Jo SJ, et al. - This trial entailed the scrutiny of age- and sex-related changes in baggy lower eyelids (BLEs) with the aid of a novel objective image analysis method, the orbital gray scale (OGS). A notable correlation was brought to light between the medial-central-lateral (M-C-L) classification and OGS with both age and sex. This, in turn, established that they could serve as potent objective assessment tools for BLEs.
