Cone electroretinograms (ERGs) in response to different color flashes were examined using a Ganzfeld stimulus in 19 eyes after successful retinal detachment surgery. In the operated eyes, the short wavelength sensitive (S-) cone b-wave was reduced more than the mixed long (L-) and middle (M-) wavelength sensitive cone b-waves. The ratio of the S-cone ERG b-wave amplitude between operated eyes a...

Qualitative defects and resistances in 94 used gold foil electrodes were examined. The electrodes were divided into four groups of varying resistances and gold coating defects. Ten were randomly selected from each group to measure standard photopic electroretinograms (ERGs) in a normal subject. Ten new electrodes were used as controls. There was no significant difference among the electrode gro...

Using prolonged dark adaptometry, standard dark adaptation (DA) and prolonged DA full-field electroretinograms (ERGs), we analysed the retinal function in patients with Bothnia dystrophy (BD), a variant of recessive retinitis punctata albescens (RPA). A compromised rod and cone function, a likely dysfunction of the Müller cells, and indications of disturbed neuronal function of the inner retina...

There are presented the computational simulations of the optoelectronic effects in the biophysical processes involved by light absorption and the transmission of the membrane generated potential from the receptor cells to the neurons. The physical system is the compound eye of Drosophila Melanogaster flies. The experimental electroretinograms recorded at various frequencies between 8 and 60 Hz ...

PURPOSE/METHOD To present a 72-year-old woman affected by non-arteritic anterior ischemic optic neuropathy (NA-AION). To our knowledge, this clinical case, showing a bilateral form of NA-AION, is uncommon as only very few similar reports have been published in the scientific literature at this time. RESULTS/CONCLUSIONS Visual acuity was reduced to 6/20 in both eyes, color vision was absent an...

Twenty hatchling chickens were injected intravitreally every 4 days from day 2 to day 16 with dimethyl sulphoxide (DS) in one eye and DS or formoguanamine dissolved in DS (FG.DS) with or without occlusion in the other (FG.DS.MD, DS.MD, FG.DS). At day 16, the FG.DS.MD eyes failed to show the high refractive myopia and showed less axial elongation than that developed by the DS.MD eyes. Electroret...
