Repair of anomalous nasolacrimal duct in a bull by use of conjunctivorhinostomy.
A proximal nasolacrimal duct anomaly, believed to be congenital, in a bull was repaired by use of conjunctivorhinostomy. Initial attempts at correction, using prolonged nasolacrimal duct catheterization, were unsuccessful. Trephination from the medial canthus to the ventral nasal meatus, combined with long-term catheterization of this new passage, was successful in resolving clinical signs of disease.
