Genetics seems to be the reason that Hispanic kids are more likely to have astigmatism than African-American kids. Research shows that 17% of Hispanic children may exhibit astigmatism between the ages of 6 months and 6 years.
The good news is that children from all ethnic groups who show evidence of astigmatism in the first year of life tend to grow out of the condition. In the case of the Hispanic children in the study, only 5% had significant enough astigmatism to require corrective lenses.
As part of the Multi-Ethnic Pediatric Eye Disease Study, researchers have been tracking trends in vision conditions so that health practitioners have an idea of what to look for in their patients.
