Most, but not all, of these patients had underlying anatomic or vascular risk factors for development of NAION, including but not necessarily limited to: low cup to disc ratio (“crowded disc”), age over 50, diabetes, hypertension, coronary artery disease, hyperlipidemia and smoking.

My husband is 13 years older than me, started having "unreliable" erections a few years ago (in his late 50's) This was causing me to feel insecure, thinking maybe he just wasn't turned on by me anymore.
