A dacryocystorhinostomy (DCR) is a type of surgery done to create a new tear drain between your eyes and nose. You may need this surgery if your own tear duct has become blocked.
Your eyelids have two small openings that drain some of the tears covering your eye. Blinking pushes tears into these openings. From there, the tears empty into a small tube and then into a larger area, called the lacrimal sac. This sac leads to the tear duct. This duct passes around some bony structures surrounding your nose and drains into your nasal cavity.
Sometimes, this drainage system gets blocked. This can cause a lot of tearing or discharge from the eye. The blocked duct often becomes infected as well.
In most cases, the cause of a blocked tear duct is not known. Other times, the blocked tear duct can be caused by health problems such as:
Anatomical problems you were born with
Chronic nasal infections
Obstruction from a tumour
Trauma to the nose
Conjunctivitis
Nose polyps
During a DCR, your surgeon creates a new opening from the lacrimal sac to your nasal cavity. The surgeon makes a small incision in the skin, in the area under your eye and next to your nose. Through this incision, your surgeon creates a small opening in the bone beneath. This opening then connects your lacrimal sac and your nasal cavity. Sometimes, the surgeon leaves a small tube there to help keep the new tear duct open.
