Miniprobe for lacrimal sac temperature measurement.

The hypodermic probe is presented as a portable and easily used instrument for assessing the temperature within the lacrimal drainage system. Its size makes it practical for clinic or office use. It is also acceptable to the patient and may be performed immediately prior to lacrimal syringings. We suggest that lacrimal sac temperatures may be readily measured and are helpful in assessing the degree of inflammation or the presence of mucus in the lacrimal sac.
