24S-hydroxycholesterol and cholesterol-24S-hydroxylase (CYP46A1) in the retina: from cholesterol homeostasis to pathophysiology of glaucoma.

2011

http://www.sciencedirect.com/; International audience; Free cholesterol is the predominant form of cholesterol in the neural retina. The vertebrate neural retina exhibits its own capacity to synthesize cholesterol and meets its demand also by taking it from the circulation. Defects in cholesterol synthesis and trafficking in the neural retina has detrimental consequences on its structure and function, highlighting the crucial importance of maintaining cholesterol homeostasis in the retina. Our purpose was to give a review on the functioning of the retina, the role of cholesterol and cholesterol metabolism therein, with special emphasis on cholesterol-24S-hydroxylase (CYP46A1). Similar to th…

The role of neuroinflammation in the pathogenesis of glaucoma neurodegeneration

2020

The chapter is a review enclosed in the volume "Glaucoma: A pancitopatia of the retina and beyond." No cure exists for glaucoma. Knowledge on the molecular and cellular alterations underlying glaucoma neurodegeneration (GL-ND) includes innovative and path-breaking research on neuroinflammation and neuroprotection. A series of events involving immune response (IR), oxidative stress and gene expression are occurring during the glaucoma course. Uveitic glaucoma (UG) is a prevalent acute/chronic complication, in the setting of chronic anterior chamber inflammation. Managing the disease requires a team approach to guarantee better results for eyes and vision. Advances in biomedicine/biotechnolog…

VisuMax®femtosecond laser for corneal refractive surgery

2008

Femtosecond lasers are increasingly present in ophthalmologic surgical theaters for a variety of reasons. These include faster and better visual outcomes, increased accuracy and predictability for corneal flap thickness in laser in situ keratomileusis procedures. Recent applications of modern femtosecond lasers have broadened the range of uses: keratoplasty, intrastromal segment insertion and even glaucoma and presbyopia surgery. This device profile provides an overview of the advantages of femtosecond lasers in ophthalmic surgery, paying special attention to the new VisuMax® femtosecond laser from Zeiss/Meditec.

Nuevos factores de riesgo para la progresión del Glaucoma

2015

INTRODUCCIÓN El Glaucoma es una neuropatía óptica de desarrollo progresivo que afecta a 90 millones de habitantes del planeta, siendo la forma clínica conocida como glaucoma primario de ángulo abierto (GPAA) la primera causa de ceguera irreversible en los países desarrollados. Los factores de riesgo para su desarrollo incluyen en primer lugar la presión intraocular, pero también la edad, la raza, la predisposición familiar, el espesor corneal central, miopía y presión de perfusión ocular han sido descritos como importantes en el desarrollo y/o progresión del glaucoma, entre otros. No obstante, hay evidencia acerca de la existencia de otros factores de riesgo, los denominados emergentes, así…

Correlación entre la expresión de microRNAs en hipertensión ocular versus glaucoma primario de ángulo abierto

2018

El Glaucoma Primario de Ángulo Abierto (GPAA), la primera causa mundial de ceguera irreversible, aumenta su prevalencia en mayores de 40 años. El primer factor de riesgo es la hipertensión ocular (HTO). No existe un biomarcador que pueda identificar sujetos con mayor predisposición hacia el GPAA. Planteamos la búsqueda de biomarcadores moleculares que ayuden a predecir el riesgo de padecer la enfermedad o de progresión de la misma. Las pequeñas moléculas de ARN no codificante (21-30 nucleótidos) que regulan la expresión génica a nivel posttranscripcional, se denominan miRNAs y se han relacionado con diversas patologías oculares. Esta Tesis Doctoral propone relacionar el perfil diferencial d…
