“…5–8 We have refined the methods previously reported in the 1993 baseline 5 and 1994 1-year follow-up 6 articles. For the purpose of identifying visual field abnormalities in patients with optic neuritis, we developed the current methods based on a visual field classification system developed in 1999 for the Ocular Hypertension Treatment Study (OHTS).…”

“…The classification system has evolved during the past 15 years based on the UCDVFRC’s previous experience with the OHTS. 9–14 We have refined the methods previously reported in our ONTT 1993 baseline 5 and 1994 one-year follow-up 6 studies. The evolution of our Visual Field Classification System involved developing specific parameters and definitions of the OHTS visual field patterns of loss.…”

Purpose: To evaluate the ability of GDx with variable corneal compensator (VCC) compared to visual-evoked potentials (VEPs) and standard automated perimetry (SAP) in the detection of early optic nerve damage in patients with multiple sclerosis (MS). Methods: 46 eyes of 23 MS patients were included. Ten of them had a history of acute retrobulbar optic neuritis. A control group of 20 normal subjects was also included. All subjects underwent a complete ophthalmological examination and testing with SAP, GDx VCC and VEPs. Results: 19 eyes (41.3%) were abnormal with GDx VCC compared to 38 eyes (82.6%) with SAP and 31 (64.4%) with VEPs. In the optic neuritis group, 9 eyes (69.2%) had optic nerve pallor; SAP was abnormal in 8 of these eyes (61.5%) while VEPs and GDx VCC were abnormal in 6 eyes (46.1%). 2/20 eyes (10.0%) in the control group gave a false-positive abnormal result with SAP. GDx VCC and VEP were normal for all the eyes in the control group. Conclusions: GDx VCC is less able to detect early defects in MS patients compared to the currently used standard techniques of SAP and VEPs.

“…[2526] The significant defects involving central 2 mfVEP rings have been classified as central scotoma, defect involving central four rings as cecocentral scotoma, defect in upper or lower field of 6 mfVEP rings as altitudinal defect, temporal or nasal field defect of 6 mfVEP rings as hemianopia defect and defect involving all the quadrants in mfVEP six rings as diffuse or generalized defect.…”

Purpose:To investigate the effect of optic neuritis (ON), ischemic optic neuropathy (ION) and compressive optic neuropathy (CON) on multifocal visual evoked potential (mfVEP) amplitudes and latencies, and to compare the parameters among three optic nerve disorders.Materials and Methods:mfVEP was recorded for 71 eyes of controls and 48 eyes of optic nerve disorders with subgroups of optic neuritis (ON, n = 21 eyes), ischemic optic neuropathy (ION, n = 14 eyes), and compressive optic neuropathy (CON, n = 13 eyes). The size of defect in mfVEP amplitude probability plots and relative latency plots were analyzed. The pattern of the defect in amplitude probability plot was classified according to the visual field profile of optic neuritis treatment trail (ONTT).Results:Median of mfVEP amplitude (log SNR) averaged across 60 sectors were reduced in ON (0.17 (0.13-0.33)), ION (0.14 (0.12-0.21)) and CON (0.21 (0.14-0.30)) when compared to controls. The median mfVEP relative latencies compared to controls were significantly prolonged in ON and CON group of 10.53 (2.62-15.50) ms and 5.73 (2.67-14.14) ms respectively compared to ION group (2.06 (-4.09-13.02)). The common mfVEP amplitude defects observed in probability plots were diffuse pattern in ON, inferior altitudinal defect in ION and temporal hemianopia in CON eyes.Conclusions:Optic nerve disorders cause reduction in mfVEP amplitudes. The extent of delayed latency noted in ischemic optic neuropathy was significantly lesser compared to subjects with optic neuritis and compressive optic neuropathy. mfVEP amplitudes can be used to objectively assess the topography of the visual field defect.
