Acute Effects of Sildenafil on Humphrey Visual Field and Intraocular Pressure
2004
Purpose: To evaluate the effects of sildenafil on visual field and intraocular pressure in a group of healthy subjects. Methods: Twenty-eight healthy male volunteers with normal eyes were included in the study. Visual field examinations were performed using FASTPAC 30-2 program (white-on-white and blue-on-yellow) with the Humphrey field analyzer before and one hour after receiving oral 50 and 100 mg sildenafil citrate. Results: The mean age was 51.1 ± 8.9 years. Mean deviation, pattern standard deviation, short-term fluctuation and corrected pattern standard deviation did not differ significantly among tests both in white-on-white and blue-on-yellow visual field examinations. Changes in intraocular pressure were not statistically significant. Conclusions: No significant effect of sildenafil was seen on visual field and intraocular pressure in healthy subjects.
