Multi-focal ERG also allows the stimulation of multiple spots simultaneously, producing a changing pattern that is supposed to give more diagnostic information. Studies deemed to provide level III evidence were not included in the assessment. MeSH While the funduscopic changes are subtle, OCT showed alterations of the outer retinal layers in the fovea. Trend analyses provided the clinician with rates of progression, putting the speed of glaucoma progression in the context of patient longevity, whereas event analyses demonstrated a "step" change regardless of the length of time it took for this amount of change to occur. They also stated that it is also worth considering the use of color fundus photographs to assist in documenting changes over time, especially if there is pre-existing retinal pathology. Tsang AC, Ahmadi Pirshahid S, Virgili G, et al. Use of the ERG and EOG in evaluating the effect of sleep OL LI { In glaucoma suspect, HRT parameters such as cup shape measure (CSM) and linear cup-disc ratio (CDR) had significant correlations with PERG amplitudes (p = 0.016 for P50 and 0.049 for N95 in CSM, p = 0.012 for P50 in CDR).

Following pupillary dilatation and immobilization of the dog with a cataleptic drug (l-Polamivet, Hoechst) the electroretinogram (ERG) was performed with the technique of Ganzfeld stimulation. They stated that further studies are needed to determine if this new testing paradigm will be of benefit in monitoring for progression or recovery of ganglion cell function in other non-glaucomatous optic neuropathies including compressive lesions of the optic apparatus, ischemic optic neuropathy, papilledema, and toxic optic neuropathies. Consistent with numerous other reports, accounting for inter-eye differences by normalization to baseline amplitudes and/or by normalization to other features of the same ERG response less sensitive to glaucomatous damage improved both diagnostic performance and correlation to a structural measure of damage severity for the best parameters of all 3 ERG modes.

Ganglion cell loss in early glaucoma, as assessed by photopic negative response, pattern electroretinogram, and spectral-domain optical coherence tomography. The study conclusion was a recommendation to record the PERG under both transient and steady-state conditions to optimize the clinical utility of the procedure. Nesher and Trick (1991) performed a retrospective analysis on the transient and steady-state PERG recorded from 205 subjects. Multi-variate step-wise linear regression analyses showed LogMAR VA was significantly correlated with CMT (p=0.004), and also with the P1 amplitude density in ring 1 (p=0.002); CMT showed significant correlation with P1 implicit time in ring 2 (p=0.013). } Sensitivity was high, but specificity was variable when OCT, FAF, and the positivity of 2 of 3 tests was used as the reference standard.

Schallhorn and colleagues (2018) reported novel ERG findings in a genetically confirmed case of achromatopsia. Multi-focal ERG has been found to be useful in the assessment of localized retinal dysfunction caused by various acquired or hereditary retinal disorders. However, the magnitude of the damage and its likely location in the retina are not clearly known. As there is histopathological evidence showing earlier rod than cone impairment in early ARM, following the rod function with the mfERG might be helpful in diagnosis or for monitoring the progression of early ARM. In addition, this study excluded patients with increased IOP and it could make the results of this study not including all type of glaucoma. Toxic retinopathies, including those caused by intraocular metallic foreign bodies, Vigabatrin and Chlorpromazine, Retinal vascular disease [e.g. Applications are available at the American Dental Association web site. they stated that further studies with long-term results will be useful in clarifying the value of mfERG in evaluating early retinal toxicity due to HCQ.
