| retina |
[TA] the innermost of the three tunics of the eyeball, surrounding the vitreous body and continuous posteriorly with the optic nerve. It is divided into the pars optica, which rests upon the choroid, the pars ciliaris, which rests upon the ciliary body, and the pars iridica, which rests upon the posterior surface of the iris. The pars optica is subdivided into an outer, pigmented layer (pars pigmentosa) and an inner, transparent layer (pars nervosa). The pars nervosa is divided into nine layers, as follows (see illustration): (1) the internal limiting membrane; (2) the nerve fiber layer; (3) the layer of ganglion cells; (4) the inner plexiform layer; (5) the inner nuclear layer; (6) the outer plexiform layer; (7) the outer nuclear layer; (8) the external limiting membrane; (9) the layer of rods and cones. The layer of rods and cones is the percipient part of the retina, responding to visual stimuli by a photochemical reaction; it is connected with the nerve fiber layer by nerve fibers that join to form the optic nerve. In the center of the posterior part of the retina is the macula lutea, the most sensitive portion of the retina, with the fovea centralis at its center. About 0.25 cm inside the fovea is the point of entrance of the optic nerve and the central artery of the retina; at this point the retina is incomplete and forms the blind spot.
