Orbital Plasmacytoma Mimicking an Orbital Abscess

Ophthalmic Plastic & Reconstructive Surgery, 2017
An 83-year-old male with a 15-month history of multiple myeloma presented with acute onset of swelling, redness, and pain around his right eye. CT scan was consistent with an orbital abscess. The patient was taken to the operating room for drainage of the orbital abscess. Abnormal tissue was encountered intraoperatively so biopsies were taken.

The Value of Orbital Echography in Orbital Practice

Ophthalmic Plastic & Reconstructive Surgery, 1998
Twenty-three consecutive patients with orbital masses who were referred to a major medical center and later had biopsies underwent ophthalmic echographic evaluation. The efficacy of orbital echography was compared with both the clinical evaluation and other orbital imaging methods (computed tomography and magnetic resonance imaging).

Orbital tuberculoma masquerading as an orbital malignancy

Australian and New Zealand Journal of Ophthalmology, 1997
Abstract Background: Orbital tuberculosis is exceedingly rare in areas where tuberculosis is non‐endemic. A case of childhood orbital tuberculosis is reported, which the authors believe to be the first reported case of orbital tuberculosis in the Australasian region.

ORBITAL EXPANSION FOR ANOPHTHALMIA AND MICRO-ORBITISM

Plastic and Reconstructive Surgery, 1977
In severe cases of microphthalmos or anophthalmos, the bony orbital cavity is often too small to allow one to create a satisfactory socket for a prosthesis. An omnidirectional expansion of the orbit, by osteotomies done in a step-like fashion, allows the creation of a larger bony cavity and improves the symmetry of the face. The risks of the craniotomy

Orbit–orbit interaction

The Journal of Chemical Physics, 1979
A new tensor expansion of the orbit–orbit interaction is derived straightforwardly in a form which is compact and completely symmetric in the coordinates of interacting particles. The m-scheme matrix element of the orbit–orbit interaction is then obtained as a concise sum of radial integrals.

Orbital myiasis in neglected orbital retinoblastoma

The National Medical Journal of India
We describe a 4-year-old girl with a white reflex since birth, who presented with orbital retinoblastoma, complicated with orbital myiasis as a result of lack of compliance to treatment. The patient was managed with orbital exenteration followed by adjuvant radiation therapy.

The k-orbit reconstruction and the orbit algebra

Acta Applicandae Mathematicae, 1992
The main achievement of this paper is a unified presentation of several well-known reconstruction problems in the single framework of an orbit reconstruction problem: If \(G\) is a permutation group acting on a finite set \(W=\{w_ 1,w_ 2,\dots,w_ n\}\) it has a natural action on the Boolean algebra \({\mathcal B}_ n\) of all subsets \(c_ j\), \(1\leq j\

Orbital Indications

2010
GKNS for uveal melanoma has become a recognized valued treatment which avoids enucleation of the eye. In the early days, the eccentric location of these tumors made treatment difficult, but Gamma Knife Perfexion has solved that problem. It is known that larger tumors and tumors with an anterior location have a worse prognosis.
