Abstract Background: Fluoxetine enhances the levels of brain-derived neurotrophic factor (BDNF); considering its known improving effects on neurogenesis and plasticity, it seems to improve the Anterior Ischemic Optic Neuropathy (AION). This study aimed to evaluate the effect of Fluoxetine on clinical prognosis of patients with AION.Methods: In this double-blind placebo-controlled randomized clinical trial, subjects with AION who were referred to Rasool Akram Hospital were divided into two study groups; the fluoxetine group that received 20 mg Fluoxetine daily(n=50) and the control group (n=50) that received placebo for a period of six months. Patients underwent clinical and paraclinical evaluations before and after the trial. This study was a registered trial with IRCT code IRCT20181109041596N1.Results: One hundred patients were enrolled from August 2019 to December 2020 and assessed in this study. Subjects in Fluoxetine group showed significant improvement in visual acuity in comparison to the placebo group with less score in LogMAR scale (P: 0.008 and 0.002, respectively), improvement in MD parameters of perimetry (P: 0.003 and 0.002, respectively), and decrease in VEP latencies (P (in 1st minute): <0.001 and <0.001, P (in 15st minute): 0.038 and 0.011, respectively). There were no differences in color vision, Rnfl in all dimensions, PSD parameter of perimetry or VEP amplitudes following the trial of Fluoxetine therapy (Ps> 0.05).Conclusion: Fluoxetine showed promising therapeutic value for patients with AION besides its safety as an additive treatment option to corticosteroids.

Nonarteritic anterior ischemic optic neuropathy (NAION) is the most common cause of acute vision loss in older people, and there is no effective therapy. The effect of the systemic or local application of steroids for NAION patients remains controversial. Oroxylin A (OA) (5,7-dihydroxy-6-methoxyflavone) is a bioactive flavonoid extracted from Scutellariae baicalensis Georgi. with various beneficial effects, including anti-inflammatory and neuroprotective effects. A previous study showed that OA promotes retinal ganglion cell (RGC) survival after optic nerve (ON) crush injury. The purpose of this research was to further explore the potential actions of OA in ischemic injury in an experimental anterior ischemic optic neuropathy (rAION) rat model induced by photothrombosis. Our results show that OA efficiently attenuated ischemic injury in rats by reducing optic disc edema, the apoptotic death of retinal ganglion cells, and the infiltration of inflammatory cells. Moreover, OA significantly ameliorated the pathologic changes of demyelination, modulated microglial polarization, and preserved visual function after rAION induction. OA activated nuclear factor E2 related factor (Nrf2) signaling and its downstream antioxidant enzymes NAD(P)H:quinone oxidoreductase (NQO-1) and heme oxygenase 1 (HO-1) in the retina. We demonstrated that OA activates Nrf2 signaling, protecting retinal ganglion cells from ischemic injury, in the rAION model and could potentially be used as a therapeutic approach in ischemic optic neuropathy.
