Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Case-control studies and meta-analysis have reported that several ocular features, especially the thickness of the peripapillary retinal nerve fiber layer and visual acuity, are related to the brain degeneration and cognitive impairment. In our study, we aim to quantitatively assess ocular features using structural and functional indicators and define its associations with brain development and intelligence in children.
