- a/b: Proportion of medial brow to total brow length.

- a/c: Proportion of medial to lateral brow length.

- e/f: Relationship between palpebral fissure height and eyebrow distance.

- e/g: Ratio of palpebral fissure height to intercanthal distance.

- d/f: Relative brow height compared to eyebrow distance.

- h/e: Horizontal brow span to vertical eye opening.

- i/f: Lower lid to brow height relative to eyebrow distance.

- d/i: Brow height to lower lid-to-brow height.

- j/e: Eye width to eye opening height.

- F-value/Inter-group = test statistic for between-timepoint comparisons.
