Eye The eye is one of the most complex and important sensory organs in the human body. It provides the ability to see in both bright and dim light, focusing on objects both near and far. Its three types of cone cells are able to distinguish millions of distinct colors and produce the high quality images that the body relies on for many daily activities.

Eye Nearsightedness: Vision disorder caused by an eyeball that is too long or a lens that is too strong; objects up close are seen easily while those far away appear blurry. Pupil: Adjustable opening in the center of the iris through which light enters the eye. Retina: Photosensitive lining inside the eye. Rods: Light-sensitive nerve cells of the retina that function chiefly in dim light. Sclera: Tough, fibrous outer covering (the white) of the eyeball.

About the eye The iris is the ring of pigmented tissue surrounding the pupil that varies in color. The iris opens and closes to control the amount of light entering the eye through the pupil. The pupil is the opening in the center of the iris where light enters the eye. When looking at the eye, the pupil appears black. In dim light, the opening in the center of the iris expands to allow more light to enter the pupil.

The Iris The iris, visible through the clear cornea as the colored disc inside of the eye, is a thin diaphragm composed mostly of connective tissue and smooth muscle fibers. It is situated between the cornea and the crystalline lens. The. texture, and patterns of each person s iris are as unique as a fingerprint.

Print Options Smaller (thinner) axons are more likely to bear myelin sheaths than larger (thicker) axons. Axons use chemically gated ion channels to generate graded potentials. Neurons can have multiple axons but only one dendrite. A neuron can have only one axon, but the axon may have occasional branches along its length.

Glossary of Eye Conditions A cleft or gap in some part of the eye, such as the iris, lens, or retina, that is caused by a defect in the development of the eyeball. How much coloboma affects a person's vision depends on the size and location of the cleft and on whether it occurs in one or both eyes.artial or complete absence of the iris of the eye. This rare condition, usually present at birth, results in impaired vision and sensitivity to light. People with aniridia are also at high risk for certain other eye conditions, such as glaucoma, nystagmus, and cataracts.

Restore and Maintain Good Vision and Eye Health Naturally Glaucoma (Definition). Glaucoma refers to a group of eye conditions that lead to damage to the optic nerve, the nerve that carries visual information from the eye to the brain. In many cases, damage to the optic nerve is due to increased pressure in the eye, also known as intraocular pressure (IOP).

Adnexal Torsion Q. What is adnexal torsion? A. Adnexal torsion is twisting of the ovary and/or fallopian tube (the adnexa) that results in obstruction of the normal blood flow to the ovary. Lack of blood flow initially causes pain and eventually can result in necrosis (death of the cells) of the ovary.dnexal torsion is an infrequent but serious cause of acute (sudden onset) abdominal pain. Studies have shown that adnexal torsion accounts for 2.5% of all gynecologic surgical emergencies in the United States.

- Definition: Adnexal Mass. An adnexal mass is a growth or lump next to the uterus, most commonly arising from the ovary or fallopian tube. These masses are usually benign, but can be cancerous. An adnexal mass refers to an abnormal mass of tissue that could be cystic or solid in the region near the ovaries. It can help to think about what other structures live in this region of the body when thinking of the possibilities for masses in this area.

Pupil The pupil is a hole located in the center of the iris of the eye that allows light to strike the retina.It appears black because light rays entering the pupil are either absorbed by the tissues inside the eye directly, or absorbed after diffuse reflections within the eye that mostly miss exiting the narrow pupil.he iris is a contractile structure, consisting mainly of smooth muscle, surrounding the pupil. Light enters the eye through the pupil, and the iris regulates the amount of light by controlling the size of the pupil.
