Inability to fully close one or both eyelids, which may leave part of the eye exposed.
To support a rating for lagophthalmos, medical records and eye examination findings are the most direct evidence. An ophthalmologist or other eye care provider documenting that you cannot fully close your eyelid — in one eye or both — directly ties to the criteria. Findings that specify which eye or eyes are affected are especially relevant, since that is what separates the 10% rating from the 20% rating. Records showing the condition is present in both eyes at the same time would support the bilateral rating. Statements from you or people who know you describing what you experience — such as eye dryness, irritation, or trouble sleeping because your eye stays open — can help show the condition is ongoing in the affected eye or eyes.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
