Nasolacrimal Duct Cat -

Imperforate Puncta : Although more common in dogs, imperforate or micropuncta is seen in cats. It involves a membranous occlusion over the opening of the canaliculus. Atresia of the Distal Duct : Rare in cats, this involves the failure of the distal end of the NLD to open into the nasal cavity, leading to a cystic dilation of the duct (dacryops) or persistent epiphora from a young age.

The system begins at the lacrimal puncta, located on the palpebral conjunctiva near the medial canthus. The cat possesses both superior (upper) and inferior (lower) puncta, though the inferior punctum is clinically more significant for drainage. From the puncta, the canaliculi converge to form the lacrimal sac, which sits within the bony lacrimal fossa of the lacrimal bone. nasolacrimal duct cat

The nasolacrimal duct (NLD) is a critical component of the feline ocular adnexa, responsible for the drainage of tears from the ocular surface into the nasal cavity. While often overlooked in routine examinations, the NLD is frequently implicated in cases of epiphora and recurrent conjunctivitis in domestic cats ( Felis catus ). This paper reviews the anatomical trajectory of the feline NLD, contrasts its physiology with other domestic species, and discusses the pathophysiology of common clinical conditions such as dacryocystitis and imperforate puncta. Furthermore, current diagnostic approaches and therapeutic interventions, including flushing techniques and stenting, are evaluated. The system begins at the lacrimal puncta, located

Bacteria thrive in the damp fur, often creating a noticeable smell.
