Age-Related Changes and Cycloplegia-Induced Differences in the Human Crystalline Lens

The ocular biometric parameters of the human crystalline lens including anterior chamber depth (ACD), lens thickness (LT), radii of curvature of anterior and posterior lens (ALR and PLR), lens equatorial diameter (LED), and lens vault (LV), automatically quantified by the CASIA2 (SS-OCT; Tomey, Nagoya, Japan). Images of iridocorneal angle were obtained using CASIA2 and the Schlemm' s canal (SC) and trabecular meshwork (TM) were quantified manually. Both cycloplegia and non-cycloplegia images were obtained.
