Fovea (redirected from foveiform)

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

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.

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.
