PURPOSE We present spontaneous retrobulbar hemorrhage in a 52-year-old woman with history of breast cancer and tamoxifen intake which was first thought to be an orbital metastasis. CASE REPORT A 52-year-old woman with history of breast cancer and tamoxifen intake was referred due to severe proptosis and visual loss. Orbital imaging showed an intra-conal mass. After exploration, multiple fragm...
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...
