Makroaneurisme i retina

Metabolism of the retina. I. Respiration of cattle retina.

In view of the many interesting metabolic properties of the retina it is surprising to find that relatively few investigations on this subject have been reported. The retina is reputed to have high rates of respiration and glycolysis as well as a strong Pasteur effect (1). In this paper observations on the metabolism of the retina dealing with various aspects of respiration are reported. An att...

Autoimmunity and the retina. I. Antigenic specificity of photoreceptor cells.

IGF-I mRNA and signaling in the diabetic retina.

IGF-I promotes the survival of multiple cell types by activating the IGF-I receptor (IGF-IR), which signals downstream to a serine/threonine kinase termed Akt. Because in diabetes vascular and neural cells of the retina undergo accelerated apoptosis, we examined IGF-I synthesis and signaling in the human and rat diabetic retina. In retinas obtained postmortem from six donors aged 64 +/- 8 years...

Comparison of Neuroretinal Rim Area Measurements Made by the Heidelberg Retina Tomograph I and the Heidelberg Retina Tomograph II

PURPOSE To investigate the agreement between neuroretinal rim area (RA) measurements using the Heidelberg Retina Tomograph I (HRT Classic) and Heidelberg Retina Tomograph II (HRT II). To compare apparent RA changes in follow-up series of HRT II topographies when using either an HRT Classic or HRT II mean topography as baseline. DESIGN Cross-sectional study and "no-change," short time series s...

Gyrate Atrophy of the Choroid and Retina: A Case Report

Introduction Gyrate atrophy of the choroid and retina is a metabolic disorder, which is inherited in an autosomal recessive pattern. Although gyrate atrophy is rare, it is concerning as it results in blindness. It is characterized by hyperornithinemia, retinal atrophy, leads to progressive myopia and tunnel vision,...
