Background: Visual impairment is disproportionately distributed between rural and urban dwellers. Rural dwellers have limited access to the eye care services that are available in urban cities.Aim: The aim of this study was to determine the prevalence and causes of visual impairment in Dariyah, a rural community in the Qassim region, Saudi Arabia.Setting: This research comprised a population-based assessment of the vision and visual status of the inhabitants of Dariyah community.Methods: A cross-sectional descriptive study was conducted amongst the inhabitants of the community of Dariyah. A comprehensive eye examination consisting of visual acuity, ocular health examination, objective and subjective refraction was performed. The examinations were conducted by registered ophthalmologists and optometrists from the Qassim University. Vision impairments were categorised according to the International Classification of Diseases (ICD), Section 9D90, ‘Vision impairment including blindness’ (2018).Results: In all, 68 (24.5%) participants had vision impairment (using the better-seeing eye), with refractive errors being the main cause of vision impairment. Other causes of vision impairment included cataract (20, 7.2%), trichiasis (5, 1.8%) and glaucoma (2, 0.7%). Refractive errors were present in 193 (69.7%), with astigmatism being the commonest refractive error. About 60% of those with refractive errors presented without spectacles for correction, and 20% reported that they had never had an eye examination. Refractive errors could not be determined in 19 (6.9%) of the subjects because of conditions such as matured cataract and other ocular abnormalities.Conclusion: Uncorrected refractive error was found to be the leading cause of vision impairment in this rural community in Saudi Arabia.

Aim: The purpose of this study was to determine the changes in the relative peripheral refractive error produced by soft single vision contact lenses in myopic schoolchildren. Methods: 27 myopic schoolchildren aged between 13 to 15 years were included in this study. The measurements of central and peripheral refraction were made only on the right eye using a Grand-Seiko WR-5100K open-field autorefractometer without contact lens (WL), and with wearing single vision contact lens (SVCL). Refractive power was measured at center and horizontal eccentricity between 35° temporal to 35° nasal visual field (in 5° steps). Results: SVCL showed an increase in peripheral hyperopic defocus at the nasal and temporal visual field compare with baseline, but this change was not statistically significant (p=0.129). Conclusion: Wearing single vision soft contact lenses increases the relative peripheral hyperopic defocus in myopic schoolchildren.

Background: Undiagnosed astigmatism among children may result in multiple unfavourable consequences, such as poor performance on cognitive and language tasks, reduced oral reading fluency, behavioural disorders, and amblyopia development. In contrast, astigmatism is easily correctable in young children, which highlights the need for periodic assessment of its prevalence amongpediatric populations. Purpose: This study aimed to assess the prevalence of astigmatism among the pediatric population in Jeddah, Saudi Arabia, and to assess the rate of newly detected cases (incidental astigmatism) and the associated risk factors. Patients and methods: This cross-sectional study was conducted among visitors of the awareness campaign about amblyopia, which took place in the Red Sea Mall, Jeddah, Saudi Arabia, on January 29–30, 2016. Children aged 2–15 years were enrolled in the study to undergo noncycloplegic eye examination using an autorefractometer for measuring cylindrical refractive error (Cyl). The calculated sample size for the studied age group of the population of Jeddah, Saudi Arabia was 291. Astigmatism was defined as Cyl 1 diopter in either eye. Multivariate binomial regression was used to analyze the predictors of incidental astigmatism. Results: We examined the eyes of 347 children, mean age = 7.788 (standard deviation = 2.69) years, females = 53.3%. The overall prevalence of astigmatism was 41.5%, whereas the prevalence of incidental astigmatism was 40.6% among 342 children without apparent astigmatism. The prevalence of incidental astigmatism was associated with a previous diagnosis of amblyopia, having a sibling known to have amblyopia, and wearing spectacles. However, only wearing spectacles was shown to predict incidental astigmatism in the multivariate analysis. Conclusion: Astigmatism is highly prevalent among children in Western Saudi Arabia, with the majority being undiagnosed before this screening campaign. These findings urge for further nationwide, population-based studies to address the burden of refractive errors among children in Saudi Arabia.

Background: Contact lenses are commonly worn by young population for many purposes such as vision correction, cosmetic causes and as a fashion trend. Although wearing contact lens is safe and does not require expertise but it can cause serious eye infections and corneal ulcers, sometimes resulting into loss of vision. The study is designed to com-pare and observe the contact lens hygiene compliance and self-management behavior with a focus on the contact lens wearing habits, cleaning and maintenance of contact lens by different methods and self-prescription between the medical and non-medical students of the Saudi Arabia. Methods: Five hundred young contact lens wearers with an average age of 18-22 years were selected conveniently from the student population of Princess Nourah Bint Abdulrahman University, Riyadh. After taking informed consent from the participants, their level of contact lens hygiene compliance and self-management was assessed by using a peer-reviewed questionnaire. Results: The mean (±SD) age of the participants was 20.87± 1.696 years. Out of 500 students 37.8% were medical and 62.2% were non-medical students. 56% students were wearing contact lens for the cosmetic reasons while 43.6% students were using it for the correction of their myopic refractive error. Most of the students were using daily wear soft contact lenses (96.6%) by self-prescription (51.4%) and majority of them were buying them from general retail store (83.6%) instead of some proper optician. The self-management behavior was statistically significant among nonmedical students (p=0.026). There was no significant difference between the two groups regarding the compliance of the contact lens hygiene but the knowledge and awareness about the risks and complications was statistically high in the medical students (p= 0.028). Most of the students in our study had rated them as an average wearer. Conclusion: This study concludes that self-management with the contact lens use is very common among the nonmedical students of Saudi Arabia. Although they are good in the lens hygiene compliance but their knowledge about the risks and complications of contact lens use and the lens care accessories was significantly low.
