Fovea in retina

WebFovea: In the eye, a tiny pit located in the macula of the retina that provides the clearest vision of all. Only in the fovea are the layers of the retina spread aside to let light fall directly on the cones, the cells that give the sharpest image. … WebFovea In the human eye the term fovea (or fovea centralis) is the "pit" in the retina that allows for maximum acuity of vision. The human fovea has a diameter of about 1.0 mm with a high concentration of cone photoreceptors. Foveola The center of the fovea is the foveola – about 0.2 mm in diameter – where only cone photoreceptors are present.

WebThe retinal thickness of the fovea within the central 6° and the ODF angle are independent of the AL in healthy young Japanese. We suggest that there may be a physiological system to keep these structures stable and that the system may be related to the NVSMCs beneath the fovea and between the foveal and the optic nerve. The fovea is a depression in the inner retinal surface, about 1.5 mm wide, the photoreceptor layer of which is entirely cones and which is specialized for maximum visual acuity. Within the fovea is a region of 0.5mm diameter called the foveal avascular zone (an area without any blood vessels). This allows the light to be sensed without any dispersion or loss. This anatomy is responsible for the depression in the center of the fovea. The foveal pit is surrounded by the foveal rim that cont…
