Doctor Doan Thi Phuong Nhi, from the High-Tech Eye Center at Tam Anh General Clinic District 7, explains that neuromuscular transmission disorders occur when nerve signals to the eyelid muscles are disrupted or transmitted abnormally, causing involuntary muscle twitching. Nguyen Van Giau experienced mild, intermittent eyelid twitching or strong spasms that temporarily closed her eye. Excessive blinking can lead to uneven tear film distribution on the cornea, causing dry eyes and temporary blurry vision. Prolonged twitching also increases friction between the eyelid and the eyeball surface, creating an irritating sensation, as if a foreign object is present.

While often not dangerous, the condition can be bothersome and affect daily activities.

Doctors prescribed botox (botulinum toxin) injections into the affected muscles. This substance relaxes muscles by inhibiting acetylcholine, a neurotransmitter, temporarily blocking nerve signals to the muscles and reducing spasms.

After a two-week follow-up, Nguyen Van Giau's eyelid twitching completely resolved, along with the irritation in her right eye. Her vision improved from 7/10 to 10/10. According to Doctor Nhi, botox has a temporary effect, with each injection typically lasting about 3-4 months, depending on the individual's response and the targeted muscle group.

Patients need regular follow-up appointments to monitor for recurrence. If symptoms like continuous eyelid twitching or periorbital spasms reappear, patients should visit an ophthalmology specialist for evaluation and repeat injections as advised.

Alongside treatment, patients should prioritize sufficient sleep, increase physical activity, consume magnesium-rich foods such as pumpkin and potatoes, and reduce stimulants like coffee and alcohol to limit nerve irritation.

Eyelid twitching is common, and its cause is often unknown. Fatigue, lack of sleep, stress, or high caffeine intake are common triggers. However, in some cases, it can indicate neurological conditions. Doctor Nhi advises patients to seek an eye examination if eyelid twitching is prolonged, severe enough to make opening the eye difficult, or accompanied by facial distortion, numbness, or one-sided facial spasms.
