[Clinical signs of dysthyroid orbitopathy].

Dysthyroid ophthalmopathy is an inflammatory disease of the orbit, combined or not with thyroid disorders. However, pure ophthalmologic forms exist, and the diagnosis can be made by the ophthalmologist. The diagnosis is made by examining eyelid malposition, oculomotor disorders, inflammatory signs, proptosis measurement, and by the search for optic nerve pain. We discuss the NOSPECS classification, which can evaluate the severity and progression of the disease.

[Complications of dysthyroid ophthalmopathy].

The complications of dysthyroid ophthalmopathy should be known and screened in every patient since they can worsen visual prognosis and are critical to the decision for treatment. Ocular surface alteration can result from eyelid malposition, blinking deficiency, eye dryness, and proptosis. Oculomotor disorders are detected by coordimetry or a forced duction test. Optic neuropathy can be compressive or glaucomatous. Intraocular pressure elevation can result from elevation of intraorbital pressure, indentation by an enlarged muscle, or increased backflow in episcleral veins.

[Orbital fat decompression techniques].

Fat removal orbital decompression (FROD) was first described by Olivari in 1988. Through a blepharoplasty approach, fat pads from the five palpebral pockets, as well as intraconal fat, are carefully removed. The main complications are retrobulbar hemorrhage and postoperative diplopia. The best indications are patients with wide orbits without compressive optic neuropathy. FROD is an inescapable procedure in a balanced approach to surgical orbital decompression.

Bone formation in hydroxyapatite tricalcium phosphate ceramic implants used in the treatment of the postenucleation socket syndrome.

PURPOSE: To determine the histopathologic changes in coralline hydroxyapatite tricalcium phosphate (HA-TCP) blocks used in the treatment of the postenucleation socket syndrome (PESS). METHODS: Twenty-four patients were treated with HA-TCP blocks placed directly into the orbital fat to correct the PESS. Eight of these patients required partial removal of the material for various reasons between 32 and 371 days after the initial operation. The orbital implants were decalcified and processed for light and electron microscopic examination. RESULTS: Light microscopy demonstrated fibrovascular ingrowth into the pores of the implant in all cases. Osteogenesis was observed in three cases in the periphery of the implant. Ossification occurred in the implants after a mean implantation duration of 276 days versus 67 days in cases without ossification. CONCLUSION: Implants of HA-TCP, a new material used in ophthalmology, demonstrate the presence of fibrovascular ingrowth, reflecting the excellent biointegration of this material.
