Abstract:
Background: Color vision deficiency CVD is the absence of the competency to discriminate between certain colors. However, congenital red-green CCVD is an X-linked recessive disease; occurs almost exclusively in males, while the blue type is acquired. The progression of CVD is known to differ from euthenics groups and geographical regions of the world. The objective of the study: The existing study aimed to screen and ascertain CVD among laboratory students at the University of Khartoum (U of K), Sudan. Subjects and Methods: by using questionnaires statistical techniques and Ishihara charts. A group of 264 medical laboratory students with a mean age of (21 years ±2.4 standard deviation) was invited to the cross-sectional study. Results: The study revealed no significant association was found between age (P <0.685), gender (P <0.464), and CVD as well as between year of education (P < 0.405), region of birth (P <0.92), and CVD (P <0.05), respectively. The prevalence of definitive CVD was 1.5%. A Hundred percent (100) % of CVD victims are unaware of their condition. Females accounted for (73.1%). Three-quarters of the students with CVD were in the first year, whereas one-quarter is in the final year. No significant associations were enumerated between CVD status and region of birth. Conclusions and Recommendations: The study concluded that several medical students with CVD remain ignorant of their circumstances and subsequently may have numerous issues in their medical education, particularly in ascertaining color slides, and specimens, and examining certain physical signs. We recommend early screening of all school-age children, proper handling for medical students with definitive CVD to take care of their health, and being alert to their condition when choosing their specialties for the future. This will ensure avoidance of mistakes and any consequent medico-legal litigations in their professional lives.
