{"title":"Prevalence of color vision deficiency in medical students at a Saudi University.","authors":"Naela B Alamoudi, Razan Z AlShammari, Reem S AlOmar, Nouf A AlShamlan, Abdullah A Alqahtani, Naheel A AlAmer","doi":"10.4103/jfcm.jfcm_235_21","DOIUrl":"10.4103/jfcm.jfcm_235_21","url":null,"abstract":"<p><strong>Background: </strong>Color vision deficiency (CVD) affects approximately one in 12 men and one in 200 women in the world. It is considered a problem in the medical field since the color is often used as a sign in the practice of medicine, in observational assessment, diagnosis, and follow-up. These conditions make the appreciation of color essential in doctors' lives, thus we aimed at finding the prevalence and predictors of CVD in medical students.</p><p><strong>Materials and methods: </strong>This cross-sectional study included 1115 medical students. A pretested questionnaire consisting of personal data, history of vision problems, familial color vision defect, eye surgery, bad trauma on the head or eyes, drugs taken or chemicals exposed to, other health problems, and whether sufficient amount of Vitamin A is taken was used. This was followed by the screening of the participants for CVD using the Ishihara 15-plates test.</p><p><strong>Results: </strong>A total of 1115 students participated in the study; 52.2% were females and the mean age of the participants was 21.7 years (±1.4).
