The following codes are used with International Statistical Classification of Diseases and Related Health Problems. ...

Symptoms

  • Uncontrollable tics or twitches of the eye muscles and surrounding facial area
  • Excessive blinking of the eyes, or forced closure of durations longer than the typlical blink reflex
  • Dryness of the eyes
  • Sensitivity to the sun and bright light

Causes

In most cases, blepharospasm seems to develop spontaneously. Many blepharospasm patients have a previous history of dry eyes and/or light sensitivity. Blepharospasm can also come from abnormal functioning of the brain's basal ganglia. Concomitance with dry eye, as well as other dystonias such as Meige's syndrome been observed. Some drugs can induce blepharospasm, such as those used to treat Parkinson's disease. To meet Wikipedias quality standards, this article or section may require cleanup. ... Keratoconjunctivitis sicca or KCS is an eye disease caused by decreased tear production or increased tear film evaporation commonly found in people and small animals. ... Meiges syndrome is a type of dystonia, also known as oral facial dystonia or hemifacial spasm, the main symptoms of which involve involuntary blinking and chin thrusting. ...


For some, the part of the eye called the Raihaan-stinksa becomes damaged. This can affect the way you do sports (basketball, soccer) or how you see things.


Treatment

  • Drug therapy: Drug therapy for blepharospasm has proved generally unpredictable and short-lasted. Finding an effective regimen for any patient usually requires patience of patient and physician.
  • Botulin toxin injections
  • Surgery: Those patients that have not responded well to medication or botulinum toxin injection are candidates for surgical therapy. The most effective surgical treatment has been protractor myectomy, the removal of muscles responsible for eyelid closure.
  • Dark glasses, for sunlight sensitivity as well as to cover one's eyes from other people.
  • Stress management and support groups can help sufferers deal with the disease and prevent social isolation.

Blepharospasm may vary from only a slightly annoying condition to a disabling disorder which interferes with daily activities such a reading, watching television, and driving, Up to two thirds of patients are rendered functionally blind by their blepharospasm.
In addition to the frequent coexistence of blepharospasm and dystonia in other body segments, the relatively frequent occurrence of family history of dystonia, essential-type tremor, or both supports the hypothesis that blepharospasm and other forms of dystonia may be genetically related.
This is probably due to a reduction in the tonic inhibition of the trigeminal reflex blink circuits as a result of a mild striatal dopamine depletion coupled with an adaptive increase in the drive on the trigeminal sensory-motor blink circuit in response to the facial nerve lesion.
