Performing horizontal upper eyelid tightening generally results in secondary improvement of ptosis associated with floppy eyelid syndrome, according to a study by researchers in New York and Minnesota.

David M. Mills, MD, and colleagues evaluated the change in upper eyelid position for 24 eyelids of 18 patients treated with horizontal surgical tightening involving full-thickness wedge resection.

Preoperative and postoperative upper eyelid positions were measured by the margin reflex distance, according to the study.

Preoperatively, margin reflex distance averaged 1.9 mm, ranging from -0.5 mm to 4 mm. After horizontal upper eyelid tightening, margin reflex distance averaged 3.2 mm, ranging from 0.5 mm to 6 mm.

The change in margin reflex distance averaged 1.3 mm, ranging from -0.5 mm to 2.5 mm (P < .001), according to the study, published in the October issue of Ophthalmology.
