Knowledge, Attitudes, and Practices of Optometrists Regarding Low Vision Services in Saudi Arabia

Purpose:

To address the human resources challenge for the provision of low vision services in Saudi Arabia, this study sought to investigate the knowledge, attitudes, and practices of optometrists in Saudi Arabia regarding low vision services. The knowledge and attitudes to low vision services can influence the provision of low vision services by optometrists.

Methods:

A prospective cross-sectional survey of optometrists practicing in Saudi Arabia was undertaken using an online questionnaire designed to elicit the opinions of respondents. The online questionnaire was sent out to optometrists on the official mailing list of registered optometrists and those on the mailing list of the Saudi Society of Optometry.

Results:

Only 26.5% of the respondents correctly indicated the correct designation of low vision in terms of visual acuity. Although 95.8% indicated that optical low vision devices could help people with low vision, 81.6% reported that low vision devices were expensive, and 42.9% felt low vision practice was not profitable. Only 10.4% of respondents provide low vision services in their practice. Insufficient training in low vision care was the main barrier militating against the provision of low vision services.

Conclusion:

The pertinent finding in this study is that about a quarter of the respondents could correctly designate low vision in terms of visual acuity using the World Health Organization (WHO) definition. The study concluded that there was poor knowledge, attitudes, and practices of optometrists in Saudi Arabia regarding low vision, which has implications for the provision of low vision services by optometrists.

Prevalence of Refractive Errors among Children in Saudi Arabia: A Systemic Review

Introduction:

The aim of this review was to estimate the prevalence of refractive errors (RE) and uncorrected refractive error (URE) in school-aged children of 4 to 14 years of age in Saudi Arabia.

Methods:

An extensive search was performed for peer-reviewed studies with data from the Saudi population during the past 20 years. The Cochrane Library, Pubmed, and Embase databases were used. Two independent reviewers evaluated publications and extracted the data. The quality of the studies was evaluated based on a critical appraisal tool designed for systematic reviews. The pooled prevalence of refractive error, uncorrected refractive error and different types of refractive error were estimated by using the random-effects meta-analysis.

Results and Discussion:

Eight school-based studies were included in this review. Among the overall pooled population of 12,247childern, the estimated prevalence of refractive error was 17.5% (95% CI: 11.1- 25). In the five studies that reported uncorrected refractive error (N=10,198), the pooled prevalence was 16.8% (95% CI: 11.4 – 21.3). The overall prevalence of refractive errors was very similar among boys, 16.8 (95% CI: 10.8- 24.1), and girls, 17.7% (95% CI: 10.2 – 25.9). Myopia was the most prevalent refractive error and was present in 40.8% (95% CI: 16.1 – 69.9) followed by astigmatism 29.7% (95% CI: 6.1- 61.7) and hyperopia 28.3% (95% CI: 16.9 – 41.2).

Conclusion:

This review highlights the high prevalence of refractive errors and uncorrected refractive error among children in Saudi Arabia. More studies are required using standardised methods in different regions where there is a lack of information on UREs. It is recommended that vision screening programs of children for RE should be implemented at the community level and integrated into school health programmes in order to detect UREs and prevent amblyopia, which is one of the debilitating consequences of URE.
