Entropion is caused by weakness of the lower lid retractor muscle, loss of contraction of the orbital septum and lower lid skin to hold the lid orbicularis muscle, and lack of adequate support behind the eyelid in older adults with reduced orbital fat. Scarring lid entropion can occur in both upper and lower lids. It is caused by scarring contraction of the lid conjunctiva and lid plate. Symptoms: 1. Tear overflow occurs due to ectropion of the tear dots. The conjunctiva of the exposed portion becomes congested, hypertrophic, dry, rough, and even epidermis-like. 3. Severe cases may lead to incomplete lid closure and exposure keratitis. Treatment: 1. scarring: complete excision of the scar and skin grafting. 2, paralytic: in mild cases, apply eye ointment and eye pad dressing, in severe cases, eyelid suturing should be performed to protect the cornea. 3. Geriatric: In mild cases, the lid should be instructed to wipe tears upward to reduce or prevent exophthalmos from increasing. In severe cases, surgical correction is based on the principle of shortening the lid margin. The easiest method is to make a triangular excision in each of the conjunctival lid layer and skin muscle layer and then suture it. Disease Description: Ectropion is a condition in which the lid margin is turned outward away from the eye and the conjunctiva is often exposed to varying degrees, often in combination with incomplete lid closure. Symptoms and signs: 1. Mild: Only the lid margin leaves the eye, but tear spillage results from disruption of the capillary action between the eyelid and the eye. 2. Severe: the lid margin is ectropion and part or all of the lid conjunctiva is exposed, causing the lid conjunctiva to lose tear wetting, initially localized congestion and increased secretions, and over time dryness and roughness, highly hypertrophic, and presenting horn words. Lower lid ectropion can cause the tear dots to leave the tear lake and cause tear overflow. In more studies, lid ectropion often has incomplete eyelid closure, causing the cornea to lose protection and the corneal epithelium to dry out and fall off, easily causing exposure keratitis or ulcers.
