Abstract
PURPOSE: Endophthalmitis following intravitreal anti-vascular endothelial growth factor injections is frequently caused by Streptococcus viridans organisms and tends to be aggressive. Herein, we present a case of postinjection Streptococcus viridans endophthalmitis presenting in an atypically delayed fashion with good visual outcome. METHODS: Single clinical case report. RESULTS: A 91-year-old woman treated with aflibercept for exudative age-related macular degeneration of the left eye presented to the emergency department with mild pain and visual acuity decline to counting fingers, pigmented anterior chamber cells and vitreous haze 7 weeks after her most recent intravitreal injection. She had no symptoms of systemic infection. The presumptive diagnosis initially was vitreous hemorrhage. Over 10 days of observation, she developed worsening pain and vitritis suggestive of endophthalmitis, leading us to perform vitrectomy with intravitreal vancomycin and ceftazidime. Vitreous biopsy was culture positive for Streptococcus intermedius , a type of viridans streptococcus typically associated with head and neck abscesses. The infection resolved and the patient's visual acuity returned to her baseline of 20/100, with no recurrence of infection after 4 months of follow-up. CONCLUSSION: The virulence of viridans streptococci capable of producing postinjection endophthalmitis may vary widely. Infection ought to be suspected even in cases of delayed-onset intraocular inflammation.

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
