Brief summary

This is a prospective, single-center study in normal subjects aged 20 to 89 years. The objective was to describe upper eyelid laxity by age group (20/29 years old, 30/39 years old, 40/49 years old, 50/59 years old, 60/69 years old, 70/79 years old and 80/89 years old) measured with the method of McNab and studying it according to her customary side of sleep. In addition, we evaluated a method for measuring tarsal laxity.

Measurement using a soft slider of the distance between our 2 marks The difference obtained between the measurement and the initial 10 millimeters corresponds to the tarsal laxity.
