Abstract
Introducción: La neuropatía óptica isquémica no arterítica (NOIANA) es la causa más frecuente de lesión aguda del
nervio óptico y la segunda causa de neuropatía óptica por detrás del glaucoma. Desarrollo: El perfil clínico de los pacientes
es de 50 años de edad y suelen presentar factores de riesgo cardiovascular. El cuadro típico consiste en una pérdida de visión
monocular indolora por un defecto en el campo visual con edema de papila. La NOIANA se produce por una alteración en la
perfusión en la cabeza del nervio óptico, en teoría debida a hipotensión nocturna y a una ratio excavación/papila pequeña. El
diagnóstico es esencialmente clínico y el pronóstico es incierto. Conclusión: A pesar de los numerosos intentos médicos y
quirúrgicos, no existe tratamiento eficaz. El objetivo de este artículo es hacer una revisión de la literatura y resumir los datos
actuales de los tratamientos propuestos. ---------------------
Introduction: Nonarteritic anterior ischemic optic neuropathy (NAION) is the most common cause of acute optic nerve injury is the second most common optic neuropathy after glaucoma. Development: Patients are over the age of 50 years with vascular risk factors. This condition typically presents with acute, painless, monocular loss of vision associated with a variable visual field defect and optic disc edema. NAION is produced by inadequate perfusion of the optic nerved head, supposedly because of nocturnal hypotension and small cup/disk ratio. Diagnosis is mainly clinical and prognosis is generally guarded. Conclusion: There is no treatment for this condition despite numerous medical and surgical attempts. This article reviews the literature and summarizes current data of proposed treatments.
