Focal dystonia due to blepharospasm
|
|
Focal dystonia due to blepharospasmThe involuntary forcible closure of the eyelid due to spasms. The first symptoms may be uncontrollable blinking. Only one eye may be affected initially, but eventually both eyes are usually involved. The spasms may leave the eyelids completely closed causing functional blindness even though the eyes beneath the lids and vision are normal. Following torticollis (spasm of the neck muscles), blepharospasm is the next most common form of focal dystonia. For more information about dystonias, see: Dystonia.
RELATED TERMS--------------------------------------
Eyelid
The lid or cover of the eye, a movable fold of skin and muscle that can be closed over the eyeball or opened at will. Each eye has an upper and a lower lid. An eyelid is also called a palpebra.
Blindness
Legal blindness is defined as: 1) visual acuity of 20/200 (only being able to see the big E on the eye chart) or less in the best eye even with the eyes corrected by glasses or contact lenses; or, 2) The peripheral visual field is reduced to 20 degrees of visual angle or less. Twenty degrees of visual angle is about the size of a one foot ruler held at arms length.
Vision
The sense of sight.
Torticollis
Abnormal posture of the head due to spasm of the sternocleidomastoid muscle.
Blepharospasm
Excessive winking; tonic or clonic spasm of the orbicularis oculi muscle.
Focal
Limited to one specific area.
Dystonia
Dystonia is a neurological movement disorder with involuntary muscle contractions, forcing specific parts of the body into abnormal movements or positions, sometimes causing pain.
SIMILAR TERMS--------------------------------------
Focal
Limited to one specific area.
Focal dystonia due to torticollis
Spasm of the muscles in the neck that control the position of the head, causing the head to twist and turn to one side. In addition, the head may be pulled forward or backward. Torticollis is the most common form of focal dystonia.
Focal gigantism
1. The excessive growth of a specific body part such as a hand or foot, as with increased blood supply to that part. 2. The excessive growth of a combination of particular body parts, as is characteristic of a congenital malformation syndrome called the Wiedemann-Beckwith syndrome. Focal gigantism may occur before or after the bones fuse. If it occurs afterwards, it causes disfigurement, as in acromegaly. Surgery for mass reduction may sometimes improve function.
Focal length
Relates the distance between an image source and a lens and the distance of the lens to the image by the lenses focal length.
Focal motor seizure
A simple partial seizure with localized motor activity. There may be spasm or clonus (jerking) of one muscle or a muscle group and this may remain localized or it may subsequently spread to adjacent muscles as a Jacksonian seizure.
Focal vision
The role of vision involved in the examination and identification of objects associated with the fovea and exploratory eye movements.
Focalin
Integral part of total treatment program to stabilize ADHD/ADD.
Focalin xr
Focalin xr 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): dexmethylphenidate hydrochloride.
PREVIOUS AND NEXT TERMS--------------------------------------
FMDV
Foot-and-mouth disease virus.
FMF (familial Mediterranean fever)
An inherited disorder featuring short recurring crises of severe abdominal pain and bouts of fever. Other symptoms include arthritis, chest pain from inflammation of the lung cavity, and skin rashes. Between attacks, the patient seems healthy. Amyloidosis (the abnormal deposition of a particular protein, called amyloid, in various tissues of the body) is a potentially serious complication and can develop without overt attacks of FMF. The kidney is a prime target for the amyloid.
FMO3
Abbreviation for the enzyme, flavin-containing monooxygenase-3.
FMR1
The gene responsible for the production of a protein called FMRP. Lack of FMRP results in the fragile X syndrome. (FMRP is an acronym composed of the first letters of Familial Mental Retardation Protein).
FMRP
As stated in the entry for FMR1, FMRP is an acronym composed of the first letters of Familial Mental Retardation Protein.

Folate
Folic acid, one of the B vitamins that is a key factor in the synthesis (the making) of nucleic acid (DNA and RNA). A deficiency of folic acid after birth causes a kind of anemia, namely, megaloblastic anemia in which there is a paucity of red blood cells and those that are made are unusually large and immature (so-called blast cells).
Folding motif
An independent folding unit, or particular structure, that recurs in many molecules.
