Objective: To investigate of clinical and demographic characteristics of patients with non-arteritic anterior ischemic optic neuropathy (NA-AION). Material and Methods: The data of 229 patients with NA-AION who applied to the Department of Neuro-ophthalmology of Ulucanlar Eye Hospital between 2006-2017 were evaluated, retrospectively. Age of onset of the disease, gender, laterality, co-existing systemic diseases, medical treatments, follow-up period, the best corrected visual acuities (BCVA) at the first and final visit, type of the visual field loss, ocular risk factors were recorded. Results: The study included 245 eyes of 229 patients. The study group consisted of 98 (42.8%) female, 131 (57.2%) male. The second eye involved in 34 (14.8%) of the patients. The medium age of onset of the disease was 59.7±9.6 years, the median follow-up period was 8 (4-132) months. The NAION is onset under 50 years in 43 (18.7%) of all patients. There was statistically significant increase in BCVA at the final visit when compared to baseline. The most common systemic diseases were diabetes mellitus (20.8%) and hypertension (13.5%). In young patients without systemic disease, ocular risk factors were more prominent and outcome of BCVA was better than older ages at the final visit. During the follow-up period, no medication was given in 42 (17.1%), aspirin in 141 (57.5%) oral or intravenous steroids in 16 (6.5%) eyes. The eyes treated with brimonidine and/or coenzyme Q10 as topical treatment were 66 (26.9%). There was no statistically significant difference between treatment modalities for each treatment groups at the final visit. Conclusion: Diabetes Mellitus and hypertension are the most important risk factors in NA-AION, which causes permanent loss of visual acuity in the middle and older ages, while ocular risk factors are in the younger ages. Also, younger patients have better final visual acuity.
