What condition involves the outward rolling of the eyelids?

The condition that involves the outward rolling of the eyelids is ectropion. This condition occurs when the eyelid margins turn away from the eye, exposing the inner lining of the eyelids and increasing the risk of irritation, dryness, and potential damage to the cornea. Ectropion can be caused by aging, as the structures of the eyelids lose elasticity, or it may result from injury, inflammation, or other underlying medical conditions. The outward position of the eyelid can also lead to excessive tearing, as tears may not properly drain through the puncta, further complicating the eye's health. Understanding ectropion is important in veterinary ophthalmology, as proper diagnosis and treatment can help prevent further complications for animals affected by this condition.
