WebA deficient showed dilated pupil and no response to light. Another similar clinical sign of vitamin A deficiency was reported by Issi and Gul (2010) that the vitamin A deficient cattle lost PLR. Matsuda et al. (1999) investigated the relation between PLR and vitamin A level. The result showed to stop shrinking. The pupillary light reflex (PLR) or photopupillary reflex is a reflex that controls the diameter of the pupil, in response to the intensity (luminance) of light that falls on the retinal ganglion cells of the retina in the back of the eye, thereby assisting in adaptation of vision to various levels of lightness/darkness.
