Near-Infrared Autofluorescence in Non-Infectious Uveitis: A Review
Bibliographic record
Abstract
This review offers a comprehensive synthesis of current evidence on near-infrared autofluorescence (NIR-AF) in non-infectious uveitis, highlighting its strengths, limitations, and role in diagnosis, monitoring, and understanding disease mechanisms. Unlike blue-light autofluorescence, which mainly detects lipofuscin, NIR-AF visualizes melanin and related compounds in the retinal pigment epithelium (RPE) and choroid, providing deeper penetration, reduced phototoxicity, and greater comfort. Across entities like Vogt-Koyanagi-Harada disease, MEWDS, punctate inner choroidopathy, APMPPE, and Fuchs' heterochromic iridocyclitis, NIR-AF reveals patterns often invisible on conventional imaging-detecting subclinical lesions, differentiating active from inactive disease, and tracking RPE changes over time. Its persistence in showing hypoautofluorescent or hyperautofluorescent lesions after clinical resolution offers unique insight into residual or subclinical inflammation. The technique complements OCT, fluorescein, and indocyanine green angiography, adding a melanin-specific layer to multimodal imaging. Limitations include a weaker signal compared to BL-AF, susceptibility to media opacities, equipment-dependent variability, and lack of standardized interpretation criteria. While it cannot quantify choroidal melanin loss directly and image acquisition can be challenging, its non-invasive, repeatable nature and diagnostic yield make it a promising tool for longitudinal uveitis care. Further prospective studies, standardization, and AI-driven analysis could expand its clinical impact, potentially cementing NIR-AF as an essential component in uveitis imaging strategies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
