How to flush a nasolacrimal duct in a cat? - in detail
Flushing a nasolacrimal duct in a cat is a delicate procedure that should ideally be performed by a veterinarian or under their direct supervision. The nasolacrimal duct is responsible for draining tears from the eye to the nasal cavity, and blockages can lead to excessive tearing, discharge, or infections. The process begins with a thorough examination of the cat’s eyes to confirm the presence of a blockage. The cat is usually sedated or anesthetized to ensure it remains calm and still during the procedure. A local anesthetic eye drop may also be applied to numb the area. A small, flexible catheter or cannula is gently inserted into the punctum, the tiny opening of the nasolacrimal duct located at the inner corner of the eyelid. A sterile saline solution is then slowly flushed through the catheter to clear any obstructions. The fluid should exit through the nostril on the same side, confirming that the duct is now patent. If the blockage is severe, additional steps, such as using a contrast dye for imaging or repeating the flush, may be necessary. Post-procedure, the cat’s eyes are monitored for any signs of irritation, infection, or recurrence of the blockage. Antibiotic or anti-inflammatory eye drops may be prescribed to prevent complications. This procedure requires precision and care to avoid damaging the delicate structures of the eye and surrounding tissues. Owners should never attempt to perform this procedure at home without professional guidance, as it carries risks of injury or worsening the condition.
