“…It was notable that both horses had moderate bacterial growth on aerobic culture of their ocular discharge. While a stand‐alone culture may not be sufficient to distinguish between active bacterial dacryocystitis and commensal microbiota, dacryocystitis has been described as a sequela of NLD obstruction of any etiology . Also, any neocanalization procedure in the region of the nasal mucosa must, by current classification, be considered contaminated .…”

“…Atresia of the nasolacrimal duct is the most common congenital anomaly of the nasolacrimal apparatus in the horse . While an imperforate nasal punctum is the defect most often described, atresia can occur anywhere along the course of the NLD . Foals presenting with this condition exhibit epiphora which progresses to mucopurulent ocular discharge with the onset of secondary bacterial dacryocystitis …”

“…The most common (traditional) definitive treatment for NLD atresia involves creating a new opening at the distal NLD . A polymer catheter, such as a silicone urinary catheter, is inserted normograde through the dorsal canaliculus and into the NLD until the point of occlusion is reached . An incision is then made through the nasal mucosa over the catheter tip to establish a new opening.…”

Case description A yearling Thoroughbred stallion and an 8‐year‐old Saddlebred mare were evaluated for persistent mucoid ocular discharge. Clinical findings Examination of both horses revealed copious yellow‐tan mucoid ocular discharge with a negative Jones I test, absent nasal punctum, and unsuccessful anterograde nasolacrimal duct (NLD) irrigation. Clinical abnormalities were present on the right side only in one horse and bilaterally in the other. Computed tomography (CT) with contrast confirmed nasolacrimal duct atresia in both horses. Treatment and outcome Under general anesthesia, the affected NLD was catheterized anterograde and contrast injected. Using fluoroscopic guidance, retrograde access to the distal NLD was obtained for through‐and‐through wire access. Over the wire, the stoma was dilated and a temporary stent placed for 4‐8 weeks. After the procedure, both horses were comfortable and free of ocular discharge at the minimum time of last follow‐up, 9 months postoperatively. Clinical relevance Fluoroscopically guided neocanalization is a viable alternative to traditional surgical approaches for NLD atresia, especially when access to the site of obstruction is limited.

Conjointement à l’amélioration de la connaissance des affections oculaires du cheval, les indications chirurgicales de certaines d’entre-elles se sont développées au cours de ces deux dernières décennies. Commencée avec la chirurgie des annexes de l’œil et celle du globe oculaire, la chirurgie oculaire chez le cheval a progressivement évolué pour inclure les affections de la cornée et certaines affections intraoculaires. L’élargissement des indications opératoires des affections de l’œil du cheval a été le résultat d’une évolution vers la spécialisation des méthodes diagnostiques et chirurgicales, et particulièrement pour ces dernières de l’utilisation de la microchirurgie oculaire. Le recul de plusieurs années de pratique a permis d’évaluer les bénéfices et les insuffisances de ces chirurgies oculaires. Dans un premier temps, cet article se propose de passer en revue la réalisation et les complications des chirurgies des annexes de l’œil (paupières et membranes nictitante) et celles du globe oculaire (l’énucléation et ses variantes). Ces chirurgies ont été associées car elles ont de nombreuses indications cliniques, et elles ont en commun d’être généralement simples à réaliser et de pouvoir être faites avec du matériel de chirurgie générale. L’étude de leurs possibles complications permet de mieux les anticiper, et de savoir minimiser leurs conséquences si elles apparaissent.
