The aperture of the iris, through which tho rays of light pass that have to impress the image of an object on the retina. This aperture can be dilated or contracted so as to allow a greater or smaller quantity of luminous rays to penetrate. The pupil, in man, is round, and by it the anterior and posterior chambers of the eye communicate with each other. In the foetus, during the first six months of gestation, it is closed by the pupillary membrane.
