Review of evidence for treatments of acute non arteritic anterior ischemic optic neuropathy

Abstract

Objective: To review treatment modalities that have been studied in acute non arteritic anterior ischemic optic neuropathy (NAION).

Methods: We performed a comprehensive literature search of English language publications in the last 5 years, with human species and NAION. Articles were reviewed to identify those that described original research on treatment of acute NAION. Study type, setting, duration, interventions, and results were extracted and articles were reviewed for biases and limitations.

Results: We identified 22 kinds of treatment varying by compound and modality. These include topical, intravitreal, and systemic drugs as well as surgical approaches. Evidence for efficacy ranges from expert opinion to randomized control trials.

Conclusions: Although several treatments are utilized in practice, none of these have high quality evidence of efficacy to improve visual outcomes. Continued collaborative research is necessary to complete high quality studies in order identify effective therapies for this rare and blinding disease.
