Asians have the highest prevalence of PACG.[33–35] Furthermore, a population-based study by Quigley et al. reported that 0.1% of their Hispanic population were affected with PACG. However, it has been speculated that angle closure might be more common among Hispanic individuals in the Western Hemisphere because of their linked heritage to migrants from Asia during the last Ice Age. Sakata K et al. found that PACG was more common among south Brazilians (Hispanic) than in European populations, and the adjusted prevalence of PACG observed in the study suggested that the prevalence of this disease in non-Asian, such as Hispanic, populations may be greater than has been traditionally believed and that most cases are asymptomatic. Interestingly, in our study, the highest LP was recorded in the White group and the lowest measurement was recorded in the Hispanic group. In Whites, these findings are consistent with the low rate of PACG in this group.
