In-Clinic Detection of Optic Disc Drusen Using Hand-Held Ultrasound Technology

Neuro-ophthalmologists commonly receive referrals for possible papilloedema. One common cause of oedematous-appearing optic nerves is optic disc drusen (ODD). We describe a novel, handheld, portable ultrasound device that can be used to identify ODD in cases of suspected papilloedema. We demonstrate here that this portable ultrasound system can detect ODD in the outpatient ophthalmology and neurology settings. The portable version demonstrates several advantages. The device can be carried into the office, readily reducing visit times and office space. It is much more affordable than a traditional ultrasound machine. Images can be uploaded to a secure server and imported into the patient's chart. These cases represent one potential ophthalmological application of this novel technology that could augment the ophthalmological examination and improve patient care in the future.
