Introduction: Non-arteritic Ischemic Optic Neuropathy is the most common type of ischemic optic neuropathy. Nearly half NAION patients presented with 20/30 or better visual acuity. Central vision often preserved relative to field loss. Macular edema in patient rare, and its occurrence may confuse other disease lead unnecessary treatment.
 Case Report: We identified three macular edema. The...

purpose: to compare ipsilateral and contralateral carotid wall thickness in patients with acute unilateral non-arteritic anterior ischemic optic neuropathy (naion). methods: this prospective case series included 17 (10 male and 7 female) patients with unilateral naion of less than 8 weeks' duration who underwent b-mode ultrasonography to measure intima-media thickness (imt) in the common c...

A 53-year-old man was attended to the Clinic Ophthalmic Center, Mansoura University, Egypt, with recurrent transient monocular visual loss after receiving sildenafil citrate (Viagra) for erectile dysfunction. Examination for possible risk factors revealed mild hypercholesterolemia. Family history showed that his father had suffered from bilateral nonarteritic anterior ischemic optic neuropathy ...

We report a 64-year-old patient who developed nonarteritic ischemic optic neuropathy (NAION) in both eyes following cataract extraction. The cataract surgeries in both eyes were uneventful and performed within a year, and NAION occurred a few months postoperatively in both eyes. A review of the literature on this rare complication is provided. This case report serves to raise awareness among ca...

We present the case of a 45-year-old male patient with sudden painless visual loss in left eye (OS), diagnosed as nonarteritic anterior ischemic optic neuropathy (NAION). Three months later, new superior scotoma, accompanied by an inferior disc edema, characterized recurrent episode NAION OS. Ambulatory blood pressure monitoring disclosed arterial hypertension, no drop during sleep. Optical Coh...

WE REPORT THE FIRST CASE OF NONARTERITIC ANTERIOR ISCHEMIC NEUROPATHY (NAION) ASSOCIATED WITH DOUBLE THROMBOPHILIA: protein S deficiency and prothrombin G20210A mutation. A 58-year-old man is presented including the clinical and laboratory findings, cardiovascular profile and thrombophilia screening. The patient presented with 3/10 vision and an inferior altitudinal defect in the right eye. Fun...

Purpose. To describe a patient who developed bilateral, simultaneous nonarteritic anterior ischemic optic neuropathy (NAION) after ingestion of Sildenafil citrate (Viagra) for erectile dysfunction. Methods. Observational case report. Results. A 60-year-old diabetic man noted sudden decrease of vision in both eyes 16 hours after his third consecutive 50 mg daily Sildenafil ingestion. A diagnosis...

We report a case of simultaneous bilateral nonarteritic anterior ischemic optic neuropathy (NAION) due to sildenafil use. A 55-year-old man with an unremarkable medical history presented simultaneous bilateral NAION 8 months after continuous use of sildenafil 4-5 times a month. At presentation, visual acuity (VA) was 0.7 in the right eye (RE) and 0.9 in the left eye (LE). The visual field showe...

Aims: This study was aimed to investigate the association between angiotensin-converting enzyme gene (ACE) polymorphisms (rs4291, rs4309, rs4343, rs4646994) and nonarteritic anterior ischemic optic neuropathy (NAION) risk. Methods: The method of polymerase chain reaction (PCR) was used to perform the genotyping of ACE polymorphisms between the case and control groups. The χ2 test was conduct to...

PURPOSE To describe a case of non-arteritic ischemic optic neuropathy (NAION) secondary to acute primary-angle closure (APAC). METHODS Case report. RESULTS A 50-year-old woman with painful visual loss in the right eye was found to be in APAC with a right afferent pupillary defect. Laser peripheral iridotomy relieved pain but did not improve vision. Diffuse optic disc edema in the right eye ...
