Reti Map

Product Detiels

Electrophysiological Test Unit combined with Scanning Laser Ophthalmoscope

Retimap250Simultaneous infrared laser monitoring during electrophysiological function testing with Roland RETImap. New for animal and human topography and function in the same time and area.

An ERG, PERG, PVEP or mfERG stimulus (RETIport-scan) and a new confocal Scanning Laser Ophthalmoscope (920 nm) RC SLO-50 are connected to record ERGs and VEPs projected by a small traditional CRT-stimulus source.

This allows topographic retinal function recordings with the technique of monitor stimulation combined with a laser fundus imaging system. This method is necessary in cases where the retinal position of the stimulus array is not centered onto the fovea, deviates due to fixation problems or for all other cases you want to be sure to stimulate the right area on the retina.


  • integrated in RETIscan (Roland’s multifocal electrophysiology system, mfERG, mfVEP, Perimetry)
  • integrated in RETIport (Roland’s traditional electrophysiology system, ERG, VEP)
  • controlling of stimulus positions and eye movements during examination
  • see an eye-movement-profile during examination
  • repeats sequences with eye-movements automatically
  • for humans and animals Technical Data
