Guo Y, Rokohl AC, Schaub F, et al. - Using three-dimensional (3D) stereophotogrammetry by assessing its reliability, researchers provided evidence for the periocular application of a novel anthropometric procedure. Participants in the study were 51 Caucasians (102 eyes; mean age, 31.9 ± 13.6 years). This imaging system is extremely reliable, along with the landmark recognition protocol. For comparison of reliability between different 3D imaging systems and populations, the gathered measurements and their mistakes can be implemented. It could be used to plan surgery and evaluate therapy results for doctors in ophthalmology, plastic and esthetic surgery, as well as in the maxillofacial field where periocular morphology changes are produced.
