Retrobulbar injection has been widely practiced as a technique of ocular anesthesia for many decades. Nevertheless, the technique is not free from complications. Vascular occlusion secondary to retrobulbar injection is rare but can be vision threatening. We report a case series of two such patients who presented with poor vision following retrobulbar injection. Fundus showed pale retina with ch...
Background. The relation between glaucoma and retrobulbar circulation in the prognosis has been indicated. Purpose. To investigate the effects of acupuncture on retrobulbar circulation in open-angle glaucoma (OAG) patients. Methods. Eleven OAG patients (20 eyes with OAG) who were treated by topical antiglaucoma medications for at least 3 months were enrolled. Acupuncture was performed once at a...
The evaluation of the retrobulbar orbital fat tissue and optic nerve with strain ratio elastography.
AIM The aim of this study was to evaluate the diagnostic performance of strain ratio elastography in the assessment of retrobulbar orbital fat tissue. MATERIALS AND METHODS The retrobulbar fat tissue of 14 eyes in 14 participants was scanned by sonoelastography. All the participants had permanent vision loss secondary to glaucoma in at least one eye. The elasticity scores were determined and ...

BACKGROUND AND PURPOSE This study was to evaluate the retrobulbar hemodynamics in patients who have transient monocular blindness (TMB) without carotid stenosis. METHODS Fifty-nine patients who have TMB without carotid stenosis were studied along with 59 age- and sex-matched controls. Color Doppler-imaging was used to study the retrobulbar hemodynamic by measuring the flow velocities (peak-sy...
