Figure 2. Normal Retina

This image of a normal retina identifies important landmarks visible with a hand-held ophthalmoscope. The macula is in the center of the retina; it contains densely packed cones that specialize in visual acuity and color vision. The fovea is the central depression within the macula. The optic nerve functions to transmit impulses from the retina to the brain and the visible portion of the optic nerve is known as the optic nerve head or optic disc. Retinal veins and arteries are prominently seen extending from the optic nerve.
