Data show the forward ciliary body (FCB) movement in six rhesus monkey eyes before and after α-chymotrypsin injection. FCB was determined as the narrowing of the angle that is formed between the inner aspect of the cornea and the anterior aspect of the ciliary body in the accommodated versus the unaccommodated state measured in degrees (Fig. 13). The eyes received an α-chymotrypsin injection in the temporal quadrant. Measurements were taken in the region of the injection site. FCB movement was significantly higher after α-chymotrypsin (Post) versus before (Pre) by two-tailed paired t-test. Monkeys 1–3 were stimulated to accommodate by central electrical stimulation, and monkeys 4–6 were stimulated to accommodate pharmacologically by carbachol iontophoresis.
