It has been reported that refractive errors (RE) and binocular vision (BV) anomalies are common among university students. In this study we aimed to assess RE and BV status among university students in Saudi Arabia, and its relation to the academic performance. We recruited 109 participants (aged from 18 to 21 years). Visual acuity (VA) and objective refraction were used to assess the refractive status. Cover test, near-point convergence (NPC) and stereopsis tests were used to assess the BV status. Convergence insufficiency symptom survey (CISS) was applied to quantify near-work related symptoms. Mann-Whitney U test (p value was set as p < 0.05) was used to compare VA, CISS, NPC and the academic performance between the groups who had heterophoria versus orthophoria. We found that there was only 38% emmetrope, while the percentage of heterophoria was 45.8%. The academic performance was not statistically different among the two groups, but CISS and stereopsis scores were significantly different (p < 0.03). We concluded that RE and BV anomalies were common among university students in Saudi Arabia, but did not affect the academic performance. More studies are warranted to understand the low scores of CISS and stereoacuity, and their association with RE and BV anomalies.

Purpose:  To see the effect of binocular vision problems on childhood academic performance and to record the teacher's perspectives about childhood eye care in Khartoum State of Sudan. Place and Duration of Study:  A descriptive cross-sectional study done among the school going children in the Khartoum State of Sudan during the year 2018. Study Design:  Descriptive cross sectional study. Material and Methods:  Three hundred and forty (340) primary school children’s were recruited for study by convenient sampling technique during the academic year 2018. After relevant history, ocular examination was performed. It included visual acuity measurement, assessment of refractive errors and binocular function tests. Academic performance of the children was recorded from academic records of the children. Finally, the qualitative data was derived from teachers’ perspectives about childhood eye care. Results:  Mean age of the participants was 11.96 ± 1.63 years. The findings revealed that (78.6%) of children achieved poor academic performances with decompensated exophoria at near. 52.7% children with poor academic performances had weak positive fusion reserve at near P = 0.04. 37.2% of the poor performers had convergence insufficiency. Fort eight percent of females with ocular complaints achieved poor academic performances P = 0.034. With regard to teacher's perspectives about childhood eye care, 98.8%believed that the vision problems had effect on the academic record of the children. Seventy percent of the teachers reported that the students did not undergo eye examinations before joining school. Conclusion:  Convergence Insufficiency and weak positive fusional reserve at near has a significant effect on academic performances.

Educational institutions in Saudi Arabia extended e-learning until the third semester of the academic calendar to prevent the spread of COVID-19 infection and to achieve 70% inoculation for the Saudi population. This study assesses the impact of extended e-learning and other associated stressors on the emotional health of university students in Saudi Arabia. An online cross-sectional survey collected data between the months of January–March 2021. The emotional signs of stress were measured by using a subset of items from the COVID-19 Adolescent Symptom and Psychological Experience Questionnaire (CASPE). Data about demographic variables, educational characteristics and academic performance were also collected. A regression analysis was performed to determine predictors of emotional health. A total of 434 university students including females (63%) and males (37%) provided responses. One-third of students (33%) indicated that the COVID-19 pandemic and its resulting changes including online distance studies greatly influenced their daily lives in a negative way. The regression analysis demonstrated that female students and students with average academic performance had increased vulnerability to experience emotional signs of stress (p < 0.05). The factors ‘Not going to university’ and ‘Not having a routine life’ were significant predictors of stress responses (p < 0.01) and (p < 0.001) respectively. E-learning during the COVID-19 pandemic made it possible for students to complete their studies as per academic calendar; simultaneously, it increased the vulnerability to experience stress, particularly for female students and students with average academic performance. These findings imply that academic advising and counseling services should be more readily available during digital studies to support at risk students.

Background: Visual discomfort or asthenopia is presented through unpleasant somatic and perceptual symptoms including headaches, fatigue, light sensitivity, blurred text, diplopia, movement of letters, and fading and impaired reading performance. Its etiology can be prolonged exposure to near work tasks such as reading or computer use. The American Academy of Ophthalmology, American Association for Pediatric Ophthalmology and Strabismus stated that vision problems could negatively affect learning. Objectives: To measure the prevalence of visual discomfort among the medical students at King Abdulaziz University (KAU) and evaluate its effect on their academic performance. Methods: This cross-sectional study was conducted in 2018 at KAU in the city of Jeddah, Saudi Arabia with 417 medical students. The data were collected using an electronic questionnaire that was sent to their phone numbers. The statistical analyses were done using the statistical package for social sciences (SPSS) software version 21. Results: The visual discomfort symptom scores demonstrated that 87% of the participants scored low, while 12.2% scored moderately; none of the participants scored high. We did not find any significant relationship between visual discomfort and students' cumulative GPA or GPA of the last semester. We noted that the most common visual discomfort symptoms were associated with reading and light sensitivity. Conclusion: This study demonstrated that visual discomfort symptoms did not affect the cumulative or last semester GPA.

To investigate the refractive and non-strabismic binocular vision status of Optometry students in University of Cape Coast, Ghana and to establish any associations between these conditions. A cross sectional study of 105 Optometry students were taken through a comprehensive optometric examination to investigate the refractive and non-strabismic binocular vision status. Fisher’s exact test (IBM SPSS version 21) was used to assess association between these conditions. Prevalence of refractive error and non-strabismic binocular vision dysfunctions were 59.0% and 34.3% respectively. Prevalence of specific refractive errors were 17.1% myopia, 19.0% hyperopia and 22.9% astigmatism. Non-strabismic accommodative and vergence dysfunctions were found to be 21.9% and 12.4% respectively. Specific types of accommodative and vergence disorders were as follows: accommodative fatigue (8.6%), accommodative infacility (6.7%), accommodative insufficiency (4.7%) and accommodative excess (1.9%), convergence insufficiency (1.9%), convergence excess (1.0%), divergence insufficiency (2.9%), basic exophoria (1.9%), and basic esophoria (4.7%). There was a significant association between refractive errors in general and accommodative fatigue (p = 0.030) and between myopia and accommodative excess (p= 0.028). It is critical that potential primary eye care practitioners become aware of their refractive and non-strabismic binocular vision status.Journal of Medical and Biomedical Sciences (2016) 5(2), 24-29
