Fig. 4. Big bubble (BB) diameters at different intraocular pressures (IOPs).
Box and whisker plots of BB diameter in the physiologic versus non-physiologic IOP groups (p=0.0003, n=18 in each group) (a) and six different IOP groups (n=6 in each group) (b). In the latter, significant differences in BB diameter were seen between the 40mmHg IOP group and 5, 10, 15, and 20mmHg groups (p=0.04, 0.02, 0.0001, 0.004, respectively). Dashed line corresponds to trephine diameter of 8mm.
