Development of a Patient Registry of Blind Subjects With Sleep-related Problems
Non-24-hour sleep-wake disorder (Non-24) 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 Non-24 and who are blind. Subjects participate in the study through a phone
survey. This registry will be used to better understand, sleep related problems in blind
individuals, including the investigation of a potential treatment, recruitment for future
clinical studies, and to provide a forum for raising awareness about Non-24. The survey
consists of questions regarding the degree of vision impairment and sleep problems that the
subjects may be experiencing.
