The Exorbital Lacrimal Gland Is 100 Times More Susceptible Than the Retina to Dietary Supplies in Long Chain Omega-6 and Omega 3 Polyunsaturated Fatt…
2007
International audience; Purpose:: The purpose of this study was to compare the susceptibility of the retina and the exorbital lacrimal gland to dietary supplies in long chain omega-3 (ω3) and omega-6 (ω6) polyunsaturated fatty acids (LC-PUFAs). Methods:: Male Wistar rats were fed for 3 months with a 5% lipid-diet containing either: 1) 10% of EicosaPentaenoic Acid (EPA, ω3) and 7% of DocosaHexaenoic Acid (DHA, ω3), 2) 10% of γ-Linolenic Acid (GLA, ω6), 3) 10% of EPA, 7% of DHA and 10% of GLA or 4) a balanced diet deprived from EPA, DHA and GLA. After three months of feeding, lipids were extracted from the retina and the exorbital lacrimal gland and fatty acid composition was determined by ga…
No consequence of dietary omega-3 polyunsaturated fatty acid deficiency on the severity of scopolamine-induced dry eye
2008
International audience; Purpose:Epidemiological studies suggest that dietary omega-3 polyunsaturated fatty acids (PUFAs) may protect against prevalence of dry eye. This work aimed to evaluate whether a dietary deficiency in omega-3 PUFAs may increase the severity of dry eye in a scopolamine-induced rat model. Methods:Three consecutive generations of Lewis rats were bred under diets deprived of omega-3 PUFAs. Dry eye was experimentally induced by continuous scopolamine delivery in female animals from the third deficient generation and in female Lewis rats fed for three generations with a balanced diet. After 14 days of treatment, the clinical signs of ocular dryness were evaluated in vivo us…
CT and MR Imaging of Orbital Lesions
1989
In the past, the diagnosis of orbital lesions manifested clinically by unilateral or bilateral proptosis and/or impaired ocular motility has relied on conventional skull films and orbital radiographs, sonography, fluorescein angiography, internal and external carotid angiography, and ophthalmic venography. The introduction of CT, however, has greatly reduced the importance of invasive diagnostic procedures (Wende et al. 1977).
