Prevalence of congenital red-green color vision defects in Arab boys from Riyadh, Saudi Arabia
1Dept. Optometry, King Saud University, Riyadh, Saudi Arabia.
Insights
Congenital red-green color vision defects (CVDS) affect 2.93% of Arab boys in Riyadh. This study confirms a low prevalence of these inherited vision conditions in Saudi Arabian males.
Area of Science:
- Ophthalmology
- Genetics
- Public Health
Background:
- Congenital color vision defects (CVDS) exhibit variations across different ethnicities and genders.
- Previous research suggests a low prevalence of red-green CVDS in Arab populations.
Purpose of the Study:
- To determine the prevalence of congenital red-green color vision defects (CVDS) in a cohort of Arab boys in Riyadh, Saudi Arabia.
- To characterize the types of red-green CVDS observed in the study population.
Main Methods:
- Screening of congenital red-green color vision defects (CVDS) was conducted among Arab boys in Riyadh.
- Standardized visual screening tools, including the Ishihara plates and the D 15 test, were utilized.
Main Results:
- The overall prevalence of congenital red-green color vision defects (CVDS) was found to be 2.93%.
- Deutan defects were the most common type, occurring in 1.95% of subjects.
- Protan defects (0.49%) and unclassified color defects (0.49%) were also identified.
Conclusions:
- The prevalence of congenital red-green CVDS in Arab boys from Riyadh aligns with previously reported low rates in adult males from central Saudi Arabia.
- These findings contribute to understanding the demographic variations in color vision deficiencies.
Abstract:
The prevalence of congenital red-green color vision defects (CVDS) is both racial and gender dependent. Red-green color vision defects (CVDS) have been screened for among Arab boys from Riyadh, Saudi Arabia, by using both the Ishihara plates and the D 15 test. The results indicate a prevalence of 2.93%. Deutan defect was present in 1.95% of the subjects, protan defect in 0.49% and unclassified color defect in 0.49%. This result confirms the previously reported low prevalence of congenital red-green CVDS among adult Arab males from the central region of Saudi Arabia.
