Pupillary membrane is a fetal structure, which covers the pupil prior to Birth. Shortly after birth it resolves. Sometimes part or all of it persists, therefore, it is called persistent pupillary membrane (PPM). This disorder is hereditary but the way of inherence is unknown. Most cases of PPM are hot with visual deficits although sometimes some of those attending to the lens and cornea may cause blindness due to opacity.

In November 2002, A 3 month old European Short hair kitten referred for inspection and preliminary Vaccination to small animal hospital, faculty of Tehran University. During clinical examination, The PPM diagnosed in this case. Some of pupillary membrane strands were free and did not induce cataract and keratitis. There were no adhesions. PPM has been reported in dogs and cats. Animals with PPM shouldn't be bred.
