In adults, optic neuritis (ON) is the most common clinical manifestation. MOGAD-ON can severely affect visual acuity (VA) and cause visual field (VF) deficits. VA typically improves rapidly with treatment, but little is known about VFs at follow-up. To address this, we analyzed VFs in MOG-ON patients. We conducted a multicentre international retrospective review of MOGAD-ON patients. VFs were obtained at presentation and follow-up at least 3 months later and before the next relapse. VF severity was based on the mean deviation (MD) measurements graded as mild, moderate, or severe. Specific VF deficit patterns and shapes were assessed by a single-blinded neuro-ophthalmologist (as per Optic-Neuritis-Treatment-Trial Group). Time to treatment was also assessed. Thirty-nine eyes of 28 patients were included (mean age 39.68 ± 12.9 years, 13 males). The average MD nadir from all 39 affected eyes was -14.18 (±9.8 dB) and -3.02 (±3.2 dB) at follow-up. At follow-up, 46% of the eyes developed permanent VF deficits with an MD below -2 dB. (41% with a recognizable VF deficit pattern) despite recovery to an average VA of 6/6.

Despite advancements in treatment, predicting long-term visual outcomes of MON remain challenging. The current study aimed to assess the potential association between arterial blood gas parameters and long-term changes of retinal nerve fiber layer (RNFL) in survivors of acute methanol poisoning. This prospective study was conducted on patients hospitalized with diagnosis of acute methanol poisoning at Ali Asghar Hospital, Shiraz, Iran, between 27 June 2020 and 12 August 2021 in COVID-19 era. The treatment included acid-base correction, hemodialysis, ethanol administration, erythropoietin, corticosteroids, and vitamin supplementation. Clinical and laboratory as well as comprehensive ophthalmologic examinations and high-definition optical coherence tomography (OCT) were performed at admission and after a 12-month follow-up to evaluate RNFL thickness and visual acuity (VA) alternations. A total of 61 patients (mean age: 30.08 ± 5.20 years; 91.8% male) with methanol poisoning were included in the study. Optic disc swelling was noted in 29 patients (47.54%), while 32 (52.46%) had normal optic discs. Most patients presented on Day 2 (34.43%) and Day 1 (32.79%) post-poisoning. Arterial blood gas analysis revealed a median pH of 7.0 (IQR: 6.85-7.28), bicarbonate levels of 17.0 mmol/L (IQR: 13.0-23.0), and an anion gap of 12.0 mmol/L (IQR: 9.0-15.0).
