Ex vivo pupil dilation results. Images taken before (a) and after (b) the addition of 40 μL of 2.5% phenylephrine and 40 μL of 1% tropicamide to the bath solution. On the left is a top-down view of an iris with the anterior surface facing up using a digital camera and in the middle is the cross section of the iris detected by the OCT imaging system. The pupil diameter (arrows) is shown to visibly increase after the addition of the drugs.
