A US woman who presented to hospital in Missouri with a blind spot, blurred vision and photophobia was diagnosed with neurosyphilis.
Writing in BMJ Case Reports, clinicians highlighted that an MRI revealed the 49-year-old patient had optic neuritis of the right optic nerve.
Her visual acuity was 6/21 in her right eye and 6/6 in the patient’s left eye.
She was treated with steroids. After symptoms persisted, a lumbar puncture was performed, and cerebrospinal fluid analysis tested positive for venereal disease.
The patient recalled becoming ill with a diffuse rash between one to two months before coming to hospital.
Following a diagnosis of neurosyphilis, the patient was treated with a two-week course of daily intravenous penicillin.
Five weeks after treatment she reported that almost all of her ocular symptoms had resolved.
Her visual acuity at five months was 6/7.5 in her right eye and 6/6 in her left eye.
