Objective: This study was undertaken to establish and validate a new wrinkle clinical assessment scale to measure Chinese Han women`s validated lacrimal groove.

Methods: Three clinical investigators asked to rate lacrimal groove wrinkles severity one each side for 30 photographic images from 15 subjects. Five-grade rating scale has been used in this clinical assessment. Scale definitions was standardized by 6 researchers in visual and descriptive formats. Assessments were conducted independently and were repeated after 1 week.

Results: For 30 photos from 15 subjects, test-retest of three investigators analyzed by Spearman's correlation were between 0.967 and 0.993 (p < 0.001), and by ICC Cronbach's α were between 0.989 and 0.997 (p < 0.001); intraobserver agreement of three investigators analyzed by Spearman's correlation were between 0.652 and 0.897 (p < 0.001), and by ICC Cronbach's α were between 0.840 and 0.959 (p < 0.001).

Conclusion: This lacrimal groove wrinkles visual assessment scale is a valid and reliable instrument for quantitative assessment of China woman skin folds with inter- and intraobserver consistency. This assessment scale should prove a useful clinical tool by allowing objective and reproducible grading for assessing the effectiveness of lacrimal groove area.

: This study aims to compare the clinical findings, particularly symptomatic diplopia, associated with an inferomedial orbital strut fracture versus intact strut and to determine the clinical significance of the inferomedial orbital strut in patients with orbital floor and medial orbital wall fractures. : A 10-year retrospective observational study involving orbital blowout fracture cases was conducted in our institution. Patients with fractures of the orbital floor medial to the infraorbital groove and medial orbital wall, as seen on computed tomography (CT) scans, were included in this study.
