DCR (Dacryocystorhinostomy)
Tears are made primarily by the lacrimal gland, which is anatomically located in the upper lateral aspect of the upper eyelid. With each blink, however, tears are drained from the eye through the tear drainage system, into the nose. There are normally two openings to the tear drainage system; one in the upper eyelid and one in the lower eyelid. These tiny orifices are situated along the margin of the eyelid, closest to the nose, and are known as puncta.
The puncta lead to tiny ducts known as canaliculi which lead to the lacrimal sac, situated just along the inside corner of the eye, on the side of the bridge of the nose. Tears are carried from the lacrimal sac down the nasolacrimal duct into the nose. It is usually toward the bottom of the nasolacrimal duct that obstructions of this passageway occur.
A test for obstruction of the nasolacrimal duct might include irrigation of the tear drainage pathways. This non-painful test is completed by placing a small, blunt irrigating syringe just inside the initial opening of the tear duct, and irrigating fluid (water or saline) through the tear drainage system. If the nasolacrimal duct is determined to be relatively or completely obstructed, a DCR procedure is often appropriate.
The DCR Procedure which I need to have done - In this procedure, the tear drainage pathways are reconnected to the inside of the nose. A small incision is usually placed approximately midway between the corner of the eye and the bridge of the nose. The lacrimal sac is located, incised, and then connected to the nasal mucosa creating a new tear drainage pathway.
Tiny plastic tubes (stents) are then placed in the newly created tear drainage pathway for a few months to prevent scarring of the tear drainage ducts, which might otherwise result in failure of the surgery. The tubes can usually be removed in the office with little if any discomfort or need for anesthesia.
