[OCT-3 documentation of spontaneous resolution of blunt macular hole injury: a case study]. / Documentation par OCT-3 de la résolution spontanée d'un trou maculaire post-traumatique.

OBJECTIVE: To report a case of a spontaneous resolution of a macular hole resulting from injury. OBSERVATION: A 17-year-old man experienced a blunt injury: fundus examination found a full-thickness macular hole. It was studied with a clinical exam and optical coherence tomography images. After two weeks, the macular hole spontaneously disappeared. DISCUSSION: Blunt injury is the most frequent ocular injury. The consequences can be very serious because of possible lesions in the macular area: the visual function prognosis can therefore be disastrous. Macular holes can have a good prognosis, and spontaneous closure is sometimes observed. This report attempts to explain the mechanisms. CONCLUSION: Disappearance of a macular hole resulting from injury can occur spontaneously, especially in young patients. OCT is today indispensable, making it possible to follow up the injury and its consequences objectively, reliably and with very good reproducibility.

[Graves'ophthalmopathy: usefulness of T2 weighted muscle signal intensity]. / IRM et ophtalmopathies associées aux maladies thyroïdiennes: intérêt de l'analyse du signal des muscles oculomoteurs en T2.

OBJECTIVE: Immunosuppressive treatments may be usefull when Graves' ophthalmopathy is active. We evaluated the interest of hypertrophied muscle T2 weighted signal intensity as an argument of disease activity, to help for the therapeutic decision. PATIENTS AND METHODS: 46 MRI in 37 patients with Graves' ophthalmopathy were retrospectively studied. RESULTS: During the active phase of the disease, centro-muscular hypersignal was always observed (6 cases); signal intensity was not so bright or even disappeared with immunosuppressive treatment (7 cases). We never observed hypersignal when the disease was inactive (4 cases). When there was no hypersignal on T2 weighted images, the disease was inactive in 70% cases, and of low activity in the other cases. CONCLUSION: T2 weighted centro-muscular signal intensity analyse helps for the therapeutic decision in Graves' ophthalmopathy.
