  • Abstract
  • Look Inside

A checkerboard pattern reversal stimulator was built in an infrared fundus camera. Checkerboard sinusoidal pattern reversal stimulus was elicited by a polaroid sheet. The stimulus frequency, size and intensity was alterable. This pattern stimulus was led into the optical pathway of the infrared televi-sion fundus camera and was projected onto the sub-ject's fundus. The state of fixation and the fundus view was observed by infrared illumination without influencing the state of adaptation of the retina. Response from the eye of normal subject by sclero-corneal contact lens electrode showed a sinusoidal waveform.
