Staphyloma
|
|
Staphyloma An abnormal bulging of the cornea or sclera. It is usually a congenital problem.
RELATED TERMS--------------------------------------
Abnormal
Not normal. Deviating from the usual structure, position, condition, or behavior. In referring to a growth, abnormal may mean that it is cancerous or premalignant (likely to become cancer).
Cornea
The front part of the eye that acts as a window for the entrance of light rays. It is attached to the other outer coat of the eye, the sclera; the white part of the eye. The cornea provides a significant amount of focusing power for the eye (the rest is provided by the lens). Because it has many nerve fibers, an injury or foreign body causes significant pain and discomfort.
Sclera
The sclera is the white part of the eye. The clear cornea is the front extension of the sclera.
Congenital
Present at birth.
SIMILAR TERMS--------------------------------------
Stapedectomy
Surgical removal of the stapes.
Stapedioplasty
Replacement of the stapes with other materials (wire, bone, plastic).
Stapes
A small bone of the middle ear. Also called the stirrup.
Staphcillin
Staphcillin is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): methicillin sodium.
Staphylococcus
Spherical gram-positive parasitic bacteria that tend to form irregular colonies; some cause boils or septicemia or infections.
PREVIOUS AND NEXT TERMS--------------------------------------
Sulpiride
An antipsychotic drug.
Secobarbital
A hypnotic substance.
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
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
Misaligned eyes. See exotropia, esotropia and hyperopia.
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
