PERSISTANT PUPILLARY MEMBRANE In dogs and cats this membrane is usually resorbed during later fetal development and the first 6 weeks of life, leaving a clear pupillary aperture. It is not uncommon, however, for remnants of this membrane to remain for several months or longer. In general, small remnants spanning from one portion of the iris to another sometimes cross the pupil but they have no discernible visual consequences. Visual impairment may occur, however, if strands contact the cornea or lens and create an opacity within the visual axis.
