To the Editor:Thank you, Drs Cruz and Garcia, for drawing my attention to our unintentional oversight in omitting the reference to your publication on radial mid pupil distances for eyelid contour analysis. This is an excellent article describing eyelid contour analysis, and we sincerely apologize for our oversight. You should certainly be commended for your excellent work on eyelid contour analysis, and my hope is our field will continue to move more toward mathematical analysis of anatomy and outcomes as exemplified by your group.
