Secondary enophthalmos caused by an untreated orbital blowout fracture can cause esthetic and functional disturbances. The esthetic defect is manifested by sinking of the superior sulcus and the hypophthalmic globe. Functional impairment of the eye can usually be a common complaint with restriction of eye motion and diplopia. Early diagnosis followed by repair of surgically correctable fracture...

We investigate the dynamical origin for the occurrence of asynchronous hyperchaos and chaos via blowout bifurcations in coupled chaotic systems. An asynchronous hyperchaotic or chaotic attractor with a positive or negative second Lyapunov exponent appears through a blowout bifurcation. It is found that the sign of the second Lyapunov exponent of the newly born asynchronous attractor, exhibiting...

Purpose This study evaluated outcomes of surgical treatment for enophthalmos after pediatric orbital blowout fracture. Associations fracture type, site, time from injury to treatment, and type procedure with were assessed. Methods The medical records 200 children adolescents (38 girls 162 boys) fractures treated in the authors' department 1975 2015 reviewed retrospectively. main causes accident...

Orbital injuries are often missed out when they occur concomitantly with other facial bone fractures. Clinical examination and plain radiographic findings alone may prove inadequate in the detection of orbital floor fractures. Refined imaging techniques like CT scans and MRI are immensely helpful in the diagnosis of orbital blowout fractures. A case of 'impure' orbital blowout fracture which we...

The self-guiding of relativistically intense but ultrashort laser pulses has been experimentally investigated as a function of laser power, plasma density, and plasma length in the blowout regime. The extent of self-guiding, observed by imaging the plasma exit, is shown to be limited by nonlinear pump depletion with observed self-guiding of over tens of Rayleigh lengths. Spectrally resolved ima...

II. OVERVIEW By definition, PBI violates the subarachnoid space and creates a potential CSF leak. In addition to leakage from entry or exit sites, a fistula may occur at a remote site because of skull fracture and a dural tear from a blowout mechanism. High-velocity missiles may create transients of extremely high intracranial pressure, which can produce fractures even in the base of the skull....

PURPOSE To investigate the surgical timing postinjury in regard to ocular motility in patients with orbital-floor blowout fractures. METHODS This study involved 197 eyes (92 right eyes and 105 left eyes) of 197 patients (154 males and 43 females, mean age: 29.0 years, range: 7-85 years) with pure orbital blowout fractures. All patients underwent surgical repair within 30 days postinjury and w...
