Which term describes abnormally close orbital positioning?

Explanation:
Abnormally close orbital positioning is hypotelorism. It means the distance between the eye sockets is reduced, a finding you’d look for when evaluating fetal craniofacial development. This can be seen with midline defects such as holoprosencephaly, where midline structures fail to develop normally. Hypertelorism would be the opposite—an abnormally wide spacing between the orbits. Macroglossia is simply an enlarged tongue, and increased nuchal thickness refers to a thickened neck region, not the spacing of the orbits.
