Retinal dysplasia

From Cow
Retinal dysplasia in a calf with Neuropathic hydrocephalus[1]

Retinal dysplasia is a rare autosomal recessive congenital eye disease of calves worldwide[2].

This disease is characterised by calves born with impaired acuity due to retinal disease[3]. This disease may be unilateral or bilateral[4].

In cattle, retinal dysplasia cause blindness and affected calves require either corrective surgery or are culled[5].

This disease has been seen associated with bovine viral diarrhea infection[6].

Other congenital diseases such as microphthalmos, microcoria, microcornea, microlentia, cataracts, retinal detachment, anterior segment dysgenesis, acorea and proliferation of the anterior neuroectoderm[7].
