Parameters assessed included pupil size, IOP, and UBM\u2010derived measurements of the iridocorneal angle (ICA), angle opening distance (AOD), ciliary cleft width (CCW), length (CCL), area (CCA), ciliary body axial length (CBAXL), and ciliary process\u2013scleral angle (CPSA).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Tropicamide significantly increased IOP in the treated eye (OD) but not in the control eye (OS).
