The fovea is a small depressed region at the center of the macula, the central area of the retina. There, the inner retinal layers are shifted aside, allowing light to pass unimpeded to the photoreceptors. Only tightly packed cones, and no rods, are present at the foveola, the center of the fovea. The elongated axons of these cone cell bodies are called Henle fibers. The fovea is the region of maximum visual acuity.
