PURPOSE: We aimed to evaluate the feasibility of using a modified Schirmer test
to determine the increase in tear volume after administration of 3% diquafosol
ophthalmic solution (diquafosol 3%) in dry eye patients. PATIENTS AND METHODS: A
randomized, multicenter, prospective, double-blind clinical study recruited 50
qualified subjects. They received diquafosol 3% in one eye and artificial tears
in the other eye. The study protocol comprised a screening and treatment
procedure completed within 1 day. The Schirmer test was performed on closed eyes
three times a day. The primary efficacy end points were the second Schirmer test
scores 10 minutes after the single dose. Secondary end points were the third
Schirmer test scores 3 hours and 40 minutes after the single dose and the symptom
scores prior to the second and third Schirmer tests. RESULTS: According to the
Schirmer test, 10 minutes after administration, diquafosol 3% significantly
increased tear volume compared to artificial tears. Diquafosol 3% and artificial
tears both showed significant improvements in the symptom scores compared to
baseline. However, there was no significant difference in the symptoms score
between diquafosol 3% and artificial tears. CONCLUSION: The modified Schirmer
test can detect a minute change in tear volume in dry eye patients. These
findings will be useful in the diagnosis of dry eye, assessment of treatment
benefits in daily clinical practice, and the development of possible
tear-secreting compounds for dry eye.
