A woman in her 50s presented with diminution of vision in her left eye (OS) 4 days after COVISHIELD vaccination. She had been diagnosed with non-arteritic anterior ischaemic optic neuropathy (NA-AION) of right eye (OD) 8 months earlier. The present episode revealed a best-corrected visual acuity (BCVA) of 20/50 in OD and 20/20 in OS with grade 1 relative afferent pupillary defect. Fundus evaluation showed pale disc in OD and temporal disc oedema in OS. Humphrey's visual field analysis showed incomplete inferior altitudinal defect in OD and a centro-caecal scotoma in OS. Systemic investigations were normal. OS was diagnosed with NA-AION. She was started on oral aspirin 75 mg. At 1-month follow-up, disc oedema of OS had resolved with BCVA maintaining at 20/20. The patient was lost to follow-up later. The relationship between the vaccine and the ocular event is temporal with no causal association.

Clinical, laboratory, and orbital imaging features of giant cell arteritis in comparison to non-arteritic anterior ischemic optic neuropath: a single center case series.

Background: Giant cell arteritis (GCA) is the most common vasculitis in patients older than 50 years and is considered a "do not miss" diagnosis. However, it remains a diagnostic challenge given overlapping clinical syndromes such as non-arteritic anterior ischemic optic neuropathy (NAION) and poorly explored imaging findings.
Materials And Methods: In this retrospective study between the time period of January 2013 and December 2021, a total of 13 consecutive patients with a pathological diagnosis of GCA and 8 patients with clinical diagnosis of NAION were isolated.

Purpose: To assess the potential influence of serum biochemical factors, specifically lipid profile parameters, on visual outcomes in patients with non-arteritic anterior ischemic optic neuropathy (NAION).
Patients And Methods: All patients diagnosed with NAION at Rajavithi Hospital between 1 January 2011 and 31 December 2020 were retrospectively reviewed. The primary outcome was defined as visual recovery, measured by an improvement of at least 0.

Background: Differentiating arteritic anterior ischaemic optic neuropathy (A-AION) due to giant cell arteritis (GCA) from non-arteritic anterior ischaemic optic neuropathy (NA-AION) may pose a diagnostic challenge. Our study aimed to assess the use of standard orbital MRI in distinguishing ocular manifestations of GCA from NA-AION.
Methods: This study included 25 consecutive patients (11 GCA, 14 NA-AION) who underwent contrast-enhanced orbital MRIs within 3 months of symptom onset.
