Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Dry eye syndrome is a benign situation however its impact on patient's quality of live and on health system is not trivial. One problem is the lack of correlation between patient's symptoms and physical sign observed on slit lamp examination. Eye blinking is a parameter of increased interest in this pathology particularly its frequency. To date no treatment of dry eye syndrome has a proven impact on eye blinking frequency. However recording of blinks has mostly been performed on short duration (3 to 5 minutes) and the distribution of intervals between 2 blinks is not gaussian but exponential. In this study, it is proposed to use modern eye-movement recorder to measure the blink frequency on longer duration (12 minutes) while reading on a screen computer and during a face-to-face interview before and after treatment of meibomian gland dysfunction responsible of moderate to severe dry eye syndrome.
