Tuberous sclerosis complex

Question Question

Can tuberous sclerosis affect blinking and eye closure? If not, what could cause this?

Answer Answer

Lagophthalmos is the medical term for "incomplete closure of the eyelid." Lagophthalmos can cause drying, infection, corneal ulceration, corneal perforation, and loss of vision.^[1]

Lagophthalmos is often caused by facial palsy.^[2] Facial palsy may be due to a variety of conditions and factors, including Bell's palsy, trauma, infection, or tumors. Lagophthalmos can occur as a result of bulging eyes (e.g., as in Graves disease), or in individuals whose face has suffered scarring. Other causes, include ocular cicatrical pemphigoid, erythema multiforme, leprosy, chronic alcoholism, dementia, parkinsonism, general anesthesia, and coma. Temporary lagophthalmos can occur in infants or in people during sleep.^[1]^[3]^[2]

Treatment may include artificial tears, eye ointment, moisture chambers, or surgery.^[1]

It is possible that a tuberous sclerosis related tumor or complication could cause lagophthalmos. If you or a loved one has tuberous sclerosis and is experiencing lagophthalmos we strongly recommend that you speak with a geneticist or other healthcare professional who can help you determine the underlying cause of the condition.
