Pigmentary Uveitis

The recent report by Townsend and Gornik aims to provide more reliable data on the prevalence of two common but poorly understood ocular conditions of Golden Retrievers: uveal cysts and pigmentary uveitis (PU). The study is well designed in terms of patient selection and examination methods, and high degree of disease ascertainment and diagnostic consistency was obtained by having all examinations performed by a single board-certified veterinary ophthalmologist. Even though this and two other studies suggest that these two conditions may perhaps be part of a broader disease complex, there is, as yet, no conclusive evidence of such an association

Window Into Retinal Studies

Professor Gustavo Aguirre discusses the context of his research studies at the University of Pennsylvania, which are currently concentrating on the degenerative disease, retinitis pigmentosa

Concepts and Strategies in Retinal Gene Therapy

Genetic defects of the retina or retinal pigment epithelium (RPE) cause a substantial number of sight-impairing or blinding disorders, many of which eventually cause the degeneration and death of the visual cells. Previously considered incurable, some of these retinal diseases can now be treated, at least experimentally, by gene therapy

La audiovisión como semiosis de la imagen-sonido

Este trabajo se orienta hacia el análisis del producto audiovisual e indaga la obra como un modo de representación de la extimidad. La relación entre el sonido y la imagen es una parte esencial de una película y, en el presente apartado, se expondrán distintos conceptos que describen esta interacción. A pesar de la importancia del sonido, siempre se omite de los análisis y del recuento de la experiencia cinematográfica, con la excepción de la música

The Briard Problem

The Briard breed has stimulated some ophthalmic interest in Canada, Europe, and the United States. Ophthalmoscopic changes similar to central progressive retinal atrophy have been diagnosed. This report adds further insight into the type of retinal degeneration and questions the associated physical findings as they may relate to the retinal disease
