Retina Thinning Linked to Parkinson’s Disease: Potential Diagnosis via Optical Coherence Tomography (2024 Study)

by

Optical coherence tomography (OCT) reveals significant retinal nerve fiber layer (RNFL) thinning in Parkinson’s disease (PD) patients, correlating with disease severity and suggesting OCT as a potential biomarker for PD diagnosis and monitoring. Highlights: RNFL Thinning: Parkinson’s disease patients exhibit significant thinning of the retinal nerve fiber layer (RNFL) compared to non-PD individuals (p = …

Eye Retinas as Biomarker for Suicide Risk: Potential of Electroretinography (ERG) in Detection

by

Electroretinography, a non-invasive retinal scanning technique, shows some promise for detecting suicidal behaviors based on changes in retinal cell signals. However, large scale studies are needed to determine its reliability. Key Facts: Electroretinography (ERG) measures electrical signals from retinal cells in response to light flashes to assess retinal health. ERG wave changes have been linked …
