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...
Retrobulbar hemorrhage and permanent visual loss are rare presentations following traumatic asphyxia. In this case, bilateral permanent visual disturbance developed in a woman after chest-crushing trauma without direct trauma to the orbits. A computed tomography scan confirmed bilateral retrobulbar hemorrhages. An ophthalmologic exam revealed bilateral subconjunctival hemorrhages and severe lid...
Retrobulbar hemorrhage is a rare complication that may occur after mid-face injuries or following soft and hard tissue surgery around the eyes. The cardinal signs and symptoms of retrobulbar hemorrhage are pain, diplopia, ophthalmoplegia, a progression of increasing proptosis, and decreasing visual acuity leading to blindness. The diagnosis can be confirmed with computed tomography (CT) of the ...
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 ...
Retrobulbar hemorrhage, especially when associated with visual loss, is a rare but significant complication after facial bone reconstruction. In this article, two cases of retrobulbar hematoma after surgical repair of blow-out fracture are reported. In one patient, permanent loss of vision was involved, but with the other patient, we were able to prevent this by performing immediate decompressi...
