Young Blind Child Melatonin Treatment Study

Not Applicable
Terminated
Conditions
Blindness
Interventions
Biological: Melatonin
Registration Number
NCT00688935
Lead Sponsor
Oregon Health and Science University
Brief Summary

The primary goal of this study is to identify the presence of desynchronized circadian rhythms in 25 children by measuring melatonin secretion in serial blood or saliva samples, and to rule out any primary sleep disorders.

Detailed Description

Subjects will complete 25-hours of hourly salivary, plasma sampling biweekly. Melatonin will be measured in urine, for children under the age of 3. Sleep and behavioral questionnaires will be completed by parents and/or teachers. This study involves an optional, 1-year melatonin treatment sub-study, in which the children will take 0.1 - 3mg daily. A second optional sub-study involves a study of the child's sleep through polysomnography, in order to identify possible sleep disorders.
