Entropion / Ectropion


Entropion is a malposition of the eyelid, which is directed towards the globe. This makes eyelashes brush against the cornea producing a foreign body feeling. This may generate ulcers and infections causing great pain to the patient.

The most common type of entropion is the Involutional one, which is caused by the laxity of the eyelid’s tendons. It is usually quite irritating for the patient, and it requires surgery. It is performed under local anesthesia and the success rate is higher than 95%, returning the normal function of the eyelid.


The ectropion is, like the entropion, a palpebral edge disease. The most frequent cause of it is the Involutional one (due to age), where there is a hyperelasticity of the periocular tissues. Among other reasons, there is the facial paralysis. In the ectropion, the eyelid turns outwards and stops being in contact with the globe, what makes the closing of the eye difficult. In the long run, it may bring about severe consequences due to exposition, such as irritation, keratitis and chronic ulcers.

In such case, a surgery is performed in order to restore the original palpebral position. The technique used to perform this surgery is the lateral tarsal strip, in which the lid is stretched and anchored to its lateral angle. It is performed under local anesthesia and it lasts about 30 min.
