Retina Introduction
Why the Retina is So Important
Your retina is a thin, light-sensitive tissue located at the back of your eye. Filled with millions of photoreceptor cells called rods and cones, the primary responsibility of the retina is to control how you see images. Rods allow you to see in dim lighting conditions while cones help you see in daylight and decipher colors.
Healthy Retina
In a healthy eye, light energy is sent through the cornea of the eye and focused on the retina. The retina converts the energy into electrical impulses that are transmitted through the optic nerve to the brain. Those impulses are then translated into images for you to understand.
The macula is located in the center of the retina. A healthy macula will allow you to have clear central vision.
Damaged Retina
Any damage to the retina or macula will affect how light energy is received and transferred to the brain. Central vision problems as well as overall blurriness, spots and even blindness can occur when there is any deterioration of cells, retinal detachment, tears, puckers or any type of damage to this sensitive area.
Regular eye exams are vital for keeping a close watch on the health of your retina so signs of trouble can be identified as early as possible. Schedule a retina exam in Phoenix with us today.
What is the Macula?
A small yellowish area lying slightly lateral to the center of the retina that constitutes the region of maximum visual acuity and is made up almost wholly of retinal cones.
What is the Vitreous?
The clear colorless transparent jelly that fills the eyeball posterior to the lens, is enclosed by a delicate hyaloid membrane, and in the adult is nearly homogeneous but in the fetus is pervaded by fibers with minute nuclei at their points of junction.
