Abstract

fetched live from OpenAlex

To determine the effect of residual stereopsis on vision-related abilities of low vision (LV) patients with age-related macular degeneration (AMD). Prospective non-randomized observational case series. Inclusion criteria included documented AMD, LV with best corrected visual acuity (BCVA) of 20/50–20/400 in the better eye, and ages between 50 and 90 years. Stereoacuity was measured using the near Frisby Stereotest. Vision related abilities were documented with the VA LV VFQ-48 questionnaire. Twenty-seven subjects with mean age of 84±6 years old were recruited, of which 59.3% (16/27) were female. 59.3% (16/27) of the subjects were not able to see any stereoacuity plate, 25.9% (7/27) had stereoacuity of 340 s of arc (SOA), 11.1% (3/27) had stereoacuity of 170 SOA and 3.7% (1/27) had stereoacuity of 85 SOA. The mean Overall Functional Visual Abilities (OFVA) score was significantly higher in those with stereopsis (2.25±0.99) than those without stereopsis (1.50±0.92) (P=0.028). LV patients with stereopsis have better OFVA than those without. Stereopsis should be considered as a component of LV rehabilitation and considered as an outcome measure in research and clinical practice. Determinar el efecto de la estereopsis residual sobre capacidades relacionadas con la visión de los pacientes con baja visión (BV) y degeneración macular asociada a la edad (DMAE). Estudio observacional de serie de casos prospectivo y no aleatorizado. Los criterios de inclusión incluyeron DMAE documentada, BV con mejor agudeza visual corregida (MAVC) de 20/50 a 20/400 en el mejor ojo, y edades comprendidas entre 50 y 90 años. La estereoagudeza se midió utilizando el Frisby Stereotest de cerca. Las capacidades relacionadas con la visión se documentaron utilizando el cuestionario VA LV VFQ-48. Se reclutó a veintisiete sujetos con edad media de 84±6 años, de los cuales el 59,3% (16/27) eran mujeres. El 59,3% (16/27) de los sujetos no podían ver ninguna placa de estereoagudeza, el 25,9% (7/27) tenía estereoagudeza de 340 arcosegundos (arcseg), el 11,1% (3/27) tenía estereoagudeza de 170 arcseg y el 3,7% (1/27) tenía estereoagudeza de 85 arcseg. El índice de capacidad visual funcional general fue considerablemente superior en aquellos sujetos con estereopsis (2,25±0,99) que aquellos sin estereopsis (1,50±0,92) (p=0,028). Los pacientes con BV y estereopsis tienen mejor índice de capacidad visual funcional general que los que no la tienen. Por tanto, la estereopsis deberá considerarse como un componente de la rehabilitación de la baja visión (RBV), y como una medición de los resultados en la investigación y práctica clínica.

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.
