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 ...
Cardiac perfusion studies using computed tomography are a common tool in clinical practice. Recent technical advances and the availability of dedicated small animal scanners allow the transfer of these techniques to the preclinical sector in general and to mouse models of cardiac diseases in particular. This necessitates new requirements for contrast injection techniques as a rapid transport of...
An experimental model for acute allergic optic neuritis was produced in adult strain 13 guinea pigs by sensitization with isogenic spinal cord emulsion in complete Freund's adjuvant. These animals exhibited two distinct clinical patterns: (1) "retrobulbar optic neuritis," with a diminished pupillary response to light despite a normal fundus, and (2) "neuroretinitis," with a diminished pupillary...
INTRODUCTION An altered perfusion of the optic nerve head has been proposed as a pathogenic factor in glaucoma. OBJECTIVE To evaluate changes of haemodynamic parameters in the retrobulbar arterial circulation after a decrease of elevated intraocular pressure (IOP) in patients with primary open angle glaucoma (POAG). METHODS Twenty-six patients were examined, 14 men and 12 women, 21 up to 50...
