Ocular lesions included microphthalmia, multiple PPMs (iris-to-iris and iris-to-lens), microphakia with cataract formation, myovascularised membrane surrounding the cataractous lens and expanding into the vitreous towards the retina, retinal detachment, and retinal dysplasia (Figure 2).
The retinal abnormalities (retinal dysplasia with occasional rosettes) observed in our fattening pig represent the disorganized development of retinal tissue that may be accompanied by pigment disturbance or evidence of associated retinal degeneration .
A rare form of optical, choroidal and retinal dysplasia
combined with an occipital encephalocele.
Certain breeds tend to inherit defects, such as hip dysplasia in German shepherds and retinal dysplasia
in Bedlington terriers.
(4) There can be many associated systemic features including progressive retinal dysplasia
, coloboma, congenital heart disease, microcystic kidney disease, liver fibrosis, polyldactyly and soft tissue tumors of tongue.
