Chronic sleep restriction induces oculomotor impairment with inadequate compensation.

ABSTRACT:

Study objectives

Chronic sleep loss is widespread and can cause deficits in vigilant attention. There are few practical biomarkers that can be used to assess the impact of chronic sleep loss on alertness and performance. Those that are available, such as tests of vigilant attention, cannot discriminate chronic sleep loss from other impairments, like alcohol intoxication, limiting the use of such tools. We aimed to test whether a suite of behavioral oculometrics would be sensitive, and perhaps specific, to chronic sleep restriction (CSR).

Methods

We conducted a randomized, counterbalanced, cross-over study to compare behavioral oculometrics following a week of 5 h of time in bed versus 9 h of time in bed. Each experimental week was preceded by a washout week of 9 h nightly ti
