If unable to receive surgery, patients should be administered artificial tears at least four times per day to the cornea to preserve the tear film. Treatment of lagophthalmos can include both supportive care methods as well as surgical options. This can make the patient look younger, but if too much skin is removed, the appearance is unnatural and lagophthalmos may occur. Today, lagophthalmos may arise after an upper blepharoplasty, which is an operation performed to remove excessive skin overlying the upper eyelid (suprapalpebral hooding) that often occurs with aging. It can also occur in patients with Grave’s Ophthalmology. Lagopthalmos can also occur in comatose patients having a decrease in orbicularis tone, in patients having palsy of the facial nerve (seventh cranial nerve), in people with severe exophthalmos and in people with severe skin disorders such as ichthyosis. Lagophthalmos can arise from a malfunction of the facial nerve. Public awareness of the condition is not widespread in one instance, a passenger was removed from a US Airways flight because of it. Eye drops may also be used to provide additional lubrication or to stimulate the eyes to increase tear production. Punctal plugs may be used to increase the amount of lubrication on the surface of the eyeball by blocking some of the tear-drainage ducts. Treatment may involve surgery to correct the malposition of the eyelid(s). It is often caused by an anomaly of the eyelid that prevents full closure. The degree of lagophthalmos can be minor (obscure lagophthalmos) or quite obvious. It may reduce the quality of sleep, cause exposure-related symptoms or, if severe, cause corneal damage ( exposure keratopathy). Nocturnal lagophthalmos is the inability to close the eyelids during sleep. Lagopthalmos leads to corneal drying and ulceration. If this process is impaired, as in lagophthalmos, the eye can suffer abrasions and infections. This is crucial to maintain lubrication and proper eye health. The tears also flush out foreign bodies and wash them away. īlinking covers the eye with a thin layer of tear fluid, thereby promoting a moist environment necessary for the cells of the exterior part of the eye. Lagophthalmos is the inability to close the eyelids completely.
