Un estudio reciente publicado en “Ophthalmology” señala que la mala visión nocturna podría predecir la degeneración macular asociada a la edad (DMAE).
Más de mil personas que mostraban signos precoces de DMAE recibieron un cuestionario de diez preguntas donde se les pedía clasificar sus dificultades con la conducción nocturna y con las actividades en penumbra, como leer o ver cine, y se les hizo seguimiento anual durante seis años. Los que tenían la peor visión nocturna al inicio tuvieron más probabilidades de desarrollar menor agudeza visual y uno de dos tipos de DMAE avanzada, la atrofia geográfica o la neovascularización coroidal (NVC).
Gui-shuang Ying, autor principal del estudio, de la Universidad de Pensilvania (Estados Unidos), asegura que este cuestionario simple podría resultar útil para identificar a los pacientes en alto riesgo de pérdida de visión y DMAE avanzada.
