title: The correlation of visual evoked potentials (VEP) and visual field indices (Octopus G1) in glaucoma and ocular hypertension.
abstract: Flash evoked responses and the visual field indices (VFI) of the Octopus G1 program were recorded from 42 eyes of 21 patients, aged 23-76 years (mean 51 years); 29 eyes had open-angle glaucoma (OAG) and 10 ocular hypertension (OH). Three eyes were normal. The early component of the VEP called P 120 had lower amplitude in glaucomatous eyes compared with normal or hypertensive eyes. Mean sensitivity (MS), mean defect (MD), and short time fluctuation (SF), indicative of diffuse non-specific nerve fiber los, correlated significantly (P less than 0.05). Reliability factor (RF), which is indicative of psychodynamic factors, also correlated significantly (P less than 0.05) in eyes with OAG.
