Follow-up has been limited in many of the reports; however, in approximately one-third of the patients, the hearing loss was temporary. Concomitant medical conditions or patient factors may play a role, although risk factors for the onset of sudden hearing loss have not been identified. Patients should be instructed to contact their physician if they experience changes in hearing. [12][15] A thorough ophthalmic examination, in addition to cardiovascular risk assessment, should be considered for patients prior to prescribing phosphodiesterase inhibitors. Ophthalmic adverse events reported by >= 2% of patients treated with sildenafil and which were more frequent on drug than placebo in clinical studies include visual impairment (3-11% vs.

5.7 Priapism
Post-marketing reports have included diplopia, temporary vision loss/decreased vision, ocular redness or bloodshot appearance, ocular irritation/burning, ocular swelling/pressure, increased intraocular pressure (ocular hypertension), retinal vascular disease or retinal hemorrhage (1.4%), vitreous detachment/traction, and paramacular edema, and epistaxis (9-13%). Non-arteritic anterior ischemic optic neuropathy (NAION) has also been reported rarely in patients using phosphodiesterase type 5 (PDE5) inhibitors. [85][86][87][88] Based on published literature, the annual incidence of NAION is 2.5-11.8 cases per 100,000 males >= 50 years of age per year in the general population. An observational study found that episodic use of PDE5 inhibitors was associated with acute onset of NAION and suggested an approximate 2-fold increase in the risk of NAION within 5 half-lives of PDE5 inhibitor use. It is thought that the vasoconstrictive effect of phosphodiesterase inhibitors may decrease blood flow to the optic nerve, especially in patients with a low cup to disc ratio.
Drug Interactions
Symptoms, such as blurred vision and loss of visual field in one or both eyes, are usually reported within 24 hours of use. Most, but not all, of these patients who reported this adverse effect had underlying anatomic or vascular risk factors for development of NAION. These risk factors include, but are not limited to: low cup to disc ratio (‘crowded disc’), age over 50 years, diabetes, hypertension, coronary artery disease, hyperlipidemia, and smoking. Additionally, 2 patients had retinal detachment, and 1 patient had hypoplastic optic neuropathy. [85] It is not yet possible to determine if these adverse events are related directly to the use of PDE5 inhibitors, to the patient’s underlying vascular risk factors or anatomical defects, to a combination of these factors, or to other factors.
