Condition: Facial Nerve Palsy · Corneal Exposure · Paralytic Lagophthalmos · Sponsor: University of Alberta
The eyelids protect the cornea and eyelid closure is essential to ocular health and clear vision. Patients with permanent Bells palsy or facial nerve palsy from other reasons such as tumours or trauma may be unable to blink and protect their cornea. Irreversible visual loss can occur if the cornea is not kept lubricated. Current treatment options for patients whose eyelid blink does not recover include lubricating the eye every hour or two with drops and lubricating ointment at night, patching the eye closed, sewing parts of the eyelid together (tarsorrpahy), upper lid gold weight or a dental wire spring. It is inconvenient to lubricate the cornea constantly, and the lubricating drops and ointment usually cost more than $80.00 per month. Lubrication often blurs vision, because the patient must look through a film. Patching the eye closed and tarsorraphy deprives the patient of peripheral vision, can impede social interaction, and is objectionable cosmetically. Upper-lid gold weights can be placed underneath the eyelid skin and work by gravity. A gold weight will only work when the patient initiates a forced blink. Gold weights may not work when the patient is lying down because there is no gravity to assist lid closure. The eyelid skin is the thinnest skin in the body and can extrude through the skin over time. Eyelid springs made of metal dental wire exist but are not frequently used because they often extrude through the thin eyelid skin. Also, dental wire springs re…
