A man was diagnosed with syphilis in his eyes after going to hospital with a headache.
The 39-year-old in Sydney, Australia, went to the emergency room after suffering with headaches for three weeks.
His pain had been getting worse when he moved his eyes but he said his vision was still normal.
When doctors looked at the back of his eyes they noticed the optic nerves, which send information to the brain, were swollen, the medics revealed in a case report.
Further tests revealed that he was infected with syphilis, a sexually-transmitted infection which had spread there from his genitals – it is capable of spreading all over the body if left untreated.
A photograph of the inside of the man’s eye revealed the end of his optic nerve, also known as the nerve disc (it is visible as a circular shape in the centre of the image) was swollen because of the syphilis infection
The man had various medical tests and exams, including having fluid taken from his spine, before a blood test revealed syphilis-causing bacteria.
Syphilis is caused by bacteria called Treponema pallidum and it is most often spread by unprotected sex.
The patient, who was not named, told doctors he was ‘in a same-sex open relationship and engaged in casual unprotected sexual encounters with several male partners’.
Syphilis is a dangerous infection because many people don’t have any symptoms, meaning it can go unnoticed for years and spread through the body.
If this happens, it can infect the brain in a complication called neurosyphilis or even the eyes, as in this case, in what is called syphilitic optic neuritis.
The eye infection may affect as few as one in 100 people who get syphilis, said Jason Yosar from the Sydney Eye Hospital, where the man was treated.
In Europe a record-high number of people were diagnosed with syphilis in 2017, with a total of 33,189 confirmed cases.
Around 7,000 people in the UK were diagnosed with it, and in the US there were 35,000 cases of the STI in 2018.
According to Mr Yosar’s paper in the medical journal BMJ Case Reports, this could mean between 330 and 3,500 people in Europe or the US may have had the disease spread to their eye.
This patient’s specific case – having this condition in both eyes and not having HIV – is thought to have only been reported twice before in scientific journals, Mr Yosar said.
‘Syphilis must be considered as a diagnosis in all cases of optic nerve swelling, especially as early treatment with penicillin remains effective with high cure rates,’ Mr Yosar wrote.
The patient was treated with injected antibiotics for two weeks and made a complete recovery.
