Guo Y, Rokohl AC, Schaub F, et al. - Among 51 Caucasians (102 eyes; mean age, 31.9 ± 13.6 years), researchers intended to generate a proof for the periocular application of a new anthropometric procedure using three-dimensional (3D) stereophotogrammetry by assessing its reliability. For each individual, they obtained two sets of 3D images. On each image, two measurement sessions were performed by two raters. They found 52 periocular landmarks, and then assessed 49 corresponding linear, curvilinear, and angular measurements for intrarater, interrater, and intramethod reliability. Findings revealed the high reliability of this imaging system and the landmark identification protocol. For comparing reliability among many 3D imaging systems and populations, the applicability of the gathered measurements and their errors was suggested. Its use is suggested in planning operations and assessing treatment results for physicians in ophthalmology, plastic and esthetic surgery, as well as in the maxillofacial field where periocular morphology changes are made.
