This duck is presented because of poor vision. Where is the lesion?
Looks like a cataract doesn’t it – here’s a rather beautiful close-up – beauty in the eye of the duck as well as of the beholder hey?! But notice that the pupil is always dilated – the problem is actually primarily retinal. The female offspring of this bird also seem to have vision problems – hopefully we’re en route to further investigations of a potential duck PRA!
