The use of optical coherence tomography in neurology: a review
Bibliographic record
Abstract
Optical coherence tomography is a non-invasive, cost-efficient technique that provides high-resolution in vivo imaging of retinal tissue. The peripapillary retinal nerve fibre layer and macular ganglion cell complex are surrogate markers of neuroaxonal integrity in not only the eye, but also the CNS. Retinal atrophy may occur in tandem with CNS pathologies as a result of injury to ganglion cells, direct degeneration of the pregeniculate pathway, or retrograde trans-synaptic degeneration secondary to postgeniculate lesions. In this review, we outline the basic principles of optical coherence tomography and discuss its application to managing patients with demyelinating disorders, idiopathic intracranial hypertension, stroke, neurodegenerative conditions, and mitochondrial disorders. We demonstrate that measurements of peripapillary retinal nerve fibre layer and macular ganglion cell complex thickness are paramount in diagnosing and monitoring neurological disorders, including those with subclinical disease progression.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
