Introduction: Color blindness is X-linked recessive inherited disorder that occurs mostly in males and is transmitted through females. Many people with color blindness may remain undetected. Thus the present study aims to evaluate the incidence of color blindness among undergraduates of Kathmandu University. Methods: A cross-sectional study was conducted among 825 undergraduates, aged 17-25 years, from June to August 2018, in Kathmandu University, Kavre, Nepal. The Ishihara plates were used to evaluate the color vision of students under natural day light condition.Results: Study revealed that 24 (2.9%) undergraduates were color blind which include 24 male (5%) and no female. Among the color blind, five (20.3%), three (12.5%), two (8.33%) and 14 (58.33%) males were the victims of deuteranomaly, deuteranopia, protanomalia and total color blindness respectively. Color blindness is prevalent among the Brahmin 10 (3.9%), followed by Chettri 10 (2.72%) and Newar 4 (2.24%). Conclusions: Prevalence of color blindness is found to be higher in males 24 (5%) than females 0 (0%). Total color blindness is the most prevalent in our study. Screening enables the students to become aware of limitations and devise ways of overcoming them.

Institutional Review

The synergistic and harmonic functions of retina, optic nerve, part of thalamus and visual cortex are essential for the perception of color: human color vision is trichromatic i.e. the mixture of red, green and blue lights. The present cross-sectional study was conducted in August to October 2018. The ethical approval was obtained from Institutional Review Committee (IRC) of Nepal Medical College. After obtaining consent from the participants, the study was carried out among health science students of age group 18-25 years at Jorpati, Kathmandu, Nepal. The number (n) of sample size was 300; (male, n=150, female, n=150). The assessment of color blindness was done with the help of Ishihara Chart (“Ishihara Type Tests for Color Blindness”-38 plates (2002) Eye Care- Ludhiana, India). Among the study group (male, n=150, female, n=150), the color deficiency were found in male participants only; n=7, which is 2.33% of total participants (n=300). None of the female participants were found to be color blind/weak. Among the color deficient (n=7), protanomaly detected in 1, deuteranomaly in 2 and deuteranopia in 4. Hence, the present students of health stream are future health workers, whose observation apt to clinical examination is instrumental to treat patients; therefore, they must be aware and circumspect of their color vision to discharge their duties to the patients in a better way.

Aim: To find out the prevalence of color blindness among medical students. Study Design: Descriptive cross-sectional. Place and Duration of Study: Study was conducted at Chaudry Mohammad Akram teaching and research hospital, Superior university during December 2020 to May 2021. Methodology: All the medical students having age range between 21-25 years were included in the study. An ophthalmologist did ocular examination, after that color vision was checked by putting Ishihara plates. The score less than 12 out of 14 red-green test plates were labelled as color blind. Data was analyzed by using the SPSS version 20. Chi-square was used to find out the association of color blindness with age groups and gender. p-value less than 0.05 was considered as significant. Results: The mean age with standard deviation of study participants was 23.27 ± 0.87 years. The prevalence of color blindness among medical students was 2% out of which 1.7% were having strong red-green deficiency while only 0.3% were with mild red-green deficiency. Majority of participants with color blindness were noted in the age group of 22 years while very few were in the other age groups of medical students but these results were non-significant. On the other hand, all the color blind was male but no association was found as the p-value was more than 0.05. Conclusion: Current study reported that about 2% of medical students are affected by color vision deficiency. So there is a need of proper visual screening program among medical undergraduates for early detection of color blindness and counselling session for them.

Objective: To determine the frequency of color blindness among male professional drivers of Karachi- Pakistan and the difficulties they experience while driving. Study Design and Setting: A cross-sectional study was conducted aomng 300 male drivers with valid driving licenses operating on local and long routes in Karachi. Methodology: The study was done at various locations in the city of Karachi from September to November 2017. The subjects were tested for vision and color blindness with the help of Snellen’s chart and Ishihara chart respectively. A précised questionnaire was developed keeping in view the study objectives. SPSS version 21.0 was used for data entry and its analysis. Each questionnaire was thoroughly studied and seen for missing data or information before entry. A written informed consent about the study was provided to the subjects in the form of a plain language statement attached to the questionnaire. This study was approved by the ethical review board of Karachi Institute of Medical Sciences (KIMS). Results: Amongst the 300 participants 7 (2.33 %) of the drivers were found to have complete color blindness while 2 (0.66%) were partially colour blind. They preferred day time driving and experience difficulties in recognizing traffic signals and vehicle lights. Conclusion: The frequency of colour blindness was found to be low but it was observed that colour blind drivers face a lot of difficulties while driving. Therefore, easy and practical changes should be made, like shape-coding of signals, and continuous research-based modifications are required to aid these drivers.

Color Deficiency

Abstract 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.

Abstract A study by Yaruss and Quesal (2002), based on responses from 134 of 239 ASHA accredited graduate programs, indicated that approximately 25% of graduate programs in the United States allow students to earn their degree without having coursework in fluency disorders and 66% of programs allow students to graduate without clinical experience treating people who stutter (PWS). It is not surprising that many clinicians report discomfort in treating PWS. This cross-sectional study compares differences in beliefs about the cause of stuttering between freshman undergraduate students enrolled in an introductory course in communicative disorders and graduate students enrolled and in the final weeks of a graduate course in fluency disorders.
