For which of the following ocular conditions tucking of inferior lid retractors is done?
High-Yield Explanation
Senile ectropion: Involutional ectropion usually develops as a result of laxity of the suspensory system of the lower eyelid, and the medial and lateral canthal ligaments, allowing the lid to fall away from the globe. This laxity is accompanied by a horizontal lengthening of the lid. In the presence of a complete ectropion, the lower retractors or the capsulopalpebral tissues need to be reattached. Must know: Ectropion is an outward turning of the lid margin. It may be involutional, paralytic, cicatricial, mechanical or congenital. Involutional ectropion is the result of horizontal eyelid laxity from aging. Paralytic ectropion follows facial nerve palsy. Cicatricial ectropion is caused by contracture of the skin of the lid from trauma or inflammation. Mechanical ectropion usually occurs because of bulky tumors of the lid.
