Ophthalmologists, on occasion, take the initiative and the responsibility for prescribing systemic steroids to patients with vision-threatening ocular inflammatory disorders. Examples of such disorders include orbital pseudotumor, scleritis, uveitis, giant cell arteritis and optic neuritis. Preoccupation with the challenge and goal of preservation of vision, coupled with the propensity for some...

The regioselectivity of 1,3-dipolar cycloaddition reactions between mesoionic compounds with singly-tethered substituents is examined. The results with propitiate dipolarophiles are compared with other singly and doubly-tethered examples according to a model using an asynchronous, concerted transition state. The isolation and reaction of a novel, nonaryl substituted mesoionic compound 7 is repo...

The pleomorphic adenoma of lacrimal gland presents as a painless, progressive, slowly growing supero-temporal swelling with variable proptosis. This tumor is usually found in adults and extremely rare in teenage. We report a case of a 15-year-old boy with pleomorphic adenoma of lacrimal gland which mimicked pseudotumor of orbit due to its presentation as an orbital inflammatory disease and the ...

Incidence of orbital tumor is -3.5-4%. Tumors and tumorlike lesions of the orbit in children represent a different histologic spectrum than in adults. In the pediatric population, a delay in diagnosis of orbital tumors, even if benign, can lead to vision loss and deformity. Purpose of this study is presentation of epidemiology, clinical signs and symptoms, frequency and histopathology of orbita...

Idiopathic intracranial hypertension (IIH), or pseudotumor cerebri, is a condition of elevated intracranial pressure in the absence of clinical, laboratory or radiological evidence of an intracranial space occupying lesion that can occur in the pediatric population. While IIH is more commonly recognized as a disorder of adults, it affects children of all ages and can have distinctive characteri...

Alloplastic materials used for orbital fracture reconstruction can induce complications, such as infection, migration, extrusion, intraorbital hemorrhage, and residual diplopia. Silicone is one of the alloplastic materials that has been widely used for decades. The author reports a rare case of spontaneous extrusion of a silicone implant that was used for orbital fracture reconstruction 30 year...

The aim of this report was to discuss a complication resulting from a transconjunctival approach to treating an orbital fracture. A 30-year-old male patient presented with a fracture to the zygomatic orbital complex. He was treated with transconjunctival conventional surgical treatment. Two days after surgical treatment, the patient presented with secondary chemosis which was initially slight a...

Within the wide range of severity of orbital fractures, the small group of complex fractures causes most of the sequelae. Therefore identification of severe injuries and adequate treatment is of major importance. The introduction of craniofacial techniques made possible a wide exposure of even large orbital wall defects and their reconstruction by grafts. In spite of significant progresses, rep...

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...
