Some patients with facial palsy may have symptoms such as incomplete eyelid closure and frequent blinking during the course of the disease, which can lead to eye diseases such as dry conjunctiva and eye infections, which can also affect vision in severe cases. Facial neuritis takes a long time to treat, and ophthalmology treatment should not be neglected while treating facial palsy. A bi-weekly visit to an eye care professional is usually required. Patients themselves can also take some active protective measures. Specific methods are as follows: 1. Give local eye drops to the affected eye frequently, such as drops with Pearl Bright Eye Solution or Runshu, to keep the corneal surface moist and prevent infection. If there are signs of infection, antibiotic eye drops should be used. 2. Antibiotic eye ointment can be used at night before going to bed. Such as erythromycin eye ointment and other eye coating; exposed cornea has eye ointment and air isolation, can avoid drying and pollution. Special eye shields can also be used to reduce the evaporation of water from the corneal surface, while preventing infection.
