In this issue of JAMA Ophthalmology, Gracitelli et al1 raise more questions than answers, a few of which this Editorial will highlight. To summarize, the authors examined the longitudinal differences in perimetric testing in ancestry groups and determined that patients of African ancestry showed greater variability in visual field testing than individuals of European ancestry. As the authors noted, this finding and its underlying mathematical modeling suggests that delayed detection of progression of visual impairment may occur in patients of African descent. This delay may contribute to greater visual impairment in these patients compared with members of other ethnicities. Although one may draw a direct line between the differences noted between these groups and the conclusions of the authors, missing details beneath the surface raise questions that should be considered before settling on those conclusions.
