Abstract

fetched live from OpenAlex

PURPOSE: To determine the outcomes of patients with sickle cell retinopathy who experienced at least one episode of being lost to follow-up (LTFU) compared with those who attended all appointments. METHODS: Adult patients with sickle cell retinopathy who visited Wills Eye Hospital Retina service (January 2012-December 2021) with >2 visits were reviewed for LTFU events, defined as failure to return for a follow-up appointment within 6 months of the scheduled date. RESULTS: One hundred and eighty-one eyes of 94 patients were included. Fifty-one patients (99 eyes) attended all appointments ("attended group"), whereas 43 patients (82 eyes), or 46%, had at least one LTFU event ("LTFU group"). The mean (SD) LTFU duration was 470 (329) days. In the LTFU group, mean (SD) VA was significantly worse at the final visit (logMAR 0.45 (0.63), Snellen 20/56) and at the post-LTFU visit (0.36 (0.59), 20/46) compared with the pre-LTFU visit (0.3 (0.47), 20/40, P = 0.001). In the attended group, mean (SD) VA was significantly better at the final visit (0.41 (0.63), 20/51) compared with the initial visit (0.52 (0.78), 20/66, P = 0.038). CONCLUSION: Patients with sickle cell retinopathy with an LTFU event have worse visual outcomes compared with patients who attend all appointments.

Full frame distilled prediction

Teacher imitation

Not 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.
