A 12‐year‐old girl presented to a general practitioner with a two‐day history of progressively worsening blurry vision. The visual symptoms prompted the patient to be referred to the local optometrist. Blood pressure was not checked at this initial general practice visit. At the optometrist, fundoscopy revealed bilateral disc swelling, prompting urgent same‐day referral to our hospital's ophthalmology unit. There was no associated pain on extraocular eye movements, headaches, or diplopia. There was no past medical or relevant family history. However, her parents described abnormal behavioural patterns over the previous three months, including nocturnal enuresis, sleep walking, and wishing to take cold showers late at night.
