An ocular hypertensive effect by sildenafil was also recently described in a sheep animal model. In addition, we would like to note that we are aware of 5 other studies that measured the effects of sildenafil ingestion on IOP and/or ocular blood flow of human volunteers that also reported no changes in systemic blood pressure at the time the measurements were made (e.g., Dundar et al., 2006; Foresta et al., 2008; Grunwald et al., 2001b; Koksal et al., 2005; Polak et al., 2003).

Clinical effects have been noted within 1230 min after dose administration to fasted patients (Eardley et al., 2002), but are delayed after a fatty meal (Nichols et al., 2002). In contrast, clinical studies have not found a direct association between sildenafil ingestion (commonly consumed as Viagra) and changes in IOP. Some ocular researchers seem to have expected a priori that sildenafil, as a systemic hypotensive agent, might evoke a reduction in IOP (and/or a direct reduction in blood flow to the optic nerve head) due to a decrease in ocular perfusion pressure. Effects of sildenafil and tadalafil on intraocular pressure in sheep: implications for aqueous humor dynamics. Roessler G, Vobig M, Walter P, Mazinani BA.

These results support our hypothesis that the open communication between the ciliary body stroma and the anterior chamber would allow a fluid flow in either direction, such that a vasodilator-evoked increase in plasma-like fluid into the AC likely accounts for the IOP elevation. Inclusion criteria was erectile dysfunction based on the International Classification of Diseases (ICD-10) - Criteria for Male Erectile Dysfunction.

Conclusion: Thereafter, there was a tendency for the systolic pressure to increase, but it remained significantly lower (P< 0.05, as paired data) than the control, baseline values when measured at 120 and 165 min post drug ingestion (Table 2). Zusman RM, Morales A, Glasser DB, Osterloh IH. The latter is a theoretical concept that is in general defined as a difference between mean arterial pressure and IOP.
