Résumé
The visual function of diabetic eyes was assessed to evaluate spatial-sweep steady-state pattern electroretinography (swpPERG) as a potential high-sensitivity analysis method. Data from 24 control eyes, 28 diabetic eyes without diabetic retinopathy (DR), and 30 diabetic eyes with DR (all with best-corrected visual acuity [BCVA] better than logMAR 0.05; median age, 51) in response to spatial-patterned and contrast-reversed stimuli of sizes 1 (thickest) to 6 were converted into the frequency domain using a Fourier transform and expressed as signal-to-noise ratios (SNRs). SNRs of diabetic eyes, both with and without DR, were lower than those of controls (P < 0.05), and those of DR eyes were lower than those of diabetic eyes without DR (P < 0.05). The SNRs were correlated with ganglion cell layer volume measured using optical coherence tomography (OCT) and foveal vascular length density at the superficial retinal layer measured using OCT angiography (P < 0.05 or < 0.01, according to stimulus size). Therefore, swpPERG SNRs could detect fine reductions in visual function in diabetic eyes and were particularly low in DR eyes. Moreover, SNRs were correlated with inner retinal morphological changes in diabetic eyes, both with and without DR. swpPERG may therefore be useful for detecting fine fluctuations in visual function in diabetic eyes.
