What researchers measure

Primary outcomes

  1. Percentage of Participants With at Least a 1-Grade Increase in Overall Eyelash Prominence Using the Global Eyelash Assessment Scale (GEA)

    The investigator evaluated the patient's eyelash prominence using the GEA 4-point scale: 1= minimal, 2= moderate, 3= marked and 4= very marked at Baseline and Month 4. At least a 1-grade increase in the GEA score from Baseline indicated improvement.

    Time frame: Baseline, Month 4

Secondary outcomes

  1. Change From Baseline in Eyelash Length as Measured by Digital Image Analysis (DIA)

    Photographs were taken of the eyelashes and assessed using DIA. Length was measured in millimeters (mm). Data from both eyes were averaged for each participant for analysis. A positive change from Baseline indicated longer length (improvement).

    Time frame: Baseline, Month 4

  2. Change From Baseline in Eyelash Thickness as Measured by DIA

    Photographs were taken of the eyelashes and assessed using DIA. Eyelash thickness (fullness) was assessed across both eyes as an average and is measured in millimeters squared (mm\^2). A positive change from Baseline indicated fuller eyelashes (improvement).

    Time frame: Baseline, Month 4

  3. Change From Baseline in Eyelash Darkness as Measured by DIA

    Photographs were taken of the eyelashes and assessed using DIA. Eyelash darkness was measured in both eyes and averaged for analysis using a scale where 0=black and 255=white. A negative change from Baseline indicated darker eyelashes (improvement).

    Time frame: Baseline, Month 4
