Strabismus
|
|
Strabismus Misaligned eyes. See exotropia, esotropia and hyperopia.
RELATED TERMS--------------------------------------
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.
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.
Hyperopia
Hyperopia (or more rarely, hypermetropia), also known as farsightedness or longsightedness, is a defect of vision caused by an imperfection in the eye (often when the eyeball is too short), causing inability to focus on near objects, and in extreme cases causing a sufferer to be unable to focus on objects at any distance. As an object moves towards the eye, the eye must increase its power to keep the image on the retina.
SIMILAR TERMS--------------------------------------
Strain
A partial or complete tear of a muscle or tendon.

PREVIOUS AND NEXT TERMS--------------------------------------
Sclera
The sclera is the white part of the eye. The clear cornea is the front extension of the sclera.
Scotoma
An absence of vision in part of the visual field. It is present in such conditions as glaucoma, or in more serious diseases within the brain. Often detected by a visual field test.
Snellen chart
The familiar eye chart with larger letters at the top and smaller ones at the bottom. It is used for measuring central vision.
Staphyloma
An abnormal bulging of the cornea or sclera. It is usually a congenital problem.
Stereopsis
Also known as depth perception. The separation between the eyes provides for slightly different views of an object by each eye. The brain for the purpose of telling the location of an object in 3D space uses this difference in views between the eyes or disparity.
Strabismus
Stargardt’s disease
Also called Juvenile macular degeneration. Early in the course of the disease the retina may look normal to the eye doctor. Later in the disease process, there is a total loss of the RPE and photoreceptors in the macula. Disease progression is rapid leading to a central scotoma, reduced central vision leading to legal blindness and some loss of color vision by the age of 20 years. Patients sometime become photophobic. No treatment is available. Also see dominant progressive foveal dystrophy.
Sex pheromones
Pheromones that elicit sexual attraction or mating behavior usually in members of the opposite sex in the same species.
Sex steroid binding protein
A glycoprotein migrating as a beta-globulin. The protein binds testosterone, dihydrotestosterone, and estradiol in the plasma
Sexology
The totality of characteristics of structures and functions differentiating the male from the female organism. It includes sexology, the study of the differences and interactions between the sexes. It does not include various sexual factors in epidemiology and statistics or the role of the sexes or differences in behavior, psychology, and sociology.
Sezary Syndrome
A form of cutaneous T-cell lymphoma manifested by generalized exfoliative erythroderma, intense pruritus, peripheral lymphadenopathy, and abnormal hyperchromatic mononuclear cells in the skin, lymph nodes, and peripheral blood.
