Multifocal electroretinogram P1 implicit times are delayed in type 2 diabetes. The mfERG responses were recorded in dilated right eyes using a Burian–Allen electrode, a 103-hexagon stimulus with a 4-minute m-sequence near 100% contrast on a VERIS System. (A, B) The P1 implicit time (A) and amplitude (B) were averaged and analyzed for all of the ring 2 hexagons. (C) The 103 hexagons with the ring 2 hexagons highlighted in red. Numbers on the plots represent the adjusted P values. Adjusted P < 0.05 was considered statistically significant. Healthy controls: HbA1c ≤ 5.6% (n = 20); PreDM: HbA1c = 5.7%–6.4% (n = 13); T2DM: HbA1c ≥ 6.5% (n = 15).
