A New Surgical Method for Medial Ectropion Repair: Fixing the Lower Eyelid Retractor to the Back of the Tarsal Plate.

Involutional ectropion is a disease in which the eyelids are everted outwards, and because the eyelids move away from the eyeballs, the ocular surface and conjunctiva are exposed causing inflammation, pain, photophobia, foreign body sensation, epiphora, and blurred vision. It is thought to be caused by horizontal and vertical laxity. Various surgical methods have reportedly been used to correct involutional ectropion. Shortening the lower eyelid retractor (LER) is an indispensable surgical operation for medial ectropion. When the LER is shortened, it is usually fixed to the lower edge of the tarsal plate. Herein we describe a new type of surgery that has now been performed on 6 eyes in 4 patients. The procedure involves separating the conjunctiva from the tarsal plate, inserting the LER between the conjunctiva and the tarsal plate, and then fixing it to the back of the tarsal plate. In all 6 eyes, the lower eyelid now contacts the eyeball, and morphological improvements were achieved. This new surgical method is a useful way to raise the tarsal plate.
