Dacrocystogram is an injection of contrast dye into the tear duct openings of your eye lid to check for blockages and other pathologies in the ducts.

The dye is X-rayed as it is passes through the ducts and into your mouth. The study is performed by a Radiologist, is pain free and takes approximately 15 minutes.

This procedure is available at the following Dr Jones & Partners locations:


You are asked to lie flat on an X-ray table with a small cushion under your head. The radiologist will place a small cannula into the tear duct opening of your lower eye lid. A bright light or torch and magnifying equipment may be needed as the ducts are very small. You are asked to close your eye once the cannula is in place. A small amount of tape around the cannula tubing will also help hold the cannula in place against your cheek. You will be asked to remain very still when the contrast is injected as the ducts are very difficult to see on X-ray if you move. It takes just a few seconds to take the necessary pictures. The dye will pass into the back of your mouth if the ducts are functioning. Sometimes if the ducts are blocked the dye may well near your eye. This is perfectly safe and can be wiped away with a tissue. The process is usually repeated on the other eye.
