Assessment of age‐ and sex‐related changes in baggy lower eyelids using a novel objective image analysis method: Orbital gray scale analysis

Abstract

The M-C-L classification and OGS were significantly associated with both age and sex, proving that they could be potent objective assessment tools for BLEs.

A quantitative, objective method for evaluating the surgical outcomes of baggy eyelid correction using orbital gray scale analysis

“…We have previously conducted an objective analysis of nasolabial wrinkles by using linear gray scale analysis and have devised a similar method for analyzing objective values for BLEs . This method, called the OGS, uses ImageJ software (National Institute of Health, Bethesda, MD, https://imagej.nih.gov/ij/) to objectively obtain the respective scores of medial, central, and lateral lower eyelid fat.…”

“…The OGS measures the difference of the gray scale value between the lower eyelid fold and the surrounding area. The detailed definition of the OGS has been described in our previous study . Moreover, we newly defined the sum of the medial, central, and lateral OGS values as the “total OGS” to reflect the entire area of eyelid fat.…”

“…The OGS considers the fact that bulging of lower eyelid fat darkens the baggy infraorbital fold compared with the surrounding skin. The average OGS values measured in 104 Korean patients in our previous study were 13.0 for medial OGS, 14.9 for central OGS, and 7.50 for lateral OGS . In this study, we attempted to apply the OGS to objectively measure the changes after surgery and to analyze the obtained values in order to test the clinical applicability of this evaluation method.…”

“…As aging progresses, baggy lower eyelids (BLEs) become apparent owing to tear trough deformity and protrusion of the temporal, nasal, and central lower eyelid fat pads. The severity of BLEs is defined, according to the degree of fat prolapse, as medial (M), medial and central (MC), and medial to lateral (MCL) types . As infraorbital fat herniation is the main reason for the deformity, blepharoplasty for fat reduction has been the main treatment of choice.…”

“…These scales are all different and subjective and need special training to efficiently assess each score. The orbital gray scale (OGS), defined in our previous study, is a novel and the only assessment method that objectively calculates the severity of BLEs by using continuous variables.…”
