Which condition might develop due to poor eyelid closure from ectropion?

Poor eyelid closure from ectropion can lead to multiple ocular complications, primarily because the eyelids play a crucial role in protecting the eye and maintaining moisture. One of the primary risks is corneal ulceration. When the eyelids are unable to close completely, the cornea may become exposed to environmental irritants, dust, and pathogens, resulting in scratching or abrasion of the corneal surface, which can progress to ulceration.

Additionally, ectropion can contribute to conjunctivitis. This occurs due to the lack of proper eyelid function leading to inadequate tear distribution and retention across the conjunctiva, making it more vulnerable to infection and inflammation. The exposure can also alter the normal tear film, aggravating irritation and promoting conjunctival inflammation.

Therefore, the combination of these two potential issues from ectropion—corneal ulceration and conjunctivitis—supports the choice that both conditions may develop as a consequence of inadequate eyelid closure.
