[Intraorbital pressure measured before, during, and after surgical decompression in Graves' orbitopathy].

Purpose: In Graves' orbitopathy, the volumetric increase of the oculomotor muscles and orbital fat leads to exophthalmia and a rise in orbital pressure. This rise in pressure may be implicated in the appearance of a compressive optic neuropathy. To investigate this increase in pressure and its variations accompanying surgical decompression, systematic measurements were taken before, during, and after every case of orbital decompression in Graves' disease.

[Understanding refraction disorders and oculomotor problems during pregnancy].

During pregnancy, hormonal and hemodynamic modifications can generate a number of organic consequences, specifically ocular, more or less regressive in systemic disease. Refraction disorders are marked by myopization, often not very significant and always regressive within six weeks after the childbirth. Pregnancy could cause a thickening of the cornea and a modification of its curvature.

Unilateral retinal pigment epithelium dysgenesis.

Purpose: To report additional data on a pattern of the fundus described in 2002 as unilateral, idiopathic leopard-spot lesion of the retinal pigment epithelium (RPE).

Design: Observational, consecutive case series.

Methods: The fundus characteristics, natural history, and prognosis of 9 patients are described after examining them by means of diagnostic adjuncts not previously available, including optical coherence tomography (OCT) and fundus autofluorescence (FAF) photographs.

[Conjunctival Kaposi sarcoma].

Kaposi sarcoma is rare and occurs in four forms (classic, endemic, post-transplant and epidemic), which all have the same histological appearance associated with the same viral agent: human herpes virus type 8 (HHV-8). Conjunctival and palpebral locations are, however, rare, and only 30 cases have been described in the literature. We present the case of a 34-year-old woman with conjunctival Kaposi angiosarcoma, with rare bulbar location associated with superior palpebral telangiectases against a rare immunodepression syndrome (common variable immunodeficiency).

[Surgical treatment of diffuse adult orbital lymphangioma: two case studies].

Purpose: Orbital lymphangioma is a rare vascular malformation; it is a benign but severe anomaly because of its infiltrative, diffuse, and hemorrhagic nature, and its high morbidity rate. Surgical resection is a real challenge on account of the intricate architecture of the lesion. The authors report their surgical experience concerning two cases of diffuse orbital lymphangioma whose diagnosis was established in adulthood and whose surgical treatment was successful.
