An eye to the future: Acute and long-term neuro-ophthalmological and neurological complications of COVID-19

COVID-19 has had a significant impact on the global population and has produced compelling evidence of non-pulmonary organ dysfunction, including the nervous system. It is vital that specialists in ophthalmology and neurology are informed of the potential complications of COVID-19 and gain a deeper understanding of how COVID-19 can cause diseases of the nervous system. In this review we detail four possible mechanisms by which COVID-19 infection may result in neurological or neuro-ophthalmological complications: (1) Toxic and metabolic effects of severe pulmonary COVID-19 disease on the neural axis including hypoxia and the systemic hyper-inflammatory state, (2) endothelial dysfunction, (3) dysimmune responses directed again the neuroaxis, and (4) direct neuro-invasion and injury by the virus itself. We explore the pathological evidence for each of these and how they may link to neuro-ophthalmological disorders. Finally, we explore the evidence for long-term neurological and neuro-ophthalmological complications of COVID-19, with a focus on neurodegeneration.

Digital Therapeutics in Migraine Management: A Novel Treatment Option in the COVID-19 Era

Migraine is a chronic and often lifelong disease that directly affects over one billion people globally. Because access to migraine medical services is limited, only a minority of migraine patients are treated adequately. This situation worsened during the COVID-19 pandemic. Digital therapeutics (DTx) is an emerging therapeutic approach that opens up many new possibilities for remote migraine management. For instance, migraine management tools, online migraine diagnosis, guideline-based treatment options, digitally networked patients, and collecting anonymized information about migraine attacks and course parameters for scientific evaluation. Various applications of DTx in migraine management have been studied in recent years, such as the usefulness of digital migraine self-management tools in diagnosing and tracking migraine attacks, and the efficacy and safety of digital cognitive behavioural therapy. However, the development of DTx is still in its infancy and still faces many obstacles. The primary goal of this study is to review the latest research on DTx in migraine management, identify challenges, and outline future trends.
