Question
What’s causing the redness in a facial paralysis patient’s eyes?
Answer
In addition to controlling the orbicularis muscle that closes the eyes, the facial nerve also controls a muscle responsible for opening the eyes. If a patient has a larger eye slit, making it difficult to close or blink their eyes, especially when exposed to air for an extended period during deep sleep, the conjunctiva can become dry. This can easily lead to an eye infection, which can be harmful to vision if severe. Treatment for facial neuritis requires a long time, and in addition to nerve treatment, it also requires long-term follow-up checks. Wishing the patient a speedy recovery!
