The literature describes sleep fragmentation, circadian rhythm disruptions and reduced sleep efficiency. These manifestations are believed to be closely linked to both structural and functional abnormalities associated with SOD, potentially disrupting the natural circadian rhythm. Both anomalies in midline brain structures and decreased visual input could potentially impact melatonin secretion, although a distinct melatonin profile for SOD patients has yet to be identified. Furthermore, the specific contribution of these factors to sleep disturbances in SOD remains unexplored. The aim of this study is to evaluate the quality of sleep and its characteristics, along with the melatonin profile, among paediatric patients diagnosed with SOD. A comparison will be made between these findings and those of children with isolated bilateral visual impairment, as well as patients with agenesis of the corpus callosum.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>Participants aged between 3 and 18 years previously diagnosed with SOD will be recruited prospectively.

Additionally, plasma and salivary melatonin profiles will be assessed for each participant.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>This study has been approved by local Ethics Committee (N\u00b00049187\/23).
