Method
- New technique paper: resection of the Müller muscle and conjunctiva.
- Patient selection test: the eyelid must lift to a cosmetically acceptable level after a drop of 10% phenylephrine hydrochloride in the eye.
- Only patients who pass this phenylephrine test have the surgery.
Findings
- Satisfactory results in 27 of 28 operated eyelids.
What it means for a patient
- This is the origin paper for Müller muscle-conjunctival resection (MMCR), still used today for mild to moderate ptosis.
- The phenylephrine test described here is still used to select candidates for this surgery over other ptosis techniques.
- The abstract does not give a measured eyelid height outcome or follow-up length, only "satisfactory" as the result category.

Terms
- Blepharoptosis: drooping of the upper eyelid.
- Müller muscle: a small smooth muscle in the upper eyelid that helps hold it open.
- Phenylephrine test: eye drops that stimulate Müller muscle to preview how much a ptosis surgery could lift the eyelid.
