Condition Intervention
Health
Other: No treatment

Study Type: Observational
Study Design: Observational Model: Ecologic or Community
Time Perspective: Prospective

Further study details as provided by Allergan:

Primary Outcome Measures:
  • Eyelash Length as Measured by Digital Image Analysis (DIA) [ Time Frame: Baseline ] [ Designated as safety issue: No ]
    Photographs were taken of the eyelashes. Length was measured in millimeters. Data from both eyes were averaged for each participant for analysis.


Secondary Outcome Measures:
  • Eyelash Thickness as Measured by Digital Image Analysis (DIA) [ Time Frame: Baseline ] [ Designated as safety issue: No ]
    Photographs were taken of the eyelashes. Eyelash thickness/fullness was assessed across both eyes as an average of the 3 preset areas measured in millimeters squared (mm^2).

  • Eyelash Darkness as Measured by Digital Image Analysis (DIA) [ Time Frame: Baseline ] [ Designated as safety issue: No ]
    Photographs were taken of the Eyelashes. Eyelash darkness (intensity) was measured within the spline (a narrow area approximately 5 pixels wide that bisects the area of interest). Eyelash darkness was measured in both eyes and averaged for analysis using a scale where 0=black and 255=white.
