Purpose: Heightened public awareness about glaucoma may increase the chance
of identifying undetected cases. To ascertain determinants of glaucoma awa
reness, we surveyed a population visiting a general eye clinic,
Design: Cross-sectional study.
Participants: 1197 general eye clinic patients and their companions.
Methods: We designed and administered a questionnaire about glaucoma to gen
eral eye clinic patients and their companions. We created multivariate logi
stic regression models to ascertain the effect of demographic and clinical
features on the likelihood of being unaware of glaucoma.
Main Outcome Measures: Adjusted odds ratio (OR) with 95% confidence interva
ls of survery attributes associated with self-perceived unfamiliarity with
glaucoma.
Results: Glaucoma awareness overall (72%) approached that found in the subg
roup self-reporting a diagnosis of glaucoma (80%), Survey attributes associ
ated with an increased likelihood of being unaware of glaucoma were African
American race (OR = 1.69 [1.28-2,20], Hispanic ethnicity (OR = 2.13 [1.46-
3.02]), and less than a college education (OR = 1,67 [1,37-2,05]). Age was
also a determinant of glaucoma awareness (for ages 50-64 years, OR = 0.60 [
0.44-0.80] and for ages 65-79 years, OR = 0.56 [0.41-0.75] compared with ag
es less than 35 years). A self-report of glaucoma was not a determinant of
glaucoma awareness (OR = 0.63 [0,33-1,17]), although there was a trend towa
rd enhanced glaucoma awareness in this subgroup. Finally, respondents with
a history of employment in the health field (OR = 0.63 [0.49-0.82]) myopia
(OR = 0.68 [0,56-0.82]), glaucoma in a first-degree relative (OR = 0.68 [0.
53-0.87]), and respondents who reported having a dilated eye examination (O
R = 0.53 [0.42-0.66]) were less likely to be unaware of glaucoma than those
who did not have these attributes.
Conclusions: Although glaucoma awareness in this population was high, Hispa
nics, African Americans, and those with less than a college education were
more likely to be unfamiliar with the disease, Interestingly, a self-report
of having glaucoma was not a statistically significant determinant of glau
coma awareness. (C) 2000 by the American Academy of Ophthalmology.
