Eye Sight Complications: Blepharospasm
Blepharospasm is a neurological disorder that causes involuntary muscle spasms, also called dystonia, of the eyelid. It is often called “benign essential blepharospasm.” This means that the cause of the condition is unknown and it is not life threatening. Blepharospasm is progressive, meaning that the illness gets worse as time goes on. People who have this condition suffer from impaired vision because the spasms force their eyelids to shut.
Benign essential blepharospasm usually begins with excessive blinking or irritation of the eye. Dry eyes are a common symptom, and doctors have debated as to whether or not dry eyes actually cause this disorder or are simply a symptom. When blepharospasm first appears, it may not occur often. In the initial phase of blepharospasm bright lights and fatigue can trigger a muscles spasm. As the disease progresses, the spasms become more frequent. Normally blepharospasm occurs during the day while the sufferer is awake. Sometimes a goodnights sleep can also stave off attacks for a few hours after waking. Eventually, blepharospasm attacks can last as long as two hours.
Although the actual cause of blepharospasm is currently unknown, there are a few theories. The symptoms of blepharospasm are caused by the basal ganglia, structures located at the base of the brain. They are responsible for controlling coordinated movement and in the cause of blepharospasm, do not function normally. The medical community is unsure what exactly goes wrong with the ganglia, but some have theorized that blepharospasm is caused by malfunctioning messenger chemicals, which carry information between cells. Blepharospasm usually develops spontaneously, so prevention is not possible. It may be genetic and may occur with other types of dystonia. Drugs that treat Parkinson’s disease can cause blepharospasm, but in that case the spasms stop if the patient stops taking the medication.
There is currently no cure for benign essential blepharospasm. However, treatment with Botox is available for some patients. There are also surgical options available that actually remove muscles from the eye area. However, most doctors consider surgery a last resort in blepharospasm treatment. These links are comprised of foundations dedicated to blepharospasm research and support, blepharospasm information, and information about clinical trials for blepharospasm.
Founded in 1976, this organization is dedicated the research of dystonia, which includes conditions such as blepharospasm. The Dystonia Medical Research Foundation facilitates volunteer work, funds research, and provides support for people with dystonia and their families. Their website contains information about dystonia as well as the foundation itself.
This UK based organization was established in 1983 by a small group of patients with dystonia. Their mission is to provide support and information for dystonia sufferers. They also provide funding for research. Their website provides services for patients as well as information for healthcare professionals.

Eye care can be expensive, so the National Eye Institute has provided a list of organizations that can help individuals pay for their care. The list includes organizations that help pay for eye exams and surgery, eyeglasses, prescription drugs, and government programs.
