Man who lost his sight every time he had sex

A man was forced to seek medical help after going temporarily blind every time he had sex. No, this isn't a tabloid headline. It actually happens. The victim of this predicament never lost his sight with other strenuous physical activity except when he climaxed during intercourse. This is a rare but true phenomenon!  

 It was reported that was not due to embolism to the vessels (ophthalmic artery) supplying the eye as it is a recurring condition in this young man. It can be speculated that vasoconstriction of ophthalmic artery is the cause and the patient is treated with a vasodilator. I suspect that the patient may have an optic nerve with cup-disc at risk, meaning that the blood vessels traveling through a narrow space within the optic nerve. Vasodilator or baby aspirin could possibly help to prevent the transient mini-stroke/ visual loss in this patient and hot have to explain embarrassing health details to potential partners.
