Lagophthalmos is defined as the inability to close the eyelids completely. Blinking 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.

Blinking 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.
The tears also flush out foreign bodies and wash them away. This is crucial to maintain lubrication and proper eye health. If this process is impaired, as in lagophthalmos, the eye can suffer abrasions and infections. Lagopthalmos leads to corneal drying and ulceration.
Lagophthalmos can arise from
Malfunction of the
Facial nerve
Comatose patients having a decrease in orbicularis tone
Palsy of the facial nerve (7th cranial nerve)
Ichthyosis (a severe skin disorders)
