Effectiveness of the Lower Eyelid Suspension Using Fascia Lata Graft for the Treatment of Lagophthalmos due to Facial Paralysis

Table 3

Statistical values of preoperative and postoperative Schirmer, TBUT, PA, MRD1, MRD2, and scleral show distances (TBUT: tear break-up time, PA: palpebral aperture, MRD1: margin reflex distance 1, MRD2: margin reflex distance 2, and scleral show distance: lower lid margin-limbus distance). (Med: Median, Min: minimum, Max: Maximum, Avg: Average, S.d: Satandart deviation).
