Müller's Muscle–Conjunctival Resection for Correction of Upper Eyelid Ptosis

Abstract

Müller's muscle-conjunctival resection is effective for ptosis correction in patients with good levator muscle function; good eyelid symmetry is achieved in most patients. Phenylephrine testing underestimated the ptosis correction achieved with MMCR by 40%. The relationship between MMCR and ptosis correction is complex.
