Retina The retina is a thin layer of tissue that lines the back of the eye on the inside. 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. 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.

Detached Retina (Retinal Detachment) A detached retina occurs when the retina is pulled away from its normal position in the back of the eye. The retina sends visual images to the brain through the optic nerve. When detachment occurs, vision is blurred.A detached retina is a serious problem that can cause blindness unless it is treated.The retina normally lies smoothly and firmly against the inside back wall of the eyeball and functions much like the film in the back of a camera.hen detachment occurs, vision is blurred.

- From Middle English macula (“spot on the skin or in the eye”), borrowed from Latin macula (“spot, stain”). Noun. (anatomy) An oval yellow spot near the center of the retina of the human eye, histologically defined as having two or more layers of ganglion cells, responsible for detailed central vision.

Fovea centralis The fovea centralis (the term fovea comes from the Latin, meaning pit or pitfall) is a small, central pit composed of closely packed cones in the eye. It is located in the center of the macula lutea of the retina.ovea (or Fovea centralis) is the depression in the inner retinal surface, about 1.5 mm wide, the photoreceptor layer of which is entirely cones and which is specialized for maximum visual acuity.

- Fovea: In the eye, a tiny pit located in the macula of the retina that provides the clearest vision of all. Only in the fovea are the layers of the retina spread aside to let light fall directly on the cones, the cells that give the sharpest image.Also called the central fovea or fovea centralis. The word fovea is the Latin word for small pit.. The fovea is literally a small depression (in the retina).nly in the fovea are the layers of the retina spread aside to let light fall directly on the cones, the cells that give the sharpest image.

Medical Definition of Optic nerve The retina is the nerve layer that lines the back of the eye, senses light and creates impulses that travel through the optic nerve to the brain. The macula is a small area in the retina that contains special light-sensitive cells and allows us to see fine details clearly.

Retinal Detachment The retina is the light-sensitive layer of tissue that lines the inside of the eye and sends visual messages through the optic nerve to the brain. When the retina detaches, it is lifted or pulled from its normal position. If not promptly treated, retinal detachment can cause permanent vision loss.

- Definition. 1  Macular degeneration is the progressive deterioration of a critical region of the retina called the macula. The macula is a 3-5 mm area in the retina that is responsible for central vision.

- The retina is the light-sensitive layer of tissue at the back of the eye that senses light and sends images to the brain. If the retina pulls away from the back of the eye, it cannot function, and you experience a retinal detachment. A retinal detachment is a medical emergency that, without treatment, almost always causes blindness. Call Retina Vitreous Associates immediately to consult with a retina surgeon.

Macular Degeneration Home » Resources » Diseases & Disorders » Retinal Disorders » Macular Degeneration. The macula is the most central portion of the retina, directly opposite the lens. It is where the greatest number of light sensitive cells, called cones, are located. Cones allow us to see color and fine detail. The high concentration of cones in the macula gives people extremely detailed and rich central vision.

Girls Names From Stars and Constellations Carina is a constellation of the southern hemisphere; its name is Latin for “keel”, and it represents part of the ship, the Argo, sailed by Jason and the Argonauts in Greek legend. The most prominent star in the constellation is Canopus, the brightest star of southern skies, clearly visible and high in the sky.

- A corona (Latin, ' crown ') is an aura of plasma that surrounds the sun and other celestial bodies. The Sun's corona extends millions of kilometres into space and is most easily seen during a total solar eclipse, but it is also observable with a coronagraph.he sun's corona is much hotter (by a factor from 150 to 450) than the visible surface of the Sun: the photosphere 's average temperature is 5800 kelvin compared to the corona's one to three million kelvin. The corona is 10 −12 times as dense as the photosphere, and so produces about one-millionth as much visible light.

- Retinal detachment is a condition in which the retina is no longer stretched over the inner wall of the eye. Since the retina is no longer in its place, one can say that it has “fallen” or “collapsed”.

Eye health guide Most of the eye is filled with a clear gel called the vitreous. Light projects through the pupil and the lens to the back of the eye. The inside lining of the eye is covered by special light-sensing cells that are collectively called the retina.The retina converts light into electrical impulses. Behind the eye, the optic nerve carries these impulses to the brain.The macula is a small extra-sensitive area within the retina that gives central vision. It is located in the center of the retina and contains the fovea, a small depression or pit at the center of the macula that gives the clearest vision.ehind the eye, the optic nerve carries these impulses to the brain.

Macular Degeneration What is macular degeneration? Macular degeneration is an eye disease usually associated with aging that gradually diminishes central vision. Detailed vision is processed by the macula, which is the central part of the retina.When the macula becomes damaged many daily activities such as driving and reading become increasingly difficult.

Eye Conditions The retina is the nerve layer at the back of the eye that senses light and sends images to your brain. The eye is like a camera. The lens in the front of the eye focuses light into the retina. You can think of the retina as the film that lines the back of a camera. The centre of the camera film is called the macula. The vitreous is a gel that fills the inside of the eye.

What is Macular Degeneration? Basic Retina Anatomy Retina Anatomy. A basic overview of retina anatomy will help you better understand why and how this eye disease affects one’s vision. The best analogy for understanding how the eye works is to compare the eye to a camera. It is the back of the eyeball, the retina, that acts like film in a camera.The retina is a very thin layer of tissue lining the inside of the eye.he macula is a small spot, about the size of a pencil eraser, located in the center of the retina. This part of the retina is responsible for detailed, sharp, clear vision. A healthy macula is what gives a person 20/20 vision.
