Primary Outcome Measures :
  1. Intra- Examiner Agreement in Angle Width by Goniometric Lens [ Time Frame: Day 1 ]
    Intra-rater agreement (for each of the 6 raters) of Large Step angle width (range: 0.5 to 5.5 with 0.5 unit intervals) was evaluated using weighted kappa (Fleiss-Cohen) statistics. The angle is the area between the iris and cornea of the eye. Each examiner performed a pair of angle-width measurements by goniometric lens predilation (ie, 2 measurements per examiner). The degree of agreement within raters was interpreted according to Landis and Koch, where: <0:poor, 0.00-0.20:slight, 0.21-0.40:fair, 0.41-0.60:moderate, 0.61-0.80:substantial, and 0.81-1.00:almost perfect.

  2. Inter- Examiner Agreement in Angle Width by Goniometric Lens [ Time Frame: Day 1 ]
    Inter-rater agreement (among 6 raters) of Large Step angle width (range: 0.5 to 5.5 with 0.5 unit intervals) was evaluated using weighted kappa (Fleiss-Cohen) statistics. The angle is the area between the iris and cornea of the eye. Each examiner performed a pair of angle-width measurements by goniometric lens predilation (ie, 2 measurements per examiner). The degree of agreement within raters was interpreted according to Landis and Koch, where: <0:poor, 0.00-0.20:slight, 0.21-0.40:fair, 0.41-0.60:moderate, 0.61-0.80:substantial, and 0.81-1.00:almost perfect.
