Comparative Study of the Effects of 1% Atropine on the Anterior Segment

Figure 3

TIA (R1) is measured between the axis of the iris and a line connecting the scleral spur (point A) to the inner corneal surface with a distance of 500 μm (point B). AOD 500 (segment B to C) is the distance between the posterior corneal surface and the anterior iris surface, measured in a line perpendicular to the trabecular meshwork at 500 mm from the scleral spur.
