Species: Dog
Condition: Persistence of the Hyaloid System & Posterior Lenticonus
Organ System: Nervous/sensory
Hyaloid artery has a role in the proper development of the lens in foetuses. It should be gone at birth. However, sometimes it persists, causing formation of scars on the posterior lens surface. They can be seen with special ophthalmologic equipment as dark spots on the lens and inside of the eye. This anomaly varies in its severity, ranging from no symptoms to complete underdevelopment of the eyeball associated with other eye defects. Depending on the symptoms, the vet will proscribe therapy. Unfortunately, treatment is focused only on palliating the symptoms. As this anomaly is hereditary, affected animals should not be bred.
