TY - CHAP M1 - Book, Section TI - Chapter 31. Disorders of the Retina A1 - Lueder, Gregg T. PY - 2011 T2 - Pediatric Practice: Ophthalmology AB - The retinal is a multilayered structure that lines the inside of the back of the eye. Light rays are focused on the retina by the cornea and lens. When they reach the retina, they cause chemical reactions in the deepest layer of the retina, the rods and cones (photoreceptors). This creates an impulse that is transmitted through the middle layer of the retina (the bipolar cells) to the inner portion (the ganglion cells) (Figure 31–1). The ganglion cells then travel and coalesce in the posterior portion of the eye to form to the optic nerve, which transmits the impulses to the brain. The retina is analogous to the film in a camera, in that it senses and changes in reaction to light.
