GDx-VCC performance in discriminating normal from glaucomatous eyes with early visual field loss

Abstract: In our sample of eyes with early VF loss, GDx-VCC showed moderate-to-good discriminating ability. Among the best performing parameters, NFI had the largest AUROC, but several glaucomatous eyes (21, 43.8%) had NFI <30. This suggests that algorithm for NFI calculation requires some refinement when eyes with early VF loss are evaluated.

“…Medeiros et al 6 reported that the GDx VCC-related index showing the highest AROC for glaucoma detection (average MD: -4.87 dB) was NFI (AROC, 0.91). Da Pozzo et al 7 reported that GDx VCC showed a moderate-to-good discriminating ability. Our previous report also showed that GDx VCC shows only a moderate ability to distinguish normal eyes from eyes with early glaucoma (mean MD: -3.32±2.20 dB).…”

“…20 Several studies have evaluated the diagnostic capability of GDx VCC in glaucoma detection, especially at its early stages. [4][5][6][7] Weinreb et al 4 showed that the parameter with the largest AROC (0.83) for discriminating 54 glaucomatous eyes (average MD: 6.49 dB) from 40 healthy eyes was the average RNFL thickness within the superior quadrant. In the study conducted by Resu and Lemij, 5 they reported that the sensitivity of the NFI to identify glaucoma patients with mild, moderate, and severe damage was equal to 83.8%, 92.9%, and 90.1%, respectively, at the cutoff level of ≥40.…”

“…En el presente estudio hemos demostrado, al igual que diversos estudios anteriores, que los pará-metros analizados por el GDx-VCC son útiles para discriminar entre sujetos normales y glaucomatosos con defectos leves o moderados en la PA (6,7,(17)(18)(19)(20)(21). La mayoría de los parámetros presentaron diferencias significativas entre sujetos normales o hipertensos y glaucomatosos, no encontrándose para ningún parámetro diferencias entre controles e hipertensos oculares.…”
