Evolution of Oculomotor Nerve Paresis after Endovascular Coiling of Posterior Communicating Artery Aneurysms: A Neuro-ophthalmological Perspective

Abstract

Although mass effect remains after endovascular packing, oculomotor nerve dysfunction improves comparably to the recovery observed after surgical clipping. Contrary to previous reports, typical residual oculomotor nerve deficits persist. Older age and the presence of microvascular risk factors seem to be detrimental to ONP recovery.
