Abstract

Progressive degeneration of elastic and fibrous tissues within the lid is the underlying etiology of Involutional ectropion. Our case is a tarsal ectropion. The probable etiology is disinsertion of lower eyelid retractors. Lateral canthotomy and inferior cantholysis is performed. 15 no blade is used to put an incision at greyline to divide anterior lamella & posterior lamella. Dissection is done to separate anterior lamella from posterior. Strip of anterior lamella is excised. Posterior lamella containing tarsus is cut from below. Conjunctiva is scraped off from this strip using 15 no blade. Mucocutaneous strip is excised to denude tarsus. 4-0 prolene suture is passed to anchor it to periosteum behind lateral orbital rim. A new lateral canthal angle is formed with 8-0 vicryl suture. Orbicularis oculi is approximated using 6-0 vicryl. Skin is closed with 6-0 prolene suture. Lateral tarsal strip is a simple procedure to rectify lateral canthal tendon laxity and malposition of eyelid.
