A man was admitted to a hospital after having a ‘powerful orgasm’ that caused him to go blind in one eye during sex.
According to the British Medical Journal, the ‘29-year-old man went to the emergency eye clinic to report an obstruction in the central vision of his left eye, which he had noticed on waking that morning’.
Doctors suspected that the man in question performed what they described as ‘Valsalva maneuveur,’ a move that resulted in tensing of abdominal muscles, straining and holding the breath, in which air is forced against a closed windpipe and pressure increases in the chest.
In the research carried out by the doctors, they said the pressure resulted in the popping of blood vessel in the eye of the unfortunate man after an episode of ‘vigorous sexual intercourse’, doctors concluded after speaking to him.
‘The diagnosis was unclear and the patient was asked to return for follow-up three days later.
‘At this visit, he saw a different clinician who asked direct questions about the patient’s sexual activity.
‘The patient then reported an episode of vigorous sexual intercourse on the evening preceding the onset of symptoms.
‘This directed history led to the diagnosis of postcoital valsalva retinopathy. Valsalva retinopathy is managed conservatively and is a self-resolving condition with an excellent prognosis.’
Haematologists also found out that ‘Valsalva manoeuvre’ can also produce memory loss.
A 1998 study revealed that the intense pressure in the brain’s blood vessels resulted in temporary lack of blood flow to the central part of the brain, which in turn, resulted in amnesia.
