Abstract
Background: This study was conducted to review the demographic and clinical characteristics, treatment protocols, and visual outcomes of patients with optic neuropathy.
Methods: This historical cohort study analyzed the clinical features of 91 patients with optic neuropathy followed up for three years at a university hospital in Turkey.
Results: Non-arteritic anterior ischemic optic neuropathy (NA-AION) was the most common group among the optic neuropathy subgroups (47.2%), and optic neuritis (ON) was the second most common group (38.5%). The mean age of symptom onset for NA-AION was 64.97 ± 12.15 years, significantly higher than the mean age of onset for ON (40.28 ± 15.52 years). Most of the patients with NA-AION had at least one systemic disease causing microangiopathy [51.1% had diabetes mellitus (DM), 33.3% had hypertension (HTN)]. Among the patients with ON, 51.4% were idiopathic, and 25.7% were multiple sclerosis (MS)-related ON cases. Patients with ischemic optic neuropathy (ION), ON, and traumatic optic neuropathy received pulse intravenous (IV) corticosteroids, and eleven patients with NA-AION received acetylsalicylic acid (ASA) therapy in addition to corticosteroids. There was a statistically significant increase in visual acuity in NA-AION and ON groups (P = 0.019). It was observed that the cases of ON peaked in the winter months in Turkey.
Conclusion: In the differential diagnosis between NA-AION and idiopathic ON, the presence of one or more vascular systemic diseases and mean age may be the main factors. IV steroid treatment given to patients with NA-AION in the acute phase may significantly improve visual acuity.
