Juxtafoveal Retinal Arterial Macroaneurysm Diagnosed on Ancillary Imaging
Bibliographic record
Abstract
Purpose: To describe a case of retinal arterial macroaneurysm, a rare, focal arterial dilatation that is commonly found temporally within the first 3 orders of retinal arterial bifurcations. Methods: An observational case report was evaluated. Results: A 49-year-old man with prediabetes and hypercholesteremia presented with decreasing vision and a paracentral scotoma in the right eye. His ocular history was insignificant. There was significant intraretinal and subretinal fluid with perifoveal exudates. After 2 intravitreal injections of aflibercept for a tentative diagnosis of branch retinal vein occlusion, there was no improvement. Intravenous fluorescein angiography showed a small retinal arterial macroaneurysm less than 60 µm from the foveal avascular zone that was treated with low-power focal laser photocoagulation. This resulted in complete resolution of the macular edema with significant improvement in visual acuity. Conclusions: This rare and successfully treated case of an exudative juxtafoveal retinal arterial macroaneurysm highlights the importance of multimodal imaging in establishing an accurate diagnosis.

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.
