Abstract

Objective: this study tended to investigate retina amacrine by flash electroretinogram (FERG) ‎test in patients with color blindness referred to Qods Clinic during 2016-2017.‎ Materials and Methods: In this observational, cross-sectional descriptive study, 25 patients ‎with color blindness referred to Qods Clinic in 2016-2017 were selected by convenient ‎sampling and subjected to FERG. Voltage and latency were determined in the test and were ‎compared with the observed findings in the control group.‎ Results: The voltage recorded in ERG was 73.8±10.03 μV in the case group and 109.2±8.60 μV ‎in the control group, which showed a significant difference between the two groups (P = ‎‎0.0001). The latency of ERG was 56.4±6.05 ms in the case group and 43.9±1.86 ms in the ‎control group, which showed a statistically significant difference between the two groups (P = ‎‎0.0001).‎ Conclusion: Based on the results of this study, it can be concluded that the presence of color ‎blindness causes a significant change in ERG, which is a decrease in voltage and increase in ‎latency‎.
