Fluorophotometric measurement of the precorneal residence time of topically applied hyaluronic acid

Table 1 Turnover rates of topically applied 0.1% fluorescein hyaluronic acid (F-HA), 0.1% hyaluronic acid and saline obtained from 10 subjects
Subject no. Turnover rate (%/min)
F-HA Hyaluronic acid Saline
1 7.6 19.4 28.1
2 12.2 22.6 31.0
3 2.9 22.6 31.8
4 9.5 20.4 33.2
5 4.6 21.4 33.4
6 8.6 22.2 37.1
7 15.2 24.2 29.6
8 8.4 20.4 24.1
9 5.3 17.1 27.8
10 7.1 21.3 33.9
Mean (SD) 8.1 (3.6) 21.7 (2.8) 31.0 (3.7)
  • The turnover rate of F-HA was significantly lower than those of hyarulonic acid and saline (p = 0.00012 and p = 0.00000022, respectively; Mann–Whitney test).
