Species: Dog
Condition: Persistent Pupillary Membranes
Organ System: Nervous/sensory
Persistent pupillary membranes are strands of tissue left over from the blood vessels which supplied nutrients to the eye before birth. These tissues should disappear by the time your pup is about a month old. In many cases even when the pupillary membranes do persist, they have no impact on your pet. In certain cases, however, they can cause cataracts and visual impairment. This disorder is most common in Basenjis and is also prevalent in Welsh corgis, chow chows, and mastiffs. You or your vet may notice white spots in your dog’s eyes or other signs of visual impairment. The condition can not be cured but the symptoms can be managed.
