Background and aim: Sildenafil is used to treat erectile dysfunction but it has association with some side effects. This study was conducted with the aim of investigating the effect of duration of taking sildenafil on intraocular pressure (IOP) in patients with erectile dysfunction.
Methods: The study population of this cross-sectional study were all males with erectile dysfunction referring to the urology clinic affiliated to Rafsanjan University of Medical Sciences (Kerman, Iran) over a one-year period (2015-2016) among whom 110 patients were included in the study. After medical examinations and required investigations, a weekly dose of 25-100mg sildenafil (50 mg per week on average) was prescribed for patients. IOP in these patients was measured by an ophthalmologist before, one month after and three months after taking medication respectively. Finally, data were analyzed by SPSS version 16 using repeated measures test.
Results: Mean IOP before taking medication as well as one month and three months after taking sildenafil was 14.88±1.3, 15±1.28 and 15±1.34 mmHg respectively. Analysis of results showed that the difference in IOP in various periods of measurement was significant (p<0.001). Mean IOP before taking sildenafil was significantly different from three months after taking it (p<0.001) and mean IOP one month after taking sildenafil was significantly different from three months after taking it (p=0.002).
Conclusion: Results of this study indicated that taking sildenafil for three months increased IOP. Although these changes may not be clinically significant.

The worldwide spread of COVID-19 as an emerging, rapidly evolving situation, and the dramatic need of urgent medicine or vaccine, has rapidly brought new hypotheses for pathophysiology and potential medicinal agents to the fore. It is crucial that the research community provide a way to publish this research in a timely manner.
To contribute to this important public health discussion, the Electronic Physician Journal is excited to announce a fast-track procedure to help researchers publish their articles on COVID-19 related subjects that fall under the broad definition of public health, internal medicine, and pharmacology. We are especially welcome to all hypotheses about the pathological basis of the COVID-19 infection and the possible characteristics of potential medicine and vaccine. Submit your manuscript here
