Background

Recent studies highlight the importance of the temporal domain in visual processing.

Purpose

This paper presents a robust and reliable dichoptic tool for evaluating the Critical Flicker Frequency threshold in both eyes.

Results

3.9

amblyopic eyes show poorer visual temporal processing than fellow eyes

More results

Another important issue to investigate is the cortical interactions arising between the flicker stimuli of both eyes.

More results

Experiments were designed to evaluate the Critical Flicker Frequency threshold through a psychophysical test, based on a discrimination task with a stimulus duration of 1 s, based on a temporal alternative forced-choice paradigm.

“

Conclusion

In this paper we describe the system and methods in detail and provide all necessary computer code and other details that will enable an easy and quick adaptation of the method by scientists interested in studying the temporal resolution of the visual system in general, and in studying inter-ocular differences or interactions in particular.
