Nylon foil (supramid) orbital implants in pediatric orbital fracture repair.

Purpose: To present the authors experience with the nylon foil (Supramid) implant as a safe and effective method to repair pediatric orbital wall fractures.

Methods: A retrospective chart review of all pediatric patients (≤18 years) that underwent orbital wall fracture repair with an unsecured 0.4-mm Supramid implant between 2007 and 2010.

The efficacy of radiotherapy in the treatment of orbital pseudotumor.

Purpose: To review institutional outcomes for patients treated with external-beam radiotherapy (EBRT) for orbital pseudotumor.

Methods And Materials: This is a single-institution retrospective review of 20 orbits in 16 patients diagnosed with orbital pseudotumor that received EBRT at the University of Oklahoma, Department of Radiation Oncology. Treated patients had a median follow-up of 16.

The efficacy of radiation therapy in the treatment of Graves' orbitopathy.

Purpose: To review our institutional outcomes of patients treated with radiation therapy (RT) for Graves' orbitopathy (GO), assess the role of orbital reirradiation, and identify prognostic factors of complete response (CR).

Methods And Materials: This is a retrospective review of 211 patients who presented with a diagnosis of GO and received RT between January 2000-2010. RT dose was 20 Gy in 10 fractions.

Progressive optic neuropathy in idiopathic intracranial hypertension after optic nerve sheath fenestration.

A 16-year-old woman complaining of headache and declining vision in both eyes had papilledema, normal brain imaging, and a lumbar puncture showing a moderately high opening pressure (35 cm H2O) and normal cerebrospinal fluid constituents. For a diagnosis of idiopathic intracranial hypertension (IIH), she was treated with acetazolamide and methylprednisolone, but vision worsened, so she underwent bilateral optic sheath fenestration (ONSF). Within the 1st postoperative week, vision had improved and papilledema was less prominent.
