Correlation between the 2-Dimensional Extent of Orbital Defects and the 3-Dimensional Volume of Herniated Orbital Content in Patients with Isolated Orbital Wall Fractures
BACKGROUND The purpose of this study was to assess the correlation between the 2-dimensional (2D) extent of orbital defects and the 3-dimensional (3D) volume of herniated orbital content in patients with an orbital wall fracture. METHODS This retrospective study was based on the medical records and radiologic data of 60 patients from January 2014 to June 2016 for a unilateral isolated orbital...
متن کاملTeaching Video NeuroImages: positional exophthalmos in orbital varices.
A 56-year-old woman presented with intermittent vertical diplopia and exophthalmos of the left eye, which become apparent when she was bending over. Examination disclosed mild limitation of supraduction and lid lag of the left eye. Bending over induced profound exophthalmos of the left eye (video) and aggravated vertical diplopia.

متن کاملOrbital varices: a new technique for noninvasive diagnosis.
Orbital venous varices can be a perplexing imaging problem, as they typically are expanded only during periods of venous hypertension, which is transmitted cephalad owing to the lack of valves in the internal jugular veins [1]. When venous pressure is not elevated , orbital varices may collapse and be undetectable on routine imaging studies, such as axial CT scans of the orbit. A provocative te...
متن کاملExtraocular Muscle Fixation to the Orbital Wall
The surgical results of severe or complex deviations such as those due to complete third nerve palsy, aberrant innervation of extraocular muscles (EOMs) and Duane syndrome are usually not completely successful. Herein, we describe the surgical technique of EOM fixation to the orbital wall. After a limbal or fornix based conjunctival incision, the related EOM is identified and dissected; the mus...
