Retina

The retina is a thin layer of cells at the back of the eyeball of vertebrates and some cephalopods; it is the part of the eye which converts light into nervous signals.

Retinal anatomy

The human retina has ten distinct layers:

• Retinal pigment epithelium (RPE)
• Photoreceptor layer
• External limiting membrane - Layer of the retina that separates the inner segment portions of the photoreceptors from their cell nuclei.
• Outer nuclear layer
• Outer plexiform layer - In the macular region, this is known as the Fiber layer of Henle.
• Inner nuclear layer
• Inner plexiform layer
• Ganglion cell layer
• Nerve fiber layer
• Inner limiting membrane
