Advances in Understanding Visual Disorders Linked to Cortical Dysfunction – Volume II

Building on the success of the Research Topic Advances in Understanding Visual Disorders Linked to Cortical Dysfunction, this second volume aims to capture the next wave of actionable advances and recent progress in the field of neuro-ophthalmology and cortical visual dysfunction.The cerebral cortex plays a central role in vision, one of the most intricate sensory functions of the human brain. Because of this dependence, cortical dysfunction can disturb sight through a wide range of mechanisms. Affected individuals may experience anything from outright vision loss, as seen in hemianopia and cortical blindness, to intricate perceptual distortions such as hallucinations, metamorphopsia, and simultanagnosia. These conditions can arise from disruption in the primary visual cortex, the numerous extra-striate areas responsible for processing distinct visual submodalities, or both. Consequently, the resulting clinical picture is broad, spanning deficits in eye movement control alongside disturbances in visual perception itself. A current interest is the association of visual cortical dysfunction with what are considered primarily eye disorders, such as glaucoma. Whether these changes are remote effects of the eye disease or represent independent, parallel pathology is an issue of active current research. The glymphatic system is now identified in both eye and brain, but are there glymphatic disorders that affect both? Grasping both the anatomical substrates and pathological mechanisms behind visual cortical dysfunctions matters greatly to neuro-ophthalmologists, emergency neurologists, and clinicians across related fields, including those working in neurodegeneration, epilepsy, stroke, and neuropsychiatry.As a continuation of the first volume, this second Research Topic aims to extend that perspective by gathering further contributions across the wide range of visual disturbances rooted in cortical dysfunction. The intent is to shed light on underlying disease mechanisms, identify viable therapeutic targets, and strengthen approaches to diagnosis and clinical management. Submissions that advance knowledge and drive the field of neuro-ophthalmology forward are especially encouraged.To gather further insights into the neurological complexity of cortically-driven visual disorders, this Research Topic welcomes a range of manuscript types supported by the journal (Original Research, Reviews, Brief Research Reports, Perspectives, Mini-Reviews, and more), addressing, but not limited to, the following themes:- Uncovering the range of causes and mechanisms underlying cortically-driven visual impairment. - Characterizing specific visual disorders arising from cortical abnormalities.- Exploring the association of visual cortical dysfunction with primarily eye disorders, such as glaucoma.- Discovering biomarkers that enable earlier diagnosis and more personalized treatment.- Refining diagnostic techniques for more precise clinical assessment.- Investigating emerging approaches to visual restoration.- Applying neuroimaging methods to better understand visual disorders from a cortical standpoint.Together, these themes aim to deepen understanding of how cortical dysfunction and visual impairment intersect, with the ultimate goal of advancing clinical practice and research across neuro-ophthalmology and cognitive neurology.Articles will be published online as soon as they are accepted after peer review and approved for publication.Sign up now to participate in this exciting Research Topic.
