“…Ten studies included previously 1 were excluded, owing to: (1) no population based sample 38-40 ; (2) majority not visual field tested [41][42][43][44] ; or (3) IOP level used to define OAG. [45][46][47] Normal tension glaucoma and exfoliation syndrome were included as OAG.…”

Aim: To estimate the number of people with open angle (OAG) and angle closure glaucoma (ACG) in 2010 and 2020. Methods: A review of published data with use of prevalence models. Data from population based studies of age specific prevalence of OAG and ACG that satisfied standard definitions were used to construct prevalence models for OAG and ACG by age, sex, and ethnicity, weighting data proportional to sample size of each study. Models were combined with UN world population projections for 2010 and 2020 to derive the estimated number with glaucoma.Results: There will be 60.5 million people with OAG and ACG in 2010, increasing to 79.6 million by 2020, and of these, 74% will have OAG. Women will comprise 55% of OAG, 70% of ACG, and 59% of all glaucoma in 2010. Asians will represent 47% of those with glaucoma and 87% of those with ACG. Bilateral blindness will be present in 4.5 million people with OAG and 3.9 million people with ACG in 2010, rising to 5.9 and 5.3 million people in 2020, respectively. Conclusions: Glaucoma is the second leading cause of blindness worldwide, disproportionately affecting women and Asians. P ublic health planning requires accurate estimation of disease burden for major disorders. We previously estimated the number with open angle glaucoma (OAG) and angle closure glaucoma (ACG), 1 but since then, further surveys have appeared.2-25 In addition, a standardised definitional structure of OAG and ACG was proposed to compare prevalence in glaucoma studies. 26 We estimate the number with OAG and ACG for 2010 and 2020 using prevalence models constructed by age, sex, and ethnicity. METHODSAge and sex specific population projections by 5 year grouping of adults over age 40 years were obtained (http:// esa.un.org). We selected the dominant ethnic group for each of eight regions: (1) Middle East/North Africa group
