fovea

 [fo´ve-ah] (pl. fo´veae) (L.)
a small pit or depression often used alone to indicate the central fovea of the retina.
central fovea of retina (fovea centra´lis re´tinae) a small pit in the center of the macula lutea, composed of slim elongated cones; it is the area of clearest vision, because here the layers of the retina are spread aside, permitting light to fall directly on the cones.

fo·ve·ae

(fō'vē-ă, fō'vē-ē), [TA]
Any natural depression on the surface of the body, such as the axilla, or on the surface of a bone. Compare: dimple.

fovea

/fo·vea/ (fo´ve-ah) pl. fo´veae   [L.] a small pit or depression. Often used alone to indicate the central fovea of the retina.
central fovea of retina  a small pit in the center of the macula lutea, the area of clearest vision, where the retinal layers are spread aside, and light falls directly on the cones.
submandibular fovea  a depression on the medial aspect of the mandible, lodging part of the submandibular gland.

fovea

fovea

Any shallow cup-like depression. The fovea centralis of the RETINA is the central area of the macula lutea, of highest resolution and free of visible blood vessels.

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.

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). See eccentricity; fixation; umbo.

fovea

pl. foveae [L.] a small pit or depression, usually in a bone, e.g. in the center of the articular surface of the head of the femur; often used alone to indicate the central fovea of the retina.

central fovea of retina, fovea centralis retinae
a small pit in the center of the macula lutea of the human and avian eye, composed of slim, elongated cones; it is the area of clearest vision.
