Causes of Entropion
Entropion is the inward turning of the eyelid, usually the lower.
Laxity of the eyelid tendons with weakening of the eyelid muscles associated with age commonly cause entropion, although it can also occur as a result of trauma or scarring. This can cause the lashes to rub against the cornea.
Patients may experience eye pain, excessive tearing, redness, and irritation.
Left untreated, entropion can lead to permanent damage to the cornea leading to vision loss.
Causes of Ectropion
Ectropion is an outwardly turned or sagging lower eyelid. Laxity of the eyelid tendons also commonly cause ectropion. Other causes include trauma, scarring, and facial nerve paralysis associated with Bell’s palsy. This causes exposure of the ocular surface causing dryness and excessive tearing.
Lubrication drops or ointments may give temporary relief of irritation from both entropion and ectropion. Surgical treatment is indicated when conservative treatment fails. Surgery involves tightening the tendons in order to reposition the lower eyelid to its normal anatomic position.
Entropion and ectropion repair is normally performed on an outpatient basis under a local anesthesia with sedation, or “twilight”. This is performed by an anesthesiologist with the benefit of greater comfort and fast recovery.
You will go home the same day as the procedure. There is minimal pain after the procedure, although some discomfort is expected. Temporary blurred vision is normal. Ice packs are recommended the first 24 hours. Bending and heavy lifting should be minimized. Swelling and bruising around the eyes lasts for one to two weeks. You will be asked to stop aspirin and other blood thinners prior to surgery to minimize bruising and prevent excess bleeding during the operation. Most patients can return to work after one week. Eyelid tissue tends to heal very well with little scarring. Since the incision is made in the crease of the eyelid, any residual scar is naturally hidden.
