T7. ELECTRORETINOGRAPHY FOR MAJOR PSYCHIATRIC DISORDERS IN MULTICENTRIC SITES

摘要

The retinal response to light assessed by electroretinography (ERG) has been recognized as a promising site of investigation for psychiatric disorders. Indeed, ERG anomalies were reported in major depression, schizophrenia and offspring of patients (1,2,3). Traditionally, it is performed with bulky equipment using a corneal electrode which may cause some discomfort. Recently an ambulatory portable device was proposed (RETeval; LKC Gaithersburg MD) along with a novel skin electrode allowing ambulatory non-invasive recordings to be performed anywhere. This device was recently introduced in the Lausanne-Geneva High Risk Cohort (4).
