What exactly causes it:
Holding the breath while having sex is the main reason behind the pressure build-up which bursts the blood vessels and causes haemorrhage in the eyes. People often hold their breath during sex for experiencing stronger sensations, to get orgasms and men are known to do it for preventing ejaculation. Apart from haemorrhage, restricting your breath can even cause suffocation.

How severe is the damage:
The good news about the damage caused by orgasms is luckily not permanent. In this case, the 29-year-old regained his eye sight after the blood in his eye reabsorbed into his body.
"The autonomic effects of orgasm on the eye are well known and have been associated with other ocular pathology, including angle closure glaucoma [damage to the optic nerve due pressure build up]," the report concluded.
