Although both facial spasms and blepharospasms develop in the face, there are some differences in location. Blepharospasm occurs in middle-aged and older women, often with bilateral lesions, progressive, 2/3 female, and most stable within 3-5 years, manifesting as frequent and involuntary transients, tight frowning of the eyes, spastic or tonic lid closure of both eyes, and secondary lesions such as brow ptosis, ptosis, and eyelid skin laxity due to prolonged and intense spasm of the orbicularis oculi. These patients often have good vision, but are unable to use it well because their eyes are always involuntarily closed. And these patients often cannot open their eyes the more they want to use them, while they can open them well when they are mentally relaxed without using them. Facial muscle spasm, also known as hemifacial spasm, is an involuntary spasmodic twitch of one side of the face muscle. In some patients, the spasm of the eyelid on one side gradually extends to the corner of the mouth and the entire half of the face on the same side, and facial movements such as talking and eating can trigger or aggravate the spasm, and often the spasm cannot be controlled with consciousness, and the more nervous the patient is, the easier the seizure is, so it is very painful. There are many patients who cannot distinguish between blepharospasm and facial spasm, just like the patient above. The most direct difference between the two is that the former manifests bilaterally in the eyes, while the latter manifests unilaterally in the eyes and face, but also bilaterally but very rarely.
