We present a case of non-arteritic anterior ischaemic optic neuropathy (NAION) with no ocular or systemic risk factors in a patient who recovered from a recent SARS-CoV-2 pneumonia. NAION is the most common acute optic neuropathy among individuals over 50 years of age. It results from a transient hypoperfusion of the optic nerve head circulation, especially in patients with low vascular compliance due to ocular or systemic risk factors. We attribute the ophthalmological condition to a SARS-CoV-2 virus-associated endotheliopathy that can be prevented with timely protection of endothelial function with vitamins D and K2.

Anterior Ischaemic Optic Neuropathy

Background/AimsThe aim of this study was to identify specific MRI characteristics of anterior ischaemic optic neuropathy (AION) and optic neuritis (ON) that would aid in the differentiation between these two diagnoses.MethodsWe retrospectively analysed a consecutive case series including all patients with an MRI study of brain and orbit and the clinical diagnosis of either ON or AION. We examined the scans for restricted diffusion of the optic nerve, optic sheath diameter, enhancement and location of enhancement of the optic nerve and distribution of the white matter lesions.ResultsFifty patients met the inclusion criteria. We found an accuracy of 0.98 for the discrimination between AION and ON based solely on parameters extracted from MRI data. Dominance analysis to determine the most influential parameters showed that the enhancement pattern of the optic nerve and distribution of the white matter lesions had the biggest impact on the classification and led to a discrimination accuracy of 0.9 when used alone.ConclusionIn patients with an inconclusive clinical diagnosis, optic nerve enhancement pattern and distribution of white matter lesions can aid in the diagnosis and differentiation between AION and ON. Diffusion-weighted imaging did not add significant information to the diagnosis or help to differentiate between the two conditions.
