Periocular spasms, which include myokymia, benign essential blepharospasm and hemifacial spasms, can often be difficult to diagnose because the signs and symptoms can be subtle. However, if the possibility of a periocular spasm is entertained, through thorough history gathering and a detailed examination, the diagnosis is readily reached. Patients with periocular spasms often complain of difficulty opening their eyes or keeping their eyes open.
Eye twitching, also known as eyelid twitching, is a very common eye condition. These annoying twitches usually affect only the lower eyelid of one eye, but the upper eyelid also can twitch. Most eye twitches don't affect you for long, but sometimes a twitching eye can last for weeks or even months.
Blepharospasm is abnormal contraction of the eyelid muscles. It often refers to benign essential blepharospasm BEB which is a bilateral condition and a form of focal dystonia leading to episodic closure of the eyelids. The exact cause of BEB is unknown and, by definition, it is not associated with another disease entity or syndrome. Symptoms usually begin as mild and infrequent spasms that progress over time to forceful and frequent contractures of the eyelids, in advanced cases causing functional blindness from inability to temporarily open the eyes.
Hemifacial spasm HFS is a rare neuromuscular disease characterized by irregular, involuntary muscle contractions spasms on one side hemi- of the face -facial. This disease takes two forms: typical and atypical. In typical form, the twitching usually starts in the lower eyelid in orbicularis oculi muscle.
Benign essential blepharospasm is a movement disorder dystonia of the muscles around the eye. No one knows exactly what causes it, but researchers believe it may be caused by a malfunction of certain cells in the nervous system called basal ganglia. Very rarely, eye twitching may be a sign of certain brain and nervous system disorders.

TAN, L. CHAN, E. Hemifacial spasm HFS is characterized by tonic and clonic contractions of the muscles innervated by the ipsilateral facial nerve. It is important to distinguish this from other causes of facial spasms, such as psychogenic facial spasm, facial tic, facial myokymia, blepharospasm, and tardive dyskinesia.
Hemifacial spasm HFS is a neurological disorder manifested by twitching on one side of the face due to involuntary contractions of the eyelid and other facial muscles. It usually begins gradually around one eye and may eventually spread the muscles around the mouth and neck on the same side. These muscle spasms are very brief but occur rapidly and repetitively.
Hemifacial spasm HFS is an involuntary twitching or contraction of the facial muscles on one side of the face. Medication, surgery, and Botox injections are treatment options to stop the spasms and relieve the discomfort. Each treatment offers benefits, but each has limitations. You and your doctor should determine which treatment is best.
