The fovea contains no blood vessels. It receives its blood supply from the choroid, which is adjacent to the retinal pigment epithelium. This high cone density and absence of blood vessels enable the sharp vision provided by the human fovea. Conditions That May Affect the Fovea. A variety of eye problems can affect the fovea centralis.
Fovea centralis is a small pit in the retina with high visual acuity, composed of closely packed cones. It is located in the center of the macula lutea and responsible for sharp central vision, such as reading and driving.
The fovea is a small area of the retina that provides sharp, central vision and helps us see colors. Learn about the fovea's role, common eye problems that affect it, and how to treat them.
Learn about the fovea, the depression in the center of the macula where eyesight is sharpest. Find out the eye problems that can affect the fovea and cause vision loss.
The fovea centralis is located in the center of the macula lutea, a small, flat spot located exactly in the center of the posterior portion of the retina. As the fovea is responsible for high-acuity vision it is densely saturated with cone photoreceptors. The macula is about 5.5 mm in diameter, while the fovea is 0.35 mm in diameter.
Learn about the fovea, a tiny depression in the macula that provides the sharpest vision. Find out how the fovea works, what conditions may affect it, and why routine eye exams are important.
The fovea centralis is a specialized area of the retina that has the highest visual acuity. It is a depression within the center of the macula lutea, opposite the pupil, with the highest density of cone photoreceptor cells.
General features of the fovea. Looking at the retina lining the back of the eyeball in a human, we can see the clear landmark of the optic nerve head (papilla) and radiating blood vessels ().Temporal to the optic nerve head at a distance approximately 2.5 optic nerve (disk) diameters at roughly 3.4 mm distance lies a dark brown-yellowish area (), in the center of which is the tiny circular fovea.
In humans, the fovea centralis (hereafter referred to as the fovea, from the Latin for 'pit') is a morphologically distinct region of the retina named for its excavated appearance . It samples a circular region of the visual field about 1° in diameter — only twice the diameter of the image on the retina of the full moon.
The fovea is a tiny depression in the retina that contains a high concentration of cones, which are responsible for color and detail vision. Learn about the fovea's function, location, and how it can be affected by various conditions.
