Number of people with glaucoma worldwide.
TLDR
Improved methods of screening and therapy for glaucoma are urgently needed, as it is the second leading cause of vision loss in the world.Abstract:
AIM: To estimate the prevalence of glaucoma among people worldwide. METHODS: Available published data on glaucoma prevalence were reviewed to determine the relation of open angle and angle closure glaucoma with age in people of European, African, and Asian origin. A comparison was made with estimated world population data for the year 2000. RESULTS: The number of people with primary glaucoma in the world by the year 2000 is estimated at nearly 66.8 million, with 6.7 million suffering from bilateral blindness. In developed countries, fewer than 50% of those with glaucoma are aware of their disease. In the developing world, the rate of known disease is even lower. CONCLUSIONS: Glaucoma is the second leading cause of vision loss in the world. Improved methods of screening and therapy for glaucoma are urgently needed.read more

The number of people with glaucoma worldwide in 2010 and 2020
Harry A. Quigley,Aimee T. Broman +1 more
TL;DR: Glaucoma is the second leading cause of blindness worldwide, disproportionately affecting women and Asians, and it 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.

Global prevalence of glaucoma and projections of glaucoma burden through 2040: a systematic review and meta-analysis.
TL;DR: The global prevalence of primary open-angle glaucoma (POAG) and primary angle-closure glauComa (PACG) and the number of affected people in 2020 and 2040 are examined, disproportionally affecting people residing in Asia and Africa.

The Ocular Hypertension Treatment Study: A Randomized Trial Determines That Topical Ocular Hypotensive Medication Delays or Prevents the Onset of Primary Open-Angle Glaucoma
Michael A. Kass,Dale K. Heuer,Eve J. Higginbotham,Chris A. Johnson,John L. Keltner,J. Philip Miller,Richard K. Parrish,M. Roy Wilson,Mae O. Gordon +8 more
TL;DR: Topical ocular hypotensive medication was effective in delaying or preventing the onset of POAG in individuals with elevated IOP, and clinicians should consider initiating treatment for individuals with ocular hypertension who are at moderate or high risk for developing POAG.
Journal ArticleDOI
The definition and classification of glaucoma in prevalence surveys
TL;DR: This review describes a scheme for diagnosis of glaucoma in population based prevalence surveys that makes provision for diagnosing glauca in eyes with severe visual loss where formal field testing is impractical, and for blind eyes in which the optic disc cannot be seen because of media opacities.
Journal ArticleDOI
Primary open-angle glaucoma.
Robert N. Weinreb,Peng T. Khaw +1 more
TL;DR: Improvements in therapy consist of more effective and better-tolerated drugs to lower intraocular pressure, and more effective surgical procedures to directly treat and protect the retinal ganglion cells that are damaged in glaucoma.

TL;DR: This monograph presents the detailed protocols and record forms for screening and diagnostic examinations, definitions of the specific abnormalities and characteristics used to screen for each disease, criteria for suspicion and diagnosis of diseases, detailed tables of the basic data from the study, evaluation of quality of the data, and discussion of selected findings.

TL;DR: Black Americans are at higher risk of primary open-angle glaucoma than their white neighbors, which may reflect an underlying genetic susceptibility to this disease and indicates that additional efforts are needed to identify and treat this sight-threatening disorder in high-risk communities.

TL;DR: Results confirmed that IOP is an important factor in glaucoma, but did not support the traditional distinction between "normal" and "elevated" pressure, nor its corollaries, "low-tension" glau coma and "high-tensions" glAUcoma.

TL;DR: The prevalence of open-angle glaucoma in Beaver Dam is similar to that in other white populations, and findings from this study re-emphasize the notion that estimates of glauca prevalence should be based on assessing multiple risk indicators.

TL;DR: The pattern of blindness in urban Baltimore appears to be different among blacks and whites, with Whites are far more likely to have age-related macular degeneration, and blacks to have primary open-angle glaucoma.
