简要总结

Sleep disturbances are common among patients with liver cirrhosis, but the reasons are not well understood. In this project the investigators evaluated whether an increase in blood ammonia in patients with cirrhosis had an impact on sleep quality and the function of retinal ganglion cells measured by pupillary response to blue light.
