Definition : An oval area in the retina, 3 to 5 mm in diameter, usually located temporal to the
posterior pole of the eye and slightly below the level of the optic disk. It is characterized
by the presence of a yellow pigment diffusely permeating the inner layers, contains
the fovea centralis in its center, and provides the best phototropic visual acuity.
It is devoid of retinal blood vessels, except in its periphery, and receives nourishment
from the choriocapillaris of the choroid. (From Cline et al., Dictionary of Visual
