What may indicate a need for a lateral tarsal strip procedure?

A lateral tarsal strip procedure is primarily indicated when there is significant corneal exposure due to conditions like ectropion, where the eyelid turns outward and fails to cover the eye properly. This exposure can lead to dry eyes, irritation, and potential damage to the cornea, necessitating surgical intervention to restore eyelid function and protect the corneal surface.

In cases of ectropion, simply addressing the excess skin or other related issues won't effectively resolve the underlying problem of eyelid malposition. The tarsal strip procedure focuses on reestablishing the proper tension and positioning of the eyelid, ensuring it can adequately cover and protect the eye, thus preventing complications associated with prolonged exposure of the cornea.

Other options relate to different ocular conditions, such as cosmetic concerns or dryness, which do not align with the specific purpose of a lateral tarsal strip procedure. Therefore, recognizing the role of eyelid position and its implications for corneal health is key to understanding why significant corneal exposure from ectropion is the indication for this surgical approach.
