Four-dimensional (4D) Ultrasound Imaging of Optic Nerves and Optic Discs

Objective: To demonstrate diagnostic abilities of four-dimensional (4D) ultrasound in neuroophthalmology. Material and methods: The study was performed in 3 patients with optic nerve and optic disc pathology (papilloedema) using duplex sonograph Loqic 7 (GE) with abilities for 3D/4D imaging of various structures. The results were compaired with normal subjects without optic nerve pathology. Results: Typical 3D and 4D normal and pathological sonographic images were obtained from optic nerves, optic discs and the surrounded structures. Discussion: The 4D ultrasound imaging of the optic nerves and optic discs is a new neuroimaging method, additional to the routine ultrasound investigation. It helps the quick and non-invasive evaluation of the type, location and severity of their structural damage.
