Original publication title: Atresia of the nasolacrimal orifice in two thoroughbreds.
Plain-English summary
In this study, two thoroughbred horses were found to have a condition called bilateral atresia of the nasolacrimal orifice, which means their tear ducts were blocked. Both horses had a constant eye discharge, with one having clear fluid and the other having a thick, pus-like discharge. The treatment involved creating a small opening to connect the blocked tear duct to their nasal cavity, and this procedure worked well for both horses.
Abstract
Two cases of bilateral atresia of the nasolacrimal orifice are described. The presenting sign was a persistent ocular discharge, clear in the one case and purulent in the other. Treatment by the creation of a fistula between the distal extremity of the blind ending duct and the nasal cavity was successful in both cases.
