Lagophthalmos is a condition in which the eyelids do not close together to completely cover the globe of the eye. This inadequate closure of the lids often causes the front surface of the eye to be improperly or inadequately lubricated. As a result, the front surface of the eye dries and generally is uncomfortable.
A second type of lagophthalmos is called nocturnal lagophthalmos, in which the eyelids do not completely close and cover the globe of the eye while sleeping. This causes discomfort, especially in the early morning.
All types of lagophthalmos commonly cause a sandy, gritty feeling accompanied by increased watering (tearing) of the eyes. Treatment may include artificial tears, lubricating ointment and occasionally taping the eyelid or patching at bedtime. If medical therapy fails, surgical procedures may be beneficial.
