ectropion

An out-turning of an eyelid, usually the lower, so that the wet, inner, conjunctival surface is exposed to view. Ectropion is commonest in the elderly, in whom weak and lax eyelid muscles allow the lower lid to fall away from the eye. It can also be caused by paralysis of the flat muscle surrounding the eye, as in BELL'S PALSY or by scarring and shortening (contracture) of the lid skin (cicatricial ectropion).

Ectropion

A complication of blepharoplasty, in which the lower lid is pulled downward, exposing the surface below.

ectropion

Outward turning of the eyelid margin. The most common cause is a loss of tonus of the pretarsal orbicularis muscle combined with laxity of the medial and lateral canthal tendons, which occurs in old people and affects only the lower eyelid (involutional ectropion). Tears collect in the lacrimal lake and overflow onto the skin of the face. Other causes of ectropion are scarring, burns, trauma (called cicatricial ectropion), spasm of the orbicularis muscle, which may affect either the upper or lower eyelid, or paralysis of the orbicularis muscle in which only the lower eyelid is affected. Ectropion may lead to exposure keratitis as the lower part of the cornea remains exposed. Management includes instilling an ocular lubricant and patching the eye during sleep as a temporary measure, but, if severe, the treatment is surgical.

congenital ectropion A rare congenital eversion of the eyelid (most often the lower). It may be due to a deficiency of the anterior eyelid lamina. It is usually associated with other disorders, such as blepharophimosis syndrome or Down's syndrome.
ectropion uveae A turning of a portion of the posterior pigment epithelium of the iris growing or being drawn around the pupillary margin onto the anterior iris surface. It may be acquired (e.g. following iris neovascularization, neovascular glaucoma, iris melanoma) or congenital (e.g. neurofibromatosis).

On his physical examination, armorlike hyperkeratinized areas and fine deep fissures were observed over the whole body surface together with severe eclabium and ectropion. It was observed that fine fissures have been accompanied by bleeding, the hair was invisible because of massive keratin, the ears were underdeveloped (rudimentary), and eyelids and lips had mucous structure.
There was associated ectropion of both the eyes, eclabium of both the lips (Figure 2).
