Purpose: To assess the sensitivity and specificity of lateral midpupil lid distances for the detection of upper lid lateral flare.
Methods: Lateral lid flare was determined by unanimous agreement among six experienced oculoplastic surgeons in the grading of photographs obtained for patients with Graves orbitopathy (GO). Bézier lines were employed to extract the upper eyelid contours of the patients and a control group of age and sex matched subjects. Custom software was employed to determine 5 lateral midpupil eyelid distances. The sensitivity and specificity of each measurement in detecting lateral flare were estimated from receiver operating characteristic curves. The non-parametric Kruskal-Wallis one-way analysis of variance (ANOVA) with Dunn's posthoc test was used to compare the median values of the contour parameters between groups.
Results: The degree of agreement between judges evaluated with the Fleiss' Kappa test was relatively high (K = 0.69, z = 16.6, < .0001). The raters classified 12 lids with lateral lid flare (LLF) and 7 without LLF in patients with GO. There was no agreement on the presence or absence of LLF in 11 lids. In all eyes, lateral midpupil lid distances diminished from the center of the eyelid towards the lateral canthus. Receiver operating characteristic analysis for the midpupil distances revealed that the fourth distance from the center demonstrated high sensitivity and specificity in detecting flare. At this location (2.5 mm medial to the lateral canthus) a midpupil distance equal to or greater than 60% of the margin reflex distance (MRD) indicated the presence of flare.
Conclusions: A single measurement of a lateral midpupil eyelid distance 2.5 mm medial to the lateral canthus is a sensitive and specific measurement for the diagnosis of the LLF.

Purpose: To assess the efficacy of lower eyelid retraction surgery utilizing autologous auricular scapha cartilage (located within the anterior surface groove between the helix and anti-helix) and to present the surgical outcomes in a patient cohort.
Methods: Medical records of 21 patients who underwent lower eyelid retraction surgery with scapha cartilage were retrospectively reviewed. Retractions, present for an extended duration (6 months to 20 years), exhibited 1 mm or more inferior scleral show, attributed to prior lower eyelid blepharoplasty, facial palsy, or as a normal anatomical variation.

Background: Existing evaluation tools of tear trough deformity are based on subjective impression of clinicians. More accurate quantitative assessment methods are needed. This study aimed to propose a quantitative three-dimensional assessment method for the tear trough deformity in comparison with the Barton's grading system and apply it to the efficacy evaluation of orbital septum fat transposition.

Purpose: The purpose of this study is to compare the palpebral fissure shape after rim-off deep lateral decompression with and without restoration of the lateral orbital rim.
Methods: Retrospective cross-sectional quantitative analysis of the palpebral fissure images of 17 patients (25 eyes) who underwent rim-off deep lateral orbital decompression without repositioning of the rim (G1) and of 20 patients (34 eyes) operated with rim restoration. Quantification of palpebral fissure images included MRD 1 and MRD 2 , two lateral mid-pupil lid margin (MPD) distances, the width of the palpebral fissure, and the height and shape of the lateral canthus.
Background: Precise injection technique is vital for avoiding suboptimal eyebrow position when treating glabellar lines with botulinum toxin type A.
Objectives: The aim of this study was to evaluate the impact of glabellar injection technique on eyebrow position in patients treated with DaxibotulinumtoxinA for Injection (DAXI).
Methods: This retrospective post hoc analysis involved 60 adults who received a single treatment with DAXI 40 U to the glabella and had standardized facial photography.

Purpose: To evaluate the effect of orbital decompression on the upper eyelid contour.
Methods: A paired cross-sectional analysis of the upper eyelid contour was performed for 103 eyes of 66 patients who underwent orbital decompression. A control group of 26 normal subjects was also included.
