What is eyelid twitching?

Eyelid twitching is divided into two different conditions: spontaneous twitching and involuntary twitching, which are caused by different reasons. Autonomous twitching is mainly due to foreign body sensation, dryness, tingling and other reasons in the eyes, so patients keep blinking to try to relieve symptoms. The common inducing factors are keratitis, keratoconjunctival xerosis, trichiasis, corneal foreign body, conjunctival foreign body, allergic conjunctivitis, conjunctival stones, etc. Involuntary twitching refers to eye twitching that the patient cannot control consciously. Due to orbicularis oculi muscle, the main inducing factors are fatigue, anxiety, staying up late, tension, mental stress, insufficient sleep time, viral infection, cold, facial neuritis, microfocal cerebral infarction, demyelination, etc. These two eyelid twitching need to be examined in time in hospital ophthalmology to find out the cause of the induction, and then treat the primary disease.
