Nuevo instrumento para medir la sensibilidad al contraste sin y con deslumbramiento

C Sanchez Ramos; Mc Puell Marín; M.J. Perez Carrasco; A. Langa–Moraga; J.M. Benitez del Castillo

Objetivo/Metodo: Valorar la sensibilidad al contraste fotopica, sin y con deslumbramiento con un nuevo instrumento. Se estudiaron 78 ojos derechos de 49 adultos jovenes y de 29 adultos entre 35 y 55 anos. La sensibilidad al contraste se midio con el Contrast Glaretester CGT-1000 mediante una estrategia automatizada de reconocimiento para seis frecuencias espaciales. Resultados/Conclusiones: Los valores de sensibilidad al contraste fueron semejantes a los obtenidos con otros tests clinicos. El aumento de la edad disminuyo significativamente la sensibilidad al contraste sin y con deslumbramiento. Sin embargo, el deslumbramiento no modifico la sensibilidad al contraste fotopica.

Visual acuity of people over 55 years old in habitual corrective conditions: drivers versus non-drivers

Jj Navarro Valls; G Ramirez Mercado; E Gomez Tortuero; A. Langa–Moraga; C Sanchez Ramos

Purpose Our aim is to investigate the habitual VA in a non‐clinical population aged 55 years and over without evident pathology in order to estimate needs for best correction, comparing drivers’ and non‐drivers’ condition.
