How many fluids are in the eye




















This is called a torn or detached retina and can cause permanent vision loss. Problems with the aqueous or vitreous humors are potentially very dangerous because there are few early warning signs.

Patients generally do not notice any serious symptoms until damage has already begun. That is why it is no important that you come in to Georgia Eye Physicians and Surgeons for comprehensive medical eye exams on a regular basis, particularly if you are over the age of fifty when vitreous disorders become more common. If you have any concerns about your vision, or any questions about how to best maintain the health of your eyes, please contact Georgia Eye Physicians and Surgeons to schedule an eye exam with Dr.

Some of the neurons of the neural retina are specialized cells called photoreceptors. There are 2 types of photoreceptors — rods and cones. Rods and cones are sensitive to light and work together like a camera to capture information about what we see.

Other neurons in the neural retina process some of the information about what we see and send it to the optic nerve. The optic nerve then sends this information to the brain to finish processing. The lens is a transparent disc-shaped structure in the inner part of the eye.

It lies directly behind the cornea and iris. The lens changes its shape to allow the eye to focus on near or far objects.

Light rays pass through the lens and are focused on the retina to create images of objects at different distances from the body. The accessory adnexal parts of the eye include the eyelids, conjunctiva and lacrimal tear glands.

They protect, lubricate and support the eyeball. The eyelid is a fold of skin that covers and protects the eye. Muscles around the eye raise and close the eyelid. The eyelid has sebaceous glands that make an oily secretion that prevents the watery film on the eye from evaporating and the eyelid from sticking together.

The eyelid works like a windshield wiper that helps to lubricate the eye and keep the surface of the eye free of dust and other debris. The eyelashes grow from the edges of the eyelid.

They also help protect the eye from dust and debris. The conjunctiva is a clear mucous membrane that covers the inner surface of the eyelid and the outer surface of the eye. The conjunctiva secretes a watery fluid mucus that helps lubricate the eyeball and keep it moist.

The lacrimal gland also called the tear gland is located at the upper, outer corner of the eye. It secretes a watery fluid that makes up tears. Small ducts drain tears from the lacrimal gland through very tiny openings inside the inner corner of the eyelid. When the eye blinks, the tears are swept across the surface of the eye.

Tears lubricate the conjunctiva covering the surface of the eye and inner eyelid. Tears also remove dust and debris from the eye and help to prevent infection.

The eye socket orbit is a bowl-shaped area made up of bone formed from the skull. The iris, a muscle, is the colored part of the eye that contracts and expands to let light into the eye. At the center of the iris is a hole covered by the clear cornea called the pupil, where light enters the eye.

The lens inside our eye focuses this light onto the back of the eye, which is called the retina. The optic disc is the area on the retina where all the nerve fibers come together to become the optic nerve as it leaves the eye to connect to the brain. The front part of the eye is filled with a clear fluid called aqueous humor made by the ciliary body. The fluid flows out through the pupil.

Proper drainage helps keep eye pressure at a normal level and is an active, continuous process that is needed for the health of the eye. You have millions of nerve fibers that run from your retina to form the optic nerve.

These fibers meet at the optic disc. As the fluid builds up, it causes pressure to build inside the eye, which can damage these sensitive nerve fibers and result in vision loss. As the fibers are damaged and lost, the optic disc begins to hollow and develops a cupped shape. Doctors can identify this cupping shape in their examinations. If the pressure remains too high for too long, the extra pressure on the sensitive optic disc can lead to permanent vision loss.

Although high IOP is clearly a risk factor for glaucoma, we know that other factors also are involved because people with IOP in the normal range can experience vision loss from glaucoma. Identifying these other factors is a focus of current research. Glaucoma usually occurs in both eyes, but increased eye pressure tends to happen in one eye first. This damage may cause gradual visual changes and loss of sight over many years.
