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.

Condition or disease Intervention/treatment Phase
Blindness Biological: Melatonin Not Applicable

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.

Drug Information available for: Melatonin

Arm Intervention/treatment
Experimental: Melatonin
Subjects may opt to enroll in this treatment sub-study involving melatonin treatment (0.1 - 3 mg, daily) for up to 1 year, with a minimum of 6 weeks. Throughout treatment, subjects will continue their saliva, plasma, and/or urine sampling to test for treatment efficacy.
Biological: Melatonin
0.1-3 mg, daily, up to 1 year (minimum duration of 6 weeks)




Primary Outcome Measures :
  1. Circadian Phase Marker, as Measured by the Melatonin Levels in Salivary, Plasma and/or Urine Serial Sampling. [ Time Frame: every 2-4 weeks throughout the entire study ]

Secondary Outcome Measures :
  1. Polysomnography (Sleep Assessment) [ Time Frame: 1 12-hour assessment any time during the study ]
