Eye tumors may occur on the outside of the eye or on structures within the eye itself. In certain cases, you can see a tumor on the iris, the colored part of the eye, but others may grow in the back section of the eye. Eye cancer can affect people...
The functions of the eye are influenced by impulses from several nerves in the skull called cranial nerves. The optic nerve translates visual information from the retina into nerve impulses that the brain can interpret. The oculomotor nerve...
Tumors of the eye can be benign, meaning non-cancerous, or malignant. Malignant, or cancerous, tumors have the potential to travel to the eye from other parts of the body. According to Dr. David H. Abramson, recipient of the 2004 Mildred...
Eye cancer may occur in many parts of your eye. A tumor or cancerous lesion may grow on your eyelids, the surface of your eye or inside your eye. Eye cancer requires proper treatment to help you maintain the best possible vision and to prevent the...
A retinoblastoma tumor is a cancerous tumor that grows in the eye. The tumor begins growing on the retina, the lining in the interior of the eye. The retinoblastoma tumor is a rare cancer primarily found in children under the age of 5. The...
People often say that children are our most precious gift. And yet there are diseases they can contract. Some diseases can be prevented by immunizations; but unfortunately, there are other diseases that cannot be prevented. Among these are the...
Retinoblastoma is a medical condition that occurs if you develop a cancerous tumor within the retina---the delicate nerve tissue that lines the back of your eye. This type of cancer occurs most commonly in children under the age of five and is...
Some diseases are found more often in men than in women, while others seem to attack women in higher numbers than men. Some diseases may mainly affect a specific race or ethnic group. There are also diseases primarily seen in specific age groups,...
Epiphora, or tearing, can occur in one or both eyes, and can have multiple causes. According to the West Boca Eye and Cosmetic Center, the main causes of tearing are the production of too many tears due to irritation, infection or a blockage of...
The retinas of the eyes convert light into chemical signals that travel along the optic nerve and are interpreted by the brain, resulting in vision. Disturbances in vision can occur at the level of the eyes, the optic nerve, or the brain area that...
The eyes are responsible for taking in light and sending information to the brain about what they see. The visual system requires communication between the eyes and the nervous system. If the brain stops communicating with one eye, it can begin to...
The eye has a tissue that covers the surface. This tissue, called the conjunctiva, is much like the skin all over your body, and growths may appear with a slight color or no color at all. In many cases, these nodules do not cause problems, but a...
Skin conditions that affect the face also can form growths around the eyes. A doctor should investigate growths that are close to the eyes to prevent vision problems and to test for malignant tumors. According to the Children's Tumor Foundation,...
Brain tumors can affect the optic nerve itself and the cranial nerves that control eye movement. Tumors in different parts of the brain affect different nerves and often affect several nerves at once. According to "Adams and Victor's Principles of...
Glaucoma causes loss of peripheral vision due to damage to the retina and optic nerve. Risk factors include being over 60 years of age, having a family history of glaucoma and being of African American decent. The most common type of glaucoma,...
A bulging eye or eyes is called proptosis, and is caused by something taking up space inside of the eye socket and pushing the eye forward. This condition can be diagnosed by ultrasound, CT scan or MRI, though if possible, a biopsy of a piece of...
The term "lazy eye" describes a problem between neural pathways in the brain and eye that result in a loss of vision. Lazy eye exercises for adults are designed to strength the ocular muscles in an effort to correct a lazy eye. Although corrective...
Tumors inside the eye, often called ocular tumors, do not occur frequently, but when they do occur, they will typically grow on the colored part of the eye called the iris, or in the back of the eye. In the beginning, most ocular tumors do not...
Cancer can develop both in the eye and its surrounding tissues. The eye consists of the eyeball, the orbit and tissues around the eye like the eyelids and tear glands. Certain types of cancers like melanoma and retinoblastoma can originate in the...
Eye cancers occur in different parts of the eye and affect various types of cells. Eye cancer can be difficult to diagnose unless a person has regular eye exams. The most common type of eye cancer, retinoblastoma affects mostly children under the...
A protruding or bulging eye, also known as proptosis, may occur gradually, and a person may not recognize changes until the protrusion is significant. Eye protrusion may result in an inability to fully close the eyelids, causing damage to the...
Strabismus, an eye condition more commonly referred to as crossed eyes or lazy eye is a common phenomenon affecting about 5 percent of young children. Crossed eyes vary in severity, affecting some people all of the time, and others only when...
Ptosis, or drooping eyelid, can be caused by weakness of the eyelid muscles, looseness of the upper eyelid skin, or damage to the nerves that control your eyelid muscles. It can be hereditary or part of the normal aging process. You might be at...
The American Cancer Society estimates that more than 22,000 new cases of brain and other nervous system cancers will be diagnosed among Americans in 2010 alone. Although not always malignant, brain tumors can cause problems and pose a fatal threat...
Ocular melanoma is a type of cancer that arises from the cells in the eye that make melanin. Ocular melanomas can form from the pigmented cells of the iris, but the majority of ocular melanomas form in the back of the eye and are called choroidal...
Abnormal eye movements impact a person's appearance and visual function. The eyes may oscillate side to side---a condition called "nystagmus." Alternatively, the motion may be restricted or jerky, or the eye may appear to be wandering. Many...
Retinoblastoma is a type of cancer that affects the eyes in young children, but it can also sometimes occur in adults. Retinoblastoma can occur in one eye or both eyes, with cancerous tumors growing in the retina at the back of your child's eye....
The retina contains light-sensitive cells and other types of cells that transmit nerve impulses to the brain. When the retina becomes detached from the back of the eye, it peels away and affects vision. This can be caused by trauma to the eye,...
Retinoblastoma is an eye cancer that originates from cells of the retina. This cancer can occur in adults, but the vast majority of people who develop retinoblastoma are children. According to the Cleveland Clinic, between 200 and 300 children are...
Burkitt's Lymphoma is a specific lymphoma cancer that only effects certain B-cells that is very aggressive and tends to cause tumors and spread rapidly. Learn more about this rare but serious cancer in this video.
