“…The Fourier transform has been used by several authors for measuring the OPs [9,[14][15][16]. The power measurement was regarded as a reliable quantitative method for detecting diabetic retinopathy at an early stage [9].…”

“…The power measurement was regarded as a reliable quantitative method for detecting diabetic retinopathy at an early stage [9]. Van der Torren [9] observed a reduced OP power in the patients with early diabetic retinopathy, but did not show a definite statistical analysis in their findings. A significant reduction of the total power of the OPs was found in the BDR group in dark and light adaptation in our study.…”

“…However, several authors reported that no changes in the OPs were observed in patients with microaneurysms and hemorrhages [8]. Recently, the power measurement was used in a clinical study to analyze the OPs and appeared to be a reliable method of detecting diabetic retinopathy at an early stage [9].…”

The oscillatory potentials of the electroretinogram in dark and light adaptation were evaluated by Fourier transform in 87 diabetics and 74 age-matched controls. The study consisted of four groups: normal control, no observable diabetic retinopathy, background diabetic retinopathy and proliferative diabetic retinopathy. A reduction in the amplitude of each oscillatory potential, the summed amplitudes, the area and the total power of the oscillatory potentials as well as delayed implicit time of each oscillatory potential peak in dark and light adaptation could be found in patients with background diabetic retinopathy and proliferative diabetic retinopathy. The amplitude of oscillatory potential 4 in dark adaptation and the total power of the oscillatory potentials in light adaptation seemed to be affected in patients with no observable diabetic retinopathy. The implicit time of oscillatory potential 2 in dark adaptation was valuable to distinguish between patients with no observable diabetic retinopathy and background diabetic retinopathy.

“…For example, the high-frequency wavelets recorded on the ascending limb of the electroretinogram (ERG) b-wave (oscillatory potentials), thought to reflect inner retinal inhibitory circuits, are smaller in those with diabetes with no evidence of background diabetic retinopathy as defined using photography [4] or fluorescein angiography [5]. A reduction in amplitude of the response to a contrast reversing pattern checkerboard (pattern ERG) has also been observed in eyes that do not have overt clinical signs of retinopathy [6].…”

Neuronal dysfunction has been noted very soon after the induction of diabetes by streptozotocin injection in rats. It is not clear from anatomical evidence whether glial cell dysfunction accompanies the well-documented neuronal deficit. Here, we isolate the Müller cell driven slow-P3 component of the full-field electroretinogram and show that it is attenuated at 4 weeks following the onset of streptozotocin-hyperglycaemia. We also found a concurrent reduction in the sensitivity of the phototransduction cascade, as well as in the components of the electroretinogram known to indicate retinal ganglion cell and amacrine cell integrity. Our data support the idea that neuronal and Müller cell dysfunction occurs at the same time in streptozotocin-induced hyperglycaemia.

The postural variations in the retinal microcirculation in glaucomatous patients were studied by evaluation of the oscillatory potentials (OPs) of the ERG. The OPs in scotopic adaptation were examined in subjects with primary open-angle glaucoma and in an age- and sex-matched normal control group in different body positions (seated, supine, anti-Trendelenburg, Trendelenburg). In the seated position, the difference of mean OP amplitude between the control group and the glaucomatous patients was highly significant (p < 0.001). In the normal subjects the OP amplitude in the Trendelenburg position was statistically lower with respect to the values obtained in all other positions (p < 0.05). In the glaucomatous patient group, the OP amplitude in the anti-Trendelenburg position was increased as compared to the other positions (p < 0.05). The study showed a reduction in amplitude of OPs in glaucomatous patients and their different behaviour in both groups with changes in body position.
