fovea

an area in the centre of the retina of the eye in which CONES are concentrated and RODS are absent (see Fig. 156 ). In humans, the fovea takes the form of a shallow pit about 1 mm in diameter, there being no layer of nerve fibres over it as there is in the rest of the retina. It occurs in primates, diurnal birds and lizards. It is an area of acute vision, and in BINOCULAR VISION the image of the object observed is focused on both foveae.

Fovea

A tiny pit in the macula that is responsible for sharp vision.Mentioned in: Macular Degeneration, Retinal Vein Occlusion

foveola

The base of the fovea centralis with a diameter of about 0.35 mm (or about 1º of the visual field). The image of the point of fixation is formed on the foveola in the normal eye. The foveola contains cone cells only (rod-free area). The foveal avascular zone is slightly larger (about 0.5 mm in diameter) (Fig. F9). Syn. fovea (term often used by clinicians).
