For the eye to function effectively as a protective barrier and ensure proper lubrication, the eyelid must maintain precise positioning and movement across the eye’s surface. This intricate coordination relies on a mechanical system of muscles and ligaments, which, over time and with factors like injuries or previous surgeries, can experience wear and malpositioning.
How does ectropion present?
Ectropion, characterised by an outward-turning eyelid, presents with tearing eyes and, in advanced cases, may lead to redness and irritation along the lower lid’s lining. Severe ectropion of the lower eyelid can result in pain and potentially jeopardise eyesight due to excessive dryness.
How does entropion present?
Entropion, on the other hand, involves an inward turn of the eyelid’s edge, causing the coarse eyelashes and meibomian glands to make contact with the eye’s surface. This condition presents with pain, watering, a red eye, and an increased risk of infections and vision loss. Symptoms may develop gradually over weeks or months.
