El control y el cuidado de la presión arterial ayudan a reducir la pérdida visual por retinopatía diabética e hipertensiva, de acuerdo con varios estudios científicos (medicina basada en la evidencia).
Por otra parte, la hipertensión es una posible causa del glaucoma y de la degeneración macular relacionada con la edad. Así, lo han publicado especialistas de la University of Melbourne (Australia) en “The Lancet”.
La retinopatía hipertensiva se refiere a los signos de microvasculares dados en la retina que se desarrollan en respuesta al aumento de la presión sanguínea, sobre todo en mayores de 40 años y que son una llamada de atención para la presencia de derrames cerebrales y de enfermedades cardiovasculares.
Asimismo, la hipertensión es un factor de riesgo muy importante para el desarrollo de otras patologías vasculares retinianas, como las oclusiones de las venas y arterias de la retina y la neuropatía óptica isquémica.
La presión arterial alta aumenta el riesgo de presentar también diabetes y, por tanto, retinopatía diabética.
