Lower eyelid excursion: A functional and cosmetically relevant parameter in the treatment of lower eyelid retraction

The purpose of this study was to assess and quantify lower lid excursion following repair of lower lid retraction.In this retrospective cohort study, a case review of patients who had undergone ear-cartilage grafting for lower lid retraction was undertaken. Surgical correction involved the placement of autologous cartilage between the tarsal plate and lower lid retractors. Measurements taken pre- and post-operatively were the marginal reflex 2 (MRD2) and the lower scleral show (LSS). The lower lid excursion on downgaze (LLE) was measured only post-operatively with a comparison made between operated eyes and control eyes.
