Abstract
PURPOSE: To evaluate the effectiveness of anterior subtenon triamcinolone (AST) injections in the management of refractory macular edema. METHODS: This is a retrospective case series of consecutive eyes with refractory macular edema treated with AST at a single vitreoretinal surgeon's practice at Toronto Western Hospital, University of Toronto, Canada in 2018 to 2023. Refractory was defined as persistent macular edema with a central subfield thickness of 250 µ m or greater over a 24-week period, receiving at least four intravitreal antivascular endothelial growth factor injections. Vision outcomes and optical coherence tomography features for all eyes were compared for three visits pre-AST treatment and two visits post-AST treatment. RESULTS: Ninety-three patients (119 eyes); diabetic macular edema (26%), and pseudophakic cystoid macular edema (74%), with a mean follow-up duration of 161 days were included. The presence of subretinal fluid ( P = 0.0013), central subfield macular thickness ( P < 0.0001), cube average thickness ( P = 0.0024), and macular cube volume ( P = 0.0017) significantly improved from pre-AST to post-AST treatment. Visual acuity also significantly improved from pre-AST treatment to post-AST treatment ( P < 0.0001). There was no significant change in the intraocular pressures from pre-AST to post-AST ( P = 0.7920), and no complications were noted throughout the follow-up period. CONCLUSION: The findings from this study suggest that AST injections show modest improvement in anatomical and functional outcomes and are safe for the treatment and management of refractory macular edema.

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 it
