Abstract
We present the case of a 45-year-old male patient with sudden painless visual loss in the left eye (OS), diagnosed as nonarteritic anterior ischemic optic neuropathy (NAION). Three months later, a new superior scotoma, accompanied by an inferior optic disc edema, characterized a recurrent episode of NAION in OS. Ambulatory blood pressure monitoring disclosed arterial hypertension, with no pressure drop during sleep. Optical Coherence Tomography showed optic disc drusen. Ipsilateral recurrence of NAION is a rare event. We believe insufficient relief of the “crowding” effect in predisposed optic discs after a sectoral NAION episode is an important risk factor for ipsilateral recurrences.
