Disease Description: Inability to see in daylight.
Inherit Mode: The condition is thought to be inherited as autosomal recessive trait.
Disease Symptom: Signs are usually apparent in dogs 8 to 10 weeks of age. Hemeralopic dogs show severe loss of vision both in daylight and in high levels of artificial illumination, but such dogs become less insecure when placed in dim lighting. Recovery of vision takes several minutes, though loss of vision on returning to bright light is immediate.
