Abstract Purpose:When releasing a lacrimal punctum obstruction, it is necessary to estimate the original lacrimal punctum based on the traces of the ring of the lacrimal punctum, the running of blood vessels, the shape of the eyelid and a comparison of the shape of the left and right eyelids. In this study, we devised a method of accurately incising the obstructed lacrimal punctum by inflating it with lidocaine jelly(jelly)in cases of lacrimal punctum obstruction on one side of either the upper or lower lacrimal punctum.

Cases and Methods:A 72-year-old woman (Case 1) with bilateral upper lacrimal punctum membranous obstruction(Grade 1 aperture classification)and a 73-year-old woman (Case 2) with left lower membranous lacrimal punctum obstruction(Grade 1 aperture classification)underwent lacrimal punctum incision using the lacrimal punctum inflation technique. The lacrimal punctum on the open side was dilated, and jelly was injected through the dilated lacrimal punctum using the catheter of a 23-gauge vascular indwelling needle. A 27-gauge sharp needle was used to incise the area where the obstructed lacrimal punctum has been raised by the jelly. When the lacrimal punctum was less inflated, jelly was injected while applying pressure to the inner eye angle with a finger.

Results:In Case 1, the lacrimal punctum of right was inflated. The lacrimal punctum of left became partially thin and inflated, and jelly began to leak. In Case 2, the lacrimal punctum was less prominent, and the lacrimal punctum became inflated when jelly was injected while applying finger pressure to the inner eye corner. In all cases, a 27-gauge sharp needle was used to incise the inflated area or the area that had thinned and jelly had leaked out. When the lacrimal punctum was incised, jelly overflowed from the lumen of the lacrimal duct, confirming that the lacrimal punctum could be opened.

Conclusion:In a case of unilateral lacrimal punctum obstruction, the lacrimal punctum could be accurately opened by performing the lacrimal punctum inflation technique.
