Enucleation
|
|
Enucleation An operation in which the whole eye and the front part of the optic nerve are removed. It is usually performed when the eye contains a tumor or is blind and very painful.
RELATED TERMS--------------------------------------
Nerve
Tissue that conveys sensation, temperature, position information to the brain.
Tumor
Overgrowth of tissue.
Blind
1. Unable to see. Without part or all of the sense of sight.2. In a clinical trial, not to know the treatment given or received. The participant is not told whether they are in the experimental or control arm of the study. Also called masked.
SIMILAR TERMS--------------------------------------
PREVIOUS AND NEXT TERMS--------------------------------------
Estrapak
Medication used in the treatment of vasomotor symptoms associated with menopause.
Exelon
Medication used in the treatment of dementia of Alzheimer's Disease.
Electroretinogram
ERG. A test that measures the functional integrity of the retina, including the rod and cone photoreceptors. Usually involves the use of dilating drops in the eye and use of a contact lens electrode.
Electrooculogram
EOG. A test of the functional integrity of the Retinal Pigment Epithelium (RPE) – a layer of cells next to the retina of the eye. The EOG involves electrodes attached to the inner and outer corners of the eye and the patient is required to look back-and-forth between two small lights in a large white globe (ganzfeld) with bright lights on and off.
Endophthalmitis
An inflammation involving the internal parts of the eye – i.e., choroid, retina, ciliary body and iris. A very serious condition sometimes seen after an injury to the eye by a foreign object. Vision is severely threatened. Large doses of cortisone and antibiotics are often needed. May lead to the removal of the eye. Must be treated by an eye doctor ASAP.
Enucleation
Esophoria
A tendency for an eye to turn inward a little bit. It occurs under certain conditions such as fatigue. An esophoria is sometimes uncovered by the cover test.
Esotropia
Commonly known as "crossed eyes". One eye is constantly turned inward toward the nose. In children, esotropia may lead to suppression of the visual signals from the eye to the brain and lead to amblyopia and decreased depth perception. In adults with previously straight eyes (for example after head trauma), esotropia causes constant double vision.
Exophoria
A tendency for an eye to turn outward a little bit. Occurs sometimes under certain conditions such as fatigue, bright sun light or prolonged use of the eyes.
Exophthalmos
An abnormal protrusion of the eyeball often caused by thyroid disease or a tumor behind the eye. Medical treatment is necessary.
Exotropia
Sometimes called "Wall Eyes". One eye is constantly turned outward. A child may have an exophoria which progresses to a stage where the eye is straight one minute and turned-out the next (as when daydreaming or in bright sunlight). This is called intermittent exotropia. May need surgical correction.
