Iris of the Eye with a Persistent Pupillary Membrane
Are you curious about another fascinating eye condition? The persistent pupillary membrane (PPM) can give the iris a variety of interesting shapes, like the one shown here. This occurs when certain parts of the iris disappear during pupil formation. Fortunately, PPM does not affect vision since the brain is capable of filtering and correcting visual information.
Some individuals have PPM in both eyes while others have it in just one. It is often surprising to learn that this condition does not impact eyesight.
