Time course of IOP elevation, electroretinographic changes and retinal ganglion cell loss in a rat model of glaucoma induced by laser
2007
International audience; Purpose: To evaluate the time course of intraocular pressure (IOP) elevation, electroretinographic changes and retinal ganglion cell (RGC) loss in a rat model of glaucoma induced by photocoagulation of the trabeculum and the episcleral and limbal veins. Methods: Male Sprague Dawley rats were used at 6 weeks of age. At least 3 of the episcleral veins, the trabeculum and the limbal veins were photocoagulated with a laser at 532nm (Quantel Medical, Vitra) in one eye of the animals. IOP and electroretinogram (ERG) were monitored every 2 weeks during 11 weeks after photocoagulation. Three months after laser photocoagulation, the RGC population was identified with a 5% Flu…
Metabolomic changes in the rat retina after optic nerve crush.
2013
Purpose To identify metabolic pathways and metabolites affected by optic nerve crush that can act as predictors of the disease or therapeutic targets. Methods The left optic nerve of adult rats was intraorbitally crushed and retinas were dissected 24 hours or 14 days after the lesion (n = 10 per group). Metabolic profiling analysis was carried out by Metabolon, Inc. A total of 195 metabolites were unambiguously detected. Data were normalized and the regulated metabolites were identified after comparing the different conditions. Metabolite concentration changes were analyzed using single and multivariate statistical analysis to detect discriminatory metabolites. Functional clustering and met…

Purpose To test the efficacy of dietary omega-3 and omega-6 fatty acids in a rat model of glaucoma induced by laser photocoagulation. Methods Rats were fed for 3 months with a diet containing either: 1) 17% of omega-3 fatty acids (10% EPA + 7% DHA), 2) 10% of omega-6 fatty acids (as GLA), or 3) a combination of both omega-3 and omega-6 fatty acids (10% EPA + 7% DHA + 10% GLA), by comparison with a control group of animals fed with a standard diet deprived of EPA, DHA and GLA. After 3 months of diet, glaucoma was induced in one eye of the animal by laser.IOP was regularly measured and the retinal function was evaluated by electroretinography (ERG) for 3 months. At the end of the experiment, …
