Glaucoma prevalence in Indigenous Australians.

摘要

AIM: Define the prevalence of glaucoma within the Indigenous Australian population. METHODS: Aboriginal and Torres Strait Islander adults aged >/= 40 years were recruited from 30 randomly selected sample areas or communities. Participants were regarded to have glaucoma if they had a cup:disc ratio (CDR) of > 0.8, or missed >/= 2 points on the Frequency Doubling Test and a CDR > 0.7 in at least one eye. RESULTS: 1189 eligible adult participants were examined, representing 72% of the target population. After excluding cases with missing or ungradable information, the authors found a 2.2% (95% CI 1.6% to 3.6%) overall prevalence of glaucoma. In univariate analyses, the odds of glaucoma increased with age (chi(2) trend=4.38, p < 0.001), male gender (OR 2.43, 95% CI 1.10 to 5.41), less than secondary education (OR 4.74, 95% CI 1.96 to 11.45) and self-reported history of glaucoma (OR 20.8; 95% CI 6.23 to 69.51). After a multivariate analysis, none of these attributes other than history of glaucoma remained significant. No cases of low vision (presenting visual acuity (VA) < 6/12 to
