Different types of Eyelid Disorders
Dermatochalasis
Dermatochalasis is a condition, usually in the upper lid, that causes relaxed eyelid skin and muscle. Usually common in those older than 50, gravity, loss of skin elasticity and weakened connective tissues are the usual cause of dermatochalasis, though genetics is also a factor.
Dermatochalasis symptoms include fullness in upper lids, bags in the lower lids and lower lid wrinkles. Dermatochalasis can also obstruct vision. Eyelid surgery can help dermatochalasis by removing excess skin and sometimes underlying muscle as well.
Ptosis
Ptosis, or eyelid drooping, is excessive sagging of the upper eyelid. Ptosis is caused by weakened muscles that raise the eyelid, nerve damage to the eyelid muscle or loose upper eyelid skin. Ptosis can be present at birth, caused by aging or be the result of an injury or, very rarely a disease.
Eyelid lift surgery can be performed to correct sagging, drooping eyelids.
Entropion
Entropion, usually on the lower eyelid, is the term given when the edge of the eyelid is turned in and causes the lashes to rub against the eye.
Entropion can be present at birth or it can occur in older people who have weakened muscles in the lower part of the eye. Entropion risk factors include aging, chemical burns or trachoma infection. Your ophthalmologist can easily diagnose; artificial tears may help irritation or redness, but only surgery can correct the eyelid’s position. Entropion, untreated, can cause damage to your cornea, eye infections and vision loss.
Ectropion
Ectropion, usually on the lower eyelid, is when the eyelid is turned out and the inner surface is exposed. Ectropion is usually caused by aging but it can also be from a birth defect, such as Down Syndrome or scar tissue from burns. Ectropion symptoms include turned down eyelids, dry, red and painful eyes, excess tearing and chronic conjunctivitis. Ectropion can be relieved with artificial tears but may required surgery to tighten the muscles that hold the eyelid in place.
