Digital System for ERG and Visual EP Study
 

Main Features:

Electroretinography (ERG):

• registration of rod and maximal ERG in dark-adapted eye

• registration of cone ERG in light-adaptated eye by using white, red, green and blue penlight stimulators

• local ERG registration by using spot LED stimulators (penlights) with concentrators for diagnostics of central disorders

• rhythmical ERG registration with arbitrarily set stimulation frequency

• pattern-ERG registration for the ganglionary cell state assessment

• on/off ERG registration for study of retina structure response on long stimulus

• oscillatory potentials registration in light- and dark-adaptated eye

Visual Evoked Potentials (VEP):

• registration of flash and pattern (checkerboard, vertical/horizontal bars or arbitrarily generated image) visual evoked potentials and “onset”/“offset” stimulation

• registration of rhythmical (steady-state) visual evoked potentials with arbitrary set stimulation frequency

Electro-Oculography:

• registration of pre-adaptation, dark phase and light response
