What ıs a blocked tear duct ?

A blocked tear duct is when the eye’s drainage system for tears is either partially or completely obstructed. Tears cannot drain normally, causing a watery, irritated or chronically infected eye.
Most of your tears come from your lacrimal glands, which are located above each eye. The tears flow down the surface of your eye to lubricate and protect it, and then drain into tiny holes (puncta) in the corners of your upper and lower eyelids. The tears then travel through the small canals in the lids (canaliculi) to a sac where the lids are attached to the side of the nose (lacrimal sac), then down a duct (the nasolacrimal duct) before emptying into your nose, where they evaporate or are reabsorbed.

Inflammation (swelling), tenderness and redness of the inside corner of the eye or around the eye and nose.
Recurrent eye infections
Eye mucus discharge
Crusty eyelashes
Blurred vision
Blood-tinged tears

Sometimes, more than one treatment or procedure is needed before a blocked tear duct is fully opened. If an infection is suspected, your doctor will likely prescribe antibiotics.
A balloon catheter dilation procedure opens tear drainage passages that are narrowed or blocked by scarring or inflammation. General anesthesia is used. A narrow catheter (tube) with a deflated balloon on the tip is guided through the lower nasolacrimal duct. The doctor then uses a pump to inflate and deflate the balloon along the drainage system.
Surgery is usually the preferred option for people who develop blocked tear ducts. It is also effective in babies and toddlers with congenital blocked tear ducts, though usually an option only after other treatments have been tried.

I wish you all healthy days.
