“…CVD was also revealed to be affected due to family history, where students who had family members with this deficiency were more susceptible to CVD. While the current study did not consider the factor of family history, gender was a considered factor, which, however, as opposed to the study by Khairoalsindi et al, 13 had no significant association with total CVD. Our results were similar to that of a study by Khalid et al, 1 who found no significant association between gender and CVD.…”

“…Gender was found to have a statistically significant relation with red-green color vision deficiency; however, it was nonsignificantly related to the total CVD. As compared with the literature review, Khairoalsindi et al 13 studied the extent and factors affecting CVD among health science students wherein the researchers used survey method and deployed 24-plate Ishihara’s test of color vision chart among 1,126 students. It was observed that males experience a higher prevalence of CVD as compared with females.…”

Objective The current research was conducted to evaluate the frequency of color-vision deficiency among dental students of King Khalid University College of Dentistry, Saudi Arabia. Materials and Methods A cross-sectional study was performed among 203 dental students working as interns at male and female dental clinics of King Khalid University College of Dentistry (KKUCOD), Saudi Arabia. The Ishihara color-vision deficiency (CVD) test with 24 plates was used for diagnosis of the problem. Analysis of the data was done by performing Chi-square tests using SPSS software version 20. Results The frequency of total CVD was found to be 3.9%. While the association of gender with total CVD was observed to be statistically nonsignificant, a statistically significant relation was drawn with red-green color deficiency. Out of the total of 203 patients, 44 males were identified with red-green color deficiency, whereas only three females were found to have this condition, therefore revealing that CVD is more prevalent in males. Age was found to have a significant association with red-green color vision deficiency, protanopia, and total CVD. Conclusion A total of 20.19% male dental students had red-green color vision deficiency compared to 1.4% in female students. The dental students must be aware of their congenital color vision deficiency and its impact on their professional life. Screening of such dental students and professionals is quite important so that they can tackle the color vision problems well without having detrimental effect on their future dental practice.

“…A published study with findings that are consistent with our own suggests that color blindness and family history are strongly correlated. 15 One of the clinical research studies that has been published indicates a positive association between family history and color blindness, which is coherent with the findings of our current study. 15 In our study we found out that there was an association of color blindness with night blindness.…”
