Oral fluorography. The Oral Fluorescein Study Group.

A cooperative study group was formed to evaluate the use and effectiveness of oral fluorography. The procedure is simple to perform, reliable, and side effects are almost negligible. Oral fluorescein provides valuable information when such information is required in a timely manner, or when late leakage of fluorescein is anticipated. It is also valuable for patients who fear intravenous injection of dye or who have relatively inaccessible veins.
