Uso della monoterapia con Bimatoprost nella clinica quotidiana
2011
Gli Autori riportano i risultati di uno studio multicentrico,prospettico, osservazionale condotto nel 2010 sull'uso nella pratica clinica della monoterapia con l'analogo prostanidico ,Bimatoprost 0.3 mg/ml, in pazienti con glaucoma cronico ad angolo aperto mai trattati in precedenza se non con farmaci betabloccanti.
Cirugía no penetrante del glaucoma con espolonectomía. Valoración anatómica y funcional.
2016
INTRODUCCIÓN El glaucoma es una neuropatía óptica multifactorial que cursa con una pérdida progresiva de campo visual. La presión intraocular (PIO) es el factor de riesgo más importante y el parámetro modificable que mejor permite variar la evolución natural de la enfermedad. El tratamiento médico permite un control de la enfermedad en la mayoría de los casos, pero en ocasiones es necesario recurrir al tratamiento quirúrgico para producir descensos de la presión intraocular que eviten la progresión del daño. La trabeculectomía es el técnica quirúrgica de referencia, pero han ido apareciendo diferentes opciones con la finalidad de mantener los buenos resultados tensionales disminuyendo las c…
Visual Field defects, type A personality,anxiety and coping style in patients with primary open angle glaucoma.
2012
Classification of glaucomatous visual field defects for different severity levels is important. The reasons for this are numerous, and include: to distinguish between healthy and diseased individuals, to have homogeneous grouping criteria when perimetry is used to define the severity of glaucoma, to adjust therapy on the basis of disease severity, to describe visual field conditions in a short and simple format, to monitor the progression of the disease, and to provide a common language for both clinical and research purposes. Many severity classification methods have been proposed, although none have had widespread use in clinical practice. Other methods, like the cumulative defect curve (…
Plasmalogens in the pathogenesis of glaucomatous optic neuropathy
2011
Neuronal tissues such as the retina contain high amounts of plasmalogens. One of their particularities is to concentrate polyunsaturated fatty acids (PUFA) before releasing them specifically. Several data from our laboratory suggest that plasmalogens are involved in the pathophysiology of primary open angle glaucoma (POAG), the second leading cause of blindness worldwide. The different experiments were carried out on human patients with POAG as well as on rodent models of glaucoma. They concerned either the identification of specific alterations of plasmalogen metabolism, or the efficacy of PUFAs to prevent retinal damage. The results have shown a loss of several circulating plasmalogens in…

Characterization of cholesterol metabolism in an experimental model of glaucoma in rats
2019
International audience; Glaucoma is a neurodegenerative pathology characterized by retinal ganglion cell death. Cholesterol homeostasis disruption has been implicated in several neurodegenerative diseases such as Alzheimer and Huntington. However, its specific role in the retina and association with glaucoma remain unclear. The aim of this study was to characterize the modifications of cholesterol metabolism occurring during an experimental model of glaucoma in rats. Eight-weeks old male rats were subjected to laser photocoagulation of episcleral veins, limbus and trabecular meshwork to elevate intraocular pressure. At a short (3 days) and a long (2 months) time period post-laser, the retin…

Cholestérol-24S-hydroxylase (CYP46A1) et homéostasie du cholestérol dans la rétine en conditions physiologiques et pathologiques
2012
Cholesterol is the major sterol found in the retina. In its free form, cholesterol is present in all cell layers of the retina, whereas cholesteryl esters mainly accumulate at the basement of the retinal pigment epithelium. The intrinsic capacity of the retina to synthetize cholesterol appears limited. Some extra-retinal pathways actively participate to cholesterol uptake to the retina. Müller glial cells may contribute to cholesterol supply to retinal neurons, especially for synaptic formation. Cholesterol accumulation or conversely deficiency have deleterious consequences on neuron survival. Maintaining the equilibrium between cholesterol supply and neosynthesis in the one hand and choles…
