The acute effects of 50 mg of sildenafil on tear functions were evaluated in 12 impotent patients. Mean tear breakup time, cotton thread, and Schirmer I tests were 19.42±6.45 s, 13.92±6.63 mm, and 16.58±12.19 mm, respectively before sildenafil and 20.33±10.40 s, 10.92±6.14 mm, and 18.08±12.36 mm, respectively, 1 hour after sildenafil. The results suggest that sildenafil does not adversely affect tear functions.
