Atypical cyclopia in a brown swiss cross calf: a case report.

In this report, an atypical form of cyclopia is described in a stillborn Brown Swiss cross male calf. The changes were confined to the head. The most significant malformation was the presence of a median orbita-like opening that did not contain an eyeball. Other defects included prosencephalic aplasia, brachygnathia superior and arrhinia. The possible cause of this congenital defect could not be ascertained.
