Amaurosis fugaz - Symptom

Nombres alternativos

Ceguera monocular transitoria

Síntomas:

Entre los síntomas se incluye la pérdida súbita de la visión en uno de los ojos. Esto generalmente dura segundos, pero puede durar algunos minutos. Algunos pacientes describen esta pérdida de la visión como una sombra gris o negra que baja por los ojos.

Signos y exámenes:

Los exámenes incluyen una evaluación oftalmológica y neurológica completa. En algunos casos, un examen ocular revelará un punto brillante donde el coágulo está bloqueando la arteria retiniana. Se debe realizar una ecografía de la carótida o una angiografía por resonancia magnética (ARM) para evaluar una obstrucción de dicha arteria carótida.

También se deben hacer exámenes de sangre rutinarios como el de colesterol y el de glucemia (glucosa) para verificar el riesgo de ateroesclerosis, el cual aumenta con el colesterol alto y la diabetes.
