[Semi-automated quantification of MRI high signals observed in multiple sclerosis].

MR T2 Weighted sequences on the brain demonstrate disseminated "high signal zones" (HSZ) in patients with Multiple Sclerosis; these morphological alterations are corresponding to the plaques. From the very beginnings of MR in 1981, everybody recognizes the main importance of this fact. MR appears as the most sensible exploration in patients with M.S. But the signal alteration is not specific; the clinical considerations and the evolution are requested. The aim of this work is to give a reference tool for evolutive evaluation of the disease. A work station with a specially developed software are presented. The HSZ thresholding is partially automatic. The edition of a cerebral mapping is developed. These results are discussed.

[Oculomotor paralysis of endocrine origin. The value of x-ray scanning].

The X-ray scanning symptoms of dysthyroidal ophtalmopathy are so typical that they are enough to make the diagnosis in most of cases. Their determination through the FEMEN system increases the sensitivity of the method. The investigation of 60 cases of oculomotor palsies with a FEMEN score greater than 10 confirms that they are certainly or probably subsequent to an endocrinopathy in 93% ot the cases.

[Persistent and hyperplastic primary vitreous syndrome. Clinical and therapeutic aspects].

PURPOSE: Persistent hyperplastic primary vitreous (PHPV) is a rare developmental malformation of the eye. This anomaly is usually unilateral and unassociated with other disease. PHPV may have clinical variations: an anterior and/or a posterior one. Diagnosis and treatment are exposed in our paper. METHODS: We study 38 eyes in 34 patients. All patients had an anterior form of PHPV. Nine of them associated a posterior form. Eighteen eyes underwent surgery, the mean postoperative follow-up is 4.7 years. Treatment is discussed, depending on the initial form of PHPV. We report the evolution of the surgical eyes and the untreated eyes. RESULTS: Slit lamp examination and echographic findings (A-scan and B-scan) support the diagnosis. In some cases computed tomography or RMN can be useful. If the cataract is mild in the anterior form of PHPV, treatment of amblyopia and frequent clinical examination can be sufficient. If the cataract is dense, a lensectomy must to be performed. The surgical technique can be difficult. For the eyes with posterior PHPV, the surgical treatment is to be avoided, because of high risk of retinal detachment. CONCLUSION: PHPV may have clinical variations, mostly with cataract as major sign. In purely anterior presentation, in absence of marked microphthalmos, lensectomy can be useful.
