To explore the best method for diagnosis and treatments of post-surgical posterior ischemic optic neuropathy(PION). MethodsReview the medical records of a 78-year-old female patient who presented with sudden vision loss in her right eye on the fourth day after phacoemulsification and implantation of a posterior chamber intraocular lens in other hospital. After the electrophysiological examination and fundus fluorescein angiography, the patient was diagnosed as posterior ischemic optic neuropathy after cataract surgery in his right eye. She was administered with a retrobulbar injection of Anisodamine and placed on steroid pulse therapy. ResultsOn the 19th day after treatment, her visual acuity had recovered to 0.05. ConclusionThis is a rare case, and since post-surgical posterior ischemic optic neuropathy(PION)has no definite and effective treatment yet, active vigilance should be maintained before surgery. Detailed systemic history and physical examination are important for patients with high risks of developing PION, especially for evaluating their systemic hemodynamics. To sum up, PION should be considered in patients who have sudden severe vision loss and/or visual field defects with no obvious changes in the fundus after excluding other optic nerve diseases.
