Keratoconus Management: Navigating Patient Options
Bibliographic record
Abstract
Keratoconus (KC) is a condition which results in progressive corneal thinning. It was first discovered by Dr. John Nottingham in 1854 who described it as “conical cornea” due to the outward bowing appearance caused by the condition. The prevalence of KC is between 0.2 and 4,790 per 100,000 people. KC does not have a gender predilection. It is believed to appear more commonly in South Asian and Middle Eastern populations.
 Keratoconus typically begins in the second and third decades of life although it can develop at any time. The clinical symptoms of the condition include blurred and distorted vision. Patients may present with higher-order aberrations (HOA) ̶ the most characteristic of which is coma ̶ resulting in blurred and double vision. The common signs of KC include corneal protrusion and thinning, prominent corneal nerves, Fleischer ring, Vogt’s striae, and scissors reflex on retinoscopy. The most frequently encountered phenotype is oval cones in the central cornea. The primary diagnostic tool for KC is corneal topography, although pachymetry, including epithelial mapping and corneal tomography, are often performed in conjunction with each other as they aid with early detection and the monitoring of KC progression. 
 Advancements in clinicians’ knowledge of KC and expertise in its treatment, have led to novel therapies. Stopping disease progression is now possible and improving patients’ quality of vision is feasible in many cases.
 Preventive measures halting progression and management of mild and moderate forms of KC are reviewed. Treatment of severe KC will also be briefly reviewed.

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.
