The Effect of Supine Versus Upright Positioning on Eyelid Height in the Nonsurgical Patient.

Purpose: To directly compare margin-reflex distance 1, margin-reflex distance 2, and palpebral fissure in the upright versus supine positions in nonsurgical patients.

Methods: A total of 43 patients (31 female, 12 male, and age range 26-96) were enrolled. Photos were taken in the clinic in the upright and supine position with a ruler placed vertically in the same plane as the eyelid, and the above computer-analyzed measurements were obtained.
