What causes the lower eyelid of the left eye to throb?

The throbbing of the lower eyelid of the patient’s left eye is mostly caused by the dysfunction of the eyelid muscle and orbicularis oculi muscle, and the possible causes include mental tension, eye fatigue, facial neuritis, facial nerve compression, conjunctivitis, and inverted eyelashes.
1. Physiological factors: Excessive eye use, cold face, mental stress and other physiological factors may cause fatigue of eyelid muscles and orbicularis oculi muscles, which may lead to fluttering of the lower eyelids of the patient’s eyes.
2. Neuropathy: Tumor, blood vessels and other tissues compressing the facial nerve or facial neuritis caused by viral infection of the facial nerve can make the nerve abnormally excited, which can cause the patient’s eyelid jumping.
3. Others: Conjunctivitis, inverted eyelashes and other stimulation of the eye surface tissues may also lead to eyelid fluttering, and some patients with eyelid fluttering have unclear etiology, and even after a variety of tests, they still can not find the cause of the disease.
It is recommended that patients with severe fluttering eyelids should consult a doctor in a timely manner to identify the cause and follow the doctor’s instructions for treatment.
