San Diego Doctors Discuss Retina Disorders
The retina is a layer of the eye that is sensitive to light and dwells in the back of the eye. Rods and cones in the retina, which are photosensitive cells, convert light into signals that are sent to the brain by the optic nerve. The center of the eye is where the best vision [...]

Eye Function The eye works much like a camera. Like the eye, a camera produces images by focusing light to create a visual impression on film. In vision, light enters the eye through the cornea, which with the lens focuses the image onto the retina where it is then transferred to the brain via the [...]

Looking at an eclipse is as dangerous as staring at the unblocked sun, and can cause damage to the retina, the light sensitive nerve layer at the back of the eye. The damage affects the macula, the part of the retina responsible for central vision.

Tuesday, September 19, 2006
Comments Off
PTK is an excimer laser surgical procedure that removes roughness or cloudiness from the cornea. The cornea is the smooth clear window of the eye in front of the colored iris that helps bend light rays so they focus directly on the retina, the light-sensing layer of cells at the back of the eye. If [...]

Tuesday, September 19, 2006
Comments Off
To see clearly, light rays must be bent or refracted to focus on the retina, the light- sensitive nerve layer that lines the back of the eye. The cornea and lens of the eye work together to bend or refract light rays and bring them together on the retina. If a refractive error is present, [...]

Comments Off
Myopic degeneration is an uncommon condition characterized by progressive stretching of the eye that damages the retina, the layer of light-sensitive cells that lines the back of the eye. People with severe nearsightedness (high myopia) are at greater risk for myopic degeneration.

Comments Off
Vitrectomy is a type of eye surgery used to treat disorders of the retina (the light-sensing cells at the back of the eye) and vitreous (the clear gel-like substance inside the eye). It may be used to treat a severe eye injury, diabetic retinopathy, retinal detachments, macular pucker (wrinkling of the retina) and macular holes.

Comments Off
Stargardt’s is an inherited disease that affects the retina, the layer of light-sensitive cells lining the back of the eye. It usually becomes apparent between the ages of 8 and 14. Boys and girls are equally susceptible and more than one child in a family may have it.

Tuesday, September 19, 2006
Comments Off
Retinoschisis is a genetic eye disease that splits the retina, the light-sensitive layer of cells lining the back of the eye. It occurs in two forms, one affecting young children, the other older adults. Both forms usually affect both eyes, though one eye may be worse than the other.

Comments Off
Retinopathy of Prematurity (ROP) damages premature babies’ retinas, the layer of light-sensitive cells lining the back of the eye. ROP usually occurs in both eyes, though one may be more severely affected.
