“…In our study, except for ConjE (0.10) in NP and HPF (0.52) in DP, the ICC score for all the other 22 measurements (among the 24 measurements) was more than 0.76, which indicated that our study had reliability ranging from "good" to "very good" for repeated measurements on the same image for both NP and DP. Furthermore, the score of MRD (18,19) showed high reliability for both NP (0.97) and DP (0.98) and was consistent with the previous research (12), which also proved that our novel method is a potential standard tool to measure the LET based on 3D technology.…”

“…In this study, we aimed to investigate the possibility of indirectly evaluating LET using a 3D imaging system, VECTRA M3 stereophotogrammetry device. Our study findings confirmed the feasibility of using a digital imaging system to accurately perform DT (12). In addition, this study was the first to use a series of detailed periocular landmarks in the DT; this study is also the first to validate the feasibility of the corresponding inter-landmark measurements.…”

“…Recently, Stuchi et al (12) were the first to validate the reliability of a 3D imaging system to quantitatively evaluate lower eyelid laxity. However, they only investigated one parameter, the change in vertical distance of the lower eyelid between NP and DP, which is insufficient to fully assess the applicability of this method.…”

“…With the development of this new technique and the meticulous efforts required during eyelid reconstructive surgeries, high-resolution 3D stereophotogrammetry has been utilized in the periocular anthropometric evaluation of normal periocular parameters and the selection of optimal surgical technique (11). Recently, Stuchi et al were the first to investigate the potential use of a 3D imaging system based on the distraction test (DT) to assess LET (12). Their results confirmed the accuracy and reliability of a functional test based on a 3D digital imaging system (12).…”

Background: Standardized pre-operative assessment of the lower eyelid tension is essential to determine the optimal surgical technique. However, quantitative analysis using the conventional distraction test is inaccurate and user-dependent. Our purpose was to introduce a novel, standardized three-dimensional distraction test for measuring lower eyelid tension and to determine its standard values in a Caucasian population.Methods: In 94 participants (50 men and 44 women; age 21-85 years), a 15.9-g weighted eyelid hook was used to pull down the lower eyelid. Two three-dimensional images were acquired with a VECTRA M3 stereophotogrammetry device-one in the neutral position without a hook and the other in the distracted position with the eyelid hook. The images of all participants in both positions were measured twice by a single observer.Results: There was no clinical (>1 mm) or statistically significant difference between the two repeated measurements of all the inter-landmark linear distances in both positions (P≥0.05, respectively). The mean distracted displacement between the neutral and distracted position for margin reflex distance was 5.50±1.53 mm, without any age-specific difference (P=0.08); however, a significant gender-specific difference was observed as men had significantly greater displacement than women (P<0.001).Conclusions: Our proposed standardized three-dimensional distraction test for assessing lower eyelid tension using an eyelid hook and a simple landmark-based system seems to provide high reliability. This novel and simple method might be helpful for the preoperative planning of eyelid surgeries.

Standardized Three-Dimensional Lateral Distraction Test: Its Reliability to Assess Medial Canthal Tendon Laxity

et al. 2021

View full text Add to dashboard Cite

Background Assessment of MCT laxity is critical to the surgery options. Our study aimed to analyze the reliability of measuring medial canthal tendon (MCT) laxity by using a novel standardized three-dimensional lateral distraction test (3D-LDT). Methods Forty-eight Caucasian volunteers (25 males and 23 females, 96 eyes) between 22 and 84 years of age (55.6 ± 18.6 years old) were included in our study. From a neutral position, the lower eyelid was gently pulled laterally along a horizontal line to define the most distracted position of the lower punctum. Both in the neutral and distracted position, standardized 3D images were acquired for each subject by two observers, and each image were measured twice by two raters. Four landmarks and six corresponding linear measurements were evaluated for intra-rater, inter-rater, and inter-method reliability. Results Intra-rater, inter-rater and inter-method reliability analyses of 3D-LDT revealed an intraclass correlation of more than 95%, a mean absolute difference of less than 1 mm, and a technical error of measurement of less than 1 mm. Measurements of relative error (2.59–12.04%) and relative technical error (1.83–16.05%) for the inter-landmarks distance from pupil center to the lower punctum were higher than those from limbus nasal center to the lower punctum (6.13–30.39 and 4.34–26.85%, respectively). Conclusions This study provided high reliability of the three-dimensional lateral distraction test (3D-LDT) for assessing medial canthal tendon (MCT) laxity, which were never evaluated by digital imaging system.
