We thank Dr Ekström for his interest in our study.1 Dr Ekström comments on the scarcity of population-based incidence data on glaucoma and contributes information on an older Swedish cohort where pseudoexfoliation is common. In addition to major differences in the ethnic composition, age range, sample size, and environmental exposures of the study populations in Sweden and Barbados, it is interesting to note the predominant type of glaucoma identified by each study. Of the 13 incident cases in the Swedish study, 3 had primary OAG, and the remaining 10 cases were diagnosed as exfoliation glaucoma. These results are in marked contrast to our report, which is based on 67 incident cases of primary OAG in a black population where exfoliation is extremely uncommon. Despite these major differences, both studies confirmed the high risks associated with IOP of 21 mm Hg or more.
