Abstract

fetched live from OpenAlex

In Brief Purpose: To report a case of a choroidal macrovessel imaged using enhanced depth imaging spectral domain optical coherence tomography (EDI-OCT) and describe the choroidal features. Methods: Case report: a 42-year-old man presented with metamorphopsia. Multimodal imaging, including color fundus photography, near-infrared reflectance, and EDI-OCT was used to describe a choroidal macrovessel. Results: Initial ophthalmic examination revealed a serpentine-shaped subretinal pattern deep to the retina near the fovea. When the color image was subjected to a red filter, a large diameter vessel could be seen coursing from the fovea to the temporal macula. EDI-OCT of the choroidal macrovessel revealed a thickened choroid and mild deformation of both the ellipsoid zone and the choroidal–scleral junction. En face spectral domain optical coherence tomography at the level of the choroid demonstrated the anomalous vessel. Conclusion: EDI-OCT and en face optical coherence tomography, used in conjunction with other imaging modalities, can be used to demonstrate the presence and pattern of a choroidal macrovessel. A thickened choroid and overlying outer retinal indentation was observed in association of the choroidal macrovessel. These imaging tools can help distinguish this condition from other diagnoses with a similar appearance, such as ophthalmomyiasis. The structure of a choroidal macrovessel is analyzed using enhanced depth imaging spectral domain optical coherence tomography (EDI-OCT). Enlarged vessel caliber, indentation of the choroidal–scleral junction, and increased choroidal thickness are key features reported for the first time. EDI-OCT may allow for a noninvasive assessment and diagnosis of this condition.

Not 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.
