The schema of the relationships among the tear film breakup time (TBUT), higher order aberrations (HOAs), choroidal thickness (CT), and axial length (AL) from the results of the current study. The TBUT is associated significantly with the CT that is related to the AL. The TBUT is correlated with the corneal HOAs but not with the total ocular HOAs, whereas the AL is related to the total ocular HOAs but not to the corneal HOAs. Because the parasympathetic nervous system affects both the lacrimal glands and CT, the parasympathetic nervous system might be a common factor upstream in the association between the TBUT and the CT.
