Teaching NeuroImages: sonographic "retrobulbar spot sign" in differentiating etiologies of sudden visual loss.

Retrobulbar Spot Sign Predicts Thrombolytic Treatment Effects and Etiology in Central Retinal Artery Occlusion.

BACKGROUND AND PURPOSE Transorbital sonography may help establish diagnosis of central retinal artery occlusion (CRAO). Next to Doppler sonographic proof of CRAO, an intra-arterial spot sign can be detected in some cases. We hypothesized that it reflects calcified components. It may be associated with embolization from atherosclerotic plaques and may negatively influence thrombolysis. METHODS...

Diagnostic and therapeutic doubts in retrobulbar neuritis in children.

Retrobulbar neuritis is often very complicated clinical entity. The most common cause of retrobulbar neuritis is demyelinating disease of CNS. This report is to express some other uncommon causes of it. Three children, age 8 to 12 with sudden and severe visual loss are presented. The diagnosis of retrobulbar neuritis is made by complete ophtalmological examination in consultation with neuropedi...

Guidance of retrobulbar injection with real-time tomographic reflection.

OBJECTIVE Retrobulbar and peribulbar injections are common ophthalmologic procedures used to deliver anesthetics and other medications for ophthalmic therapy and surgery. These injections, typically performed without any type of guidance, can lead to complications that are rare but visually devastating. The needle may penetrate the optic nerve, perforate the globe, or disperse toxic quantities ...

[Retrobulbar optic neuritis associated with Infliximab].

CASE REPORT We report the case of a 76-year-old woman who attended our hospital because of a sudden loss of visual acuity in her left eye. The problem appeared to be that of retrobulbar optic neuritis. However, the age of the patient together with the simultaneous use of Infliximab to treat her rheumatoid arthritis, suggests the demyelination may have been associated with the Infliximab use. ...
