Anterior and posterior fetal nuclear elliptical angle measurements. From the center of the embryonic nucleus (black square), a 1 mm distance (white vertical line) is measured along the equatorial axis, and the fetal fiber(s) at this point is traced (black dots) anteriorly (a) and posteriorly (p) for a short distance. Transparent diabetic lenses (A) exhibited an average anterior fetal elliptical angle of 26° and posterior average of 28°. The anterior fetal elliptical angle of nuclear cataractous diabetic lenses (B) averaged 23° (a decrease of 12% from the transparent diabetics) and 25° for the posterior (an 11% decrease).
