  • Entropion

    Entropion is a medical condition in which the eyelid (usually the lower lid) folds inward. It is very uncomfortable, as the eyelashes constantly rub against the cornea and irritate it. Entropion is usually caused by genetic factors. This is different from when an extra fold of skin on the lower eyelid causes lashes to turn in towards the eye (epiblepharon). In epiblepharons, the eyelid margin itself is in the correct position, but the extra fold of skin causes the lashes to be misdirected. Entropion can also create secondary pain of the eye (leading to self trauma, scarring of the eyelid, or nerve damage). The upper or lower eyelid can be involved, and one or both eyes may be affected. When entropion occurs in both eyes, this is known as "bilateral entropion". Repeated cases of trachoma infection may cause scarring of the inner eyelid, which may cause entropion. In human cases, this condition is most common to people over 60 years of age. Lower lid entropion is a common condition in elderly individuals; the prevalence increases steadily with age. Entropion is an inversion of the eyelid (ie, inward turning of the eyelid margin) toward the globe. According to its anatomic features, the condition is classified as involutional, cicatricial, or congenital. Choice of surgical approach is directed by the underlying etiologic factor(s). Symptoms of entropion include: Redness and pain around the white part of your eye, Sensitivity to light and wind, Sagging skin around the eye, Epiphora, Decreased vision because of damaged cornea. Redness of the of your eye, Eye irritation or pain, Watery eyes (excessive tearing), Mucous discharge and eyelid crusting, Decreased vision. The other symptoms of entropion result from the friction of your eyelashes and outer eyelid against the surface of your eye. You may have signs and symptoms such as: The feeling that there's something in your eye.

  • Entropion

    Entropion (en-TROH-pe-on) is a condition in which your eyelid turns inward so that your eyelashes and skin rub against the eye surface, causing irritation and discomfort. When you have entropion, your eyelid may be turned in all the time or it may only turn inward when you blink forcibly or tightly squeeze your eyelids shut. Entropion occurs most often in older adults, and it generally affects only your lower eyelid. Artificial tears and lubricating ointments can help relieve symptoms of entropion, but you'll often need surgery to correct it. Left untreated, entropion can cause damage to the clear part of your eye (cornea), eye infections and vision loss. The prevalence of involutional entropion was 2.1%; 1.9% in men and 2.4% in women. The prevalence of involutional ectropion was 2.9%; 5.1% in men and 1.5% in women. Dry eye syndrome, lower retractor laxity, and superficial punctate keratopathy were seen significantly more often in patients with involutional entropion than in those with involutional ectropion (p < 0.001). Chronic conjunctivitis was significantly more common in patients with involutional ectropion than in those with involutional entropion (p < 0.001). The axial ocular globe projection was significantly smaller in patients with involutional entropion than in those with involutional ectropion (p < 0.001). The prevalence of involutional entropion and ectropion in the elderly population is 2.1% and 2.9%, respectively. The axial ocular globe position plays a pathogenic role in involutional lower eyelid malposition.

    The prevalence of ectropium population in the Central-Western region of São Paulo state is 0.68%. The ectropium eyelid affect mainly male, over 70 years relating sun light exposition and with normal visual acuity. Evaluation of 10,432 individuals, residents in 11 cities of the health regional located in the Central-Western region of the state of São Paulo. The results were submitted to statistical analysis to evaluate descriptive variables and the prevalence of ectropium eyelid. Seventy-one ectropium eyelid patients were detected, with an estimated prevalence of 0.68%. The prevalence was not similar in all the studied municipalities. Most ectropium people eyelids presented age over 70 years and are males. Cataract was concurrently present in 28.0% of them. Medical therapy may be warranted for patients who decline surgery and as a temporizing maneuver in patients who may improve spontaneously. Treatment is a relatively simple surgery in which excess skin of the outer lids is removed or tendons and muscles are shortened with one or two stitches. General anesthesia is sometimes used before local anesthetics are injected into the muscles around the eye. Prognosis is excellent if surgery is performed before the cornea is damaged. Ocular lubrication and tear preparations are helpful for protecting the ocular surface and also may break the cycle in patients with spastic entropion due to dry eye syndrome. Eyelid hygiene, antibiotics, and corticosteroids are useful for the treatment of blepharitis, which may cause spastic entropion. Small amounts of botulinum toxin (5 U) is quite effective for the treatment of spastic entropion by weakening the pretarsal orbicularis oculi muscle. Patients with cicatricial entropion secondary to ocular cicatricial pemphigoid may benefit from systemic chemotherapy, usually dapsone. The advanced treatment method used is surgery. Symptomatic therapy can be achieved using artificial tear ointment or drops. Moisture shields are also helpful. Additionally, the lower lid can be taped down slightly, everting the lid and lashes from the eye using specially designed or normal skin tape.
