Electroretinography can provide objective assessment of inner retinal function prior to atrophic change on OCT

Frequency Doubling Technology Visual Field Loss in Fabry Subjects Related to Retinal Ganglion Cell Function as Explored by ERG and OSOME

“…This longer latency may be related to retinal ganglion cells malfunction; at least, it may be considered an early dysfunction of the inner retinal layer. 34 Again here we can identify very large effect size (>1.2) for most of the peak time recorded (1.213 for PhNR-PT-4, 1.164 for PhNR-BT-4, 1.226 for PhNR-PT-0, 1.152 for PhNR-BT0 and 1.331 for PhNR-BT2). Expressed in terms of area under receiver operator characteristic plots (AUC) they range from 0.85 to 0.94.…”

Day one ‘patch‐off’ visual loss due to retinal ischaemic injury: can we blame sub‐Tenon's or peribulbar anaesthesia?

“…However, these variants of CRAO have residual RAPD and reduced b‐wave on electroretinography (ERG) resulting from diffuse and permanent inner retinal damage. Further studies using OCT angiography and electro‐diagnostics are needed to determine whether PAMM in the setting of cataract surgery represents an even milder form of ‘transient’ or ‘partial’ CRAO or a different type of ischaemic retinopathy altogether. Finally, the authors considered the possibility of drug toxicity or reaction rather than retinal ischaemia, but this is unlikely given the atypical OCT features.…”
