  Purpose

Non-24-hour sleep-wake disorder (N24HSWD) is a condition experienced primarily by totally blind individuals that results in abnormal night sleep patterns and chronic daytime sleepiness. This is a research protocol to develop a patient registry of subjects who may suffer from N24HSWD and who are totally blind with no light perception. Subjects participate in the study through a phone survey. This patient registry will be used to better understand sleep related problems in blind individuals, and identify subjects who are interested in participating in research and clinical studies related to N24HSWD. The survey consists of questions regarding the degree of vision impairment and sleep problems that the subjects may be experiencing.
