells. The harsh appearance of the foveola results in efficient cone packing, enabling humans to perceive small objects and fine details with exceptional accuracy.
