Retinal Docosahexaenoic Acid Is Significantly Reduced in Diabetic Humans and Mice: Possible Relationship to Diabetic Retinopathy.

Purpose: The retina contains the highest concentration of the omega 3 fatty acid, docosahexaenoic acid (DHA), in the body. Although epidemiologic studies showed an inverse correlation between the consumption of omega 3 fatty acids and the prevalence of diabetic retinopathy, there are no data showing the effect of diabetes on retinal DHA in humans. In this study, we measured the DHA content of the retina in diabetic and non-diabetic humans as well as mice and determined the effect of diabetes on retinal thickness and function in mice.

Pre-Service Predictors of New-Onset Alcohol Misuse in Male United States Marines.

Introduction: U.S. military personnel have a high prevalence of alcohol misuse, which can adversely affect force readiness.

A chart-based test of contrast sensitivity in noise: reference ranges, effects of age and optical abnormality.

Clinical Relevance: Contrast sensitivity plays an important role in the comprehensive assessment of visual function; however, measurement with standard eye charts can be affected by age and optical abnormality.

Background: This study describes a novel chart-based test of letter contrast sensitivity (CS) in luminance noise (the Illinois Eye and Ear Noise CS test), defines normal reference ranges, estimates test-retest repeatability, and assesses the effects of age and simulated optical abnormalities.

Methods: Seventy-five individuals with normal visual function (age 18-85 years) participated.

ISCEV standard for clinical pattern electroretinography (2024 update).

The pattern electroretinogram (PERG) is a localized retinal response evoked by a contrast-reversing pattern, usually a black and white checkerboard, which provides information about macular and retinal ganglion cell function.
