Primary outcome measures included lagophthalmos on blink, gentle and forced eyelid closure, upper eyelid margin to reflex distance (MRD1), corneal staining, static and dynamic validated scoring for facial palsy patients and complications.
Intraoperative lagophthalmos in patients with satisfactory surgical outcome correlated negatively with both preoperative MRD1 and levator function and accounting for both variables resulted in a stronger correlation than either variable alone.
The patients were treated with subconjunctival triamcinolone acetonide injections monthly and evaluated pre- and post-treatment by taking measurements of the upper margin reflex distance (MRD1, the distance between the upper-lid margin and the pupil center), lid aperture, lagophthalmos and proptosis.
