Upper eyelid weighting for lagophthalmos results in contralateral upper eyelid elevation

Upper eyelid weighting decreases lagophthalmos by improving blink dynamics. The effect of weighting on static eyelid position is less well understood. This study describes the effect of upper eyelid weighting on ipsilateral and contralateral upper eyelid position. Patients with unilateral lagophthal...

Description
Summary:Upper eyelid weighting decreases lagophthalmos by improving blink dynamics. The effect of weighting on static eyelid position is less well understood. This study describes the effect of upper eyelid weighting on ipsilateral and contralateral upper eyelid position. Patients with unilateral lagophthalmos who underwent upper eyelid weight implantation were included. Primary outcome measures were ipsilateral and contralateral margin to reflex distance 1 (MRD1), preoperatively and postoperatively. MRD1 symmetry was assessed as a secondary outcome measure. Weight mass was examined as a covariate of MRD1 change. 23 patients (16 female, 7 male) met inclusion criteria. After weighting, contralateral MRD1 increased from mean [SD] 2.91 [1.41] mm to 3.77 [1.75] mm (p
