Sir,

Optic nerve avulsion is a rare presentation of ocular trauma. The diagnosis of this entity is often obscured by the presence of concomitant vitreous haemorrhage, which precludes the visualization of optic head excavation. Various electrodiagnostic and expensive neuroimaging studies have not proved helpful in substantiating the diagnosis of this entity in the early stages and may not be readily available in most of the centres. We herein present the two cases of traumatic optic nerve avulsion diagnosed on B-scan ultrasonography before the ophthalmoscopic picture became clear. The role of ocular ultrasonography, readily available with ophthalmologists, and relatively inexpensive imaging in the diagnosis of suspected optic nerve head avulsion has been highlighted.
