Short-term exposure to full-spectrum light induces distinct, refraction-dependent ocular structural responses in children with IXT. While emmetropic eyes maintain normal circadian growth patterns, myopic eyes exhibit acute axial shortening. The dissociation between axial shortening and choroidal thickening in myopic eyes suggests the involvement of alternative posterior segment regulatory mechanisms. These findings suggest good short-term biocompatibility of full-spectrum lighting and provide insight into refraction-dependent light-eye interactions in children with intermittent exotropia; however, longitudinal studies are needed to determine whether these acute effects translate into sustained ocular changes and to assess potential rebound effects.
He et al. (Sun,) studied this question.
