What is orbital pseudotumor?

We have reviewed the literature in order to delineate the clinicopathologic definition of orbital pseudotumor, also called idiopathic nonspecific orbital inflammation. The clinical picture of orbital pseudotumor varies widely, with signs of mass effect, inflammation and/or infiltration. On computed tomography, orbital pseudotumor presents as a unilateral focal or diffuse mass.

Localized hypertrichosis associated with periorbital neurofibroma: clinical findings and differential diagnosis.

Background: Congenital localized hypertrichosis in the periorbital region is an uncommon finding. The authors report two patients with hypertrichosis and cutaneous hyperpigmentation overlying a periorbital neurofibroma.

Methods: In addition to a complete ophthalmic and systemic examination, the patients underwent computed tomography of the head and biopsy of the tumor.

Orbital decompression for Graves' ophthalmopathy by inferomedial, by inferomedial plus lateral, and by coronal approach.

To test the efficacy and safety of orbital decompression for Graves' ophthalmopathy, the authors studied the records of 60 consecutive patients who were operated on for dysthyroid optic neuropathy or for rehabilitative purposes. Patients decompressed for neuropathy were older, had less proptosis, and a shorter duration of eye disease than patients operated on for disfigurement. The authors compared the results of three surgical procedures including the inferomedial, the inferomedial plus lateral, and the coronal approach.

Primary versus secondary intraorbital implants.

To compare the results of primary and secondary intraorbital implants after enucleation, we retrospectively studied the surgical outcomes of 114 patients. In 44 patients the implant was inserted immediately after enucleation and in the remaining 70 patients the implant was inserted at a later date. To achieve a satisfactory cosmetic result, additional procedures were needed in 11% of the patients with a primary implant and in 49% of those with a secondary implant.

Eyelid and orbital fascial attachments and their clinical significance.

Orbital connective tissue can be considered as an additional locomotory system of the eye. It is involved in orbital fractures, explaining the bizarre motility patterns in these patients. Various conditions, in patients with Graves' disease, are explained using the orbital connective tissue system as a key-stone.
