Use of canaliculorhinostomy for repair of nasolacrimal duct obstruction in a horse.

The research article is about the use of a surgical procedure called canaliculorhinostomy as a treatment for nasolacrimal duct obstruction in a horse.

Research Objective

• The study aims to tackle the problem of obstructed nasolacrimal outflow, a not uncommon condition in horses, by proposing canaliculorhinostomy as a possible treatment. The issues can be caused by a variety of factors such as foreign bodies, trauma, or hereditary abnormalities.

Condition and Problem

• Nasolacrimal duct obstruction is a condition in horses that blocks the tear duct and prevents the natural flow of tears from the eyes to the nasal cavity. This is significant because tears provide essential lubrication for the eye and play a critical role in its health and overall comfort.
• Obstruction often happens due to the presence of foreign bodies, trauma to the eye or nasal region, or inborn abnormalities in the horse’s nasolacrimal duct structure.

Surgical Solution: Canaliculorhinostomy

• In dealing with the obstruction, the usual approach is to install a nasolacrimal retention stylette, however, it can be a challenging process.
• Instead, the research proposes a surgical procedure called canaliculorhinostomy as an alternative solution. It involves creating a new pathway for the tears to flow from the eye to the nasal cavity by making a direct connection between the canaliculus (the horse’s tear duct) and the nasal cavity.

Significance and Impact

• Should it be effective, this method may provide relief for horses experiencing discomfort from the condition and could drastically improve their ocular health and overall quality of life.
• This research offers new perspectives and choices for veterinary practitioners when dealing with nasolacrimal duct obstruction in horses, thus providing more options for its treatment and management.
