Secondary blepharospasm occurs due to some identifiable cause. The most-common cause of secondary blepharospasm is a reaction to antipsychotic medications, and is called tardive dystonia.
The medical term for this phenomenom is blepharospasm, and it is any abnormal tic or twitch of the eyelid. It normally refers to benign essential blepharospasm, a neurological movement disorder involving involuntary and sustained muscle contractions of the muscles around the eyes. Benign means the condition is not life threatening. The cause is unknown, but fatigue, stress, or an irritant are possible contributing factors. Some drugs can induce blepharospasm, such as those used to treat Parkinson's disease, as well as sensitivity to hormone treatments, including Estrogen replacement therapy for women going through Menopause. Blepharospasm can also be a symptom of acute withdrawal from benzodiazepine dependence. In addition to blepharospasm being a benzodiazepine withdrawal symptom, prolonged use of benzodiazepines can induce blepharospasm and is a known risk factor for the development of blepharospasm.
The prognosis of secondary polycythemia depends on the underlying cause. If the cause is identified and treated promptly, the prognosis is generally favorable. However, if left untreated, secondary polycythemia can lead to complications such as blood clots, strokes, or heart problems, which can affect long-term outcomes. Regular monitoring and management of the underlying condition are key to improving prognosis.
Essential hypertension is high blood pressure without a clear underlying cause, while secondary hypertension is high blood pressure that is due to a specific medical condition, such as kidney disease or hormonal disorders. Essential hypertension is more common and typically develops gradually over time, whereas secondary hypertension can develop suddenly and may require treatment of the underlying cause.
The biotic components of a community can cause both primary and secondary succession. Primary succession occurs on bare rock or newly formed land, while secondary succession occurs in areas that were previously inhabited but then disturbed. Both types of succession involve the gradual replacement of species over time in response to environmental changes.
Some of the causes of primary amenorrhea can also cause secondary amenorrhea.The most common cause of seconardy amenorrhea is pregnancy.The cessation of menstruation also occurs permanently after menopause or a hysterectomy.
The cause of benign essential blepharospasm is unknown. Blepharospasm is not caused by a problem with the eyes themselves, but rather with the brain regions controlling the muscles of the eyelids.
Blepharospasm is an involuntary closure of the eyelids.
The medical term for involuntary contractions of the eyelid is blepharospasm. This condition can cause the eyelid to twitch or close intermittently and may be temporary or chronic.
Pneumonia can cause Secondary vasculitis
Sarcoidosis can cause Secondary vasculitis
Blepharospasm has a number of symptoms. These include sensitivity to bright lights, escessive blinking and spasming of the eyes, dryness of the eyes, and uncontrollable twitching of the eyes and facial muscles.
Autoimmune diseases can cause Secondary vasculitis
Hepatitis B can cause Secondary vasculitis
Hepatitis C can cause Secondary vasculitis

Blepharospasm often begins with increased frequency of blinking, which may be accompanied by a feeling of irritation in the eyes or "dry eye." It progresses to intermittent, and then sustained, forceful closure of the eyelids.
Allergic reactions to antibiotics can cause Secondary vasculitis
