LACRIMAL TESTING WITH 0.25-PERCENT FLUORESCEIN BENOXINATE (FLURESS)

Purpose. A modified Jones test was used to determine if multiple drops of 0.25% fluorescein/benoxinate (fluress) could replace one drop of 2 % sodium fluorescein for Jones testing. Results. In Group I, one drop of 2% sodium fluorescein passed faster than three drops of 0.25% Flure ss (P=0.024). In Group ii, no statisical difference was noted using on e drop of 2% sodium fluorescein or six drops of 0.25 % fluress (P=0.27 87). Conclusions. Six drops of fluorescein/benoxinate instilled over f ive minutes mag he used for modifoed Jones testing. individuals less t han 50 years of age appear to have more rapid lacrimal transit times.
