Medical Definition of Macula lutea

1. 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 characterised by the presence of a yellow pigment diffusely permeating the inner layers, contains the fovea centralis in its centre, and provides the best phototopic visual acuity. It is devoid of retinal blood vessels, except in its periphery, and receives nourishment from the choriocapillaris of the choroid. (12 Dec 1998)
