Surgeons Offer New Treatment For Degenerative Eye Disease The dry type may set the stage for the less common but more severe wet form in which blood vessels and scar tissue begin to grow abnormally beneath the retina, leading to permanent damage of the macula. The macula is located at the center of the retina, the light-sensitive tissue lining the back of the eye. The retina converts light, or images, into nerve impulses that are carried to the brain via the optic nerve. People with AMD may gradually lose their central vision, which can seriously impact their quality of life.

Retinal Detachment: What Is a Torn or Detached Retina? The retina is the light-sensitive tissue lining the back of our eye. Light rays are focused onto the retina through our cornea, pupil and lens. The retina converts the light rays into impulses that travel through the optic nerve to our brain, where they are interpreted as the images we see.

Retina It is located near the optic nerve. The purpose of the retina is to receive light that the lens has focused, convert the light into neural signals, and send these signals on to the brain for visual recognition. The retina processes light through a layer of photoreceptor cells.

- The eye is like a camera. Light passes through the cornea and the pupil at the front of the eye and is focused by the lens onto the retina at the back of the eye. The cornea and lens bend light so it passes through the clear substance (vitreous gel) in the back chamber of the eye and is projected onto the retina. The retina converts light to electrical impulses. The optic nerve carries these electrical impulses to the brain, which converts them into the visual images that you see.

- For instance, our eyes receive and convert light waves into electrical energy which are transmitted to the visual cortex of the brain to create the sensation of vision and subsequently leading to perception. But each sense receptor requires a minimum level of energy to excite it before perception can take place.

Optic nerve Optic nerve. The optic nerve is located in the back of the eye. It is also called the second cranial nerve or cranial nerve II. It is the second of several pairs of cranial nerves. The job of the optic nerve is to transfer visual information from the retina to the vision centers of the brain via electrical impulses. The optic nerve is made of ganglionic cells or nerve cells. It consists of over one million nerve fibers. Our blind spot is caused by the absence of specialized photosensitive (light-sensitive) cells, or photoreceptors, in the part of the retina where the optic nerve exits the eye.

Retina the innermost light-sensitive membrane covering the back wall of the eyeball; it is continuous with the optic nerve 6 layers of cells that line the back of the eyeball.   … One layer is sensitive to light and is the first step in turning light into vision.t is the only part of the CNS that can be imaged directly.   The retina is a complex, layered structure with several layers of neurons interconnected by synapses. The only neurons that are directly sensitive to light are the photoreceptor cells.

Retina Anatomy The retina is the light-sensitive tissue that lines the inside of the eye. The retina functions in a manner similar to film in a camera. The optical elements within the eye focus an image onto the retina of the eye, initiating a series of chemical and electrical events within the retina.

- The layer of cells at the front of the retina contains the retinal ganglion cells, whose axons pass across the surface of the retina, collect in a bundle at the optic disc, and leave the eye to form the optic nerve.

The retina The retina. The retina is the nervous tissue in the back and sides of the eye about 25 cm 2 in size and between 0.2 and 0.4 mm thick (except the fovea which is thinner), composed of layers of different types of photoreceptors (rods and cones) and neurons.

Eye In most vertebrates and some molluscs, the eye works by allowing light to enter and project onto a light-sensitive panel of cells, known as the retina, at the rear of the eye. The cone cells (for colour) and the rod cells (for low-light contrasts) in the retina detect and convert light into neural signals for vision.

Corneal Disease The lens in turn focuses the light rays onto the retina, lining the back of the eye. The retina converts the image formed by the light rays into nerve impulses. The optic nerve, composed of the axons of the, then transmits these impulses from the eye to the first visual relay in the brain.

How do your eyes work? 1 Behind the pupil is the lens, a clear part of the eye that further focuses light, or an image, onto the retina. 2  The retina is a thin, delicate, photosensitive tissue that contains the special “photoreceptor” cells that convert light into electrical signals.

Types of Eye Problems Find an ophthalmologist near you ». The cornea is a layer of clear tissue at the front of the eye that helps focus light. Located at the corner of each eye, tear ducts drain tears secreted by the lacrimal gland to the surface of the eye. Tears keep the cornea lubricated and clear of debris. The colored part of the eye is the iris. It is a muscle that controls the pupil, the opening in the middle of the eye that controls the amount of light coming in. The lens is behind the pupil and focuses light onto the retina, the light-sensitive cells on the back of the eyeball. Acting much like the film in a camera, the retina converts images into electrical signals that are sent to the optic nerve.

Thin layer of tissue covering the front of the eye, except t The Retina. The retina is a light-sensitive layer at the back of the eye that covers about 65 percent of its interior surface. Photosensitive cells called rods and cones in the retina convert incident light energy into signals that are carried to the brain by the optic nerve.ptic Nerve. The optic nerve is the cable of nerve fibers with carries the electrical signals from the retina to the brain for processing. The point of departure of that optic nerve through the retina does not have any rods or cones, and thus produces a blind spot.

Central Serous Retinopathy When you look at something, light passes through the front of your eye, and is focused by the lens onto your retina. The retina is a delicate tissue that coats the inside of your eye. The retina converts the light into electrical signals that travel along the optic nerve to your brain.

- The Retina. The retina is a light-sensitive layer at the back of the eye that covers about 65 percent of its interior surface. Photosensitive cells called rods and cones in the retina convert incident light energy into signals that are carried to the brain by the optic nerve. thin layer (about 0.5 to 0.1mm thick) of light receptor cells covers the inner surface of the choroid. The focused beam of light is absorbed via electrochemical reaction in this pinkish multilayered structure. The human eye contains two kinds of photoreceptor cells; rods and cones.
