Statistics by Country for Glaucoma

Prevalance of Glaucoma:

2,000,000 people are visually impaired by glaucoma in the US (Research to Prevent Blindness, NISE, NSF)

Prevalance Rate for Glaucoma:

approx 1 in 136 or 0.74% or 2 million people in USA [about data]

Extrapolation of Prevalence Rate of Glaucoma to Countries and Regions:

WARNING! EXTRAPOLATION ONLY! NOT BASED ON COUNTRY-SPECIFIC DATA SOURCES. The following table attempts to extrapolate the above prevalence rate for Glaucoma to the populations of various countries and regions. These prevalence extrapolations for Glaucoma are only estimates, based on applying the prevalence rates from the US (or a similar country) to the population of other countries, and therefore may have very limited relevance to the actual prevalence of Glaucoma in any region:

Undiagnosed prevalence of Glaucoma:

Undiagnosed Prevalence Rate for Glaucoma: approx 1 in 272 or 0.37% or 1 million people in USA [about data]

Extrapolation of Undiagnosed-Prevalence Rate for Glaucoma to Countries and Regions: The following table attempts to extrapolate the above undiagnosed-prevalence rate for Glaucoma to the populations of various countries and regions. As discussed above, these undiagnosed-prevalence extrapolations for Glaucoma are only estimates and may have limited relevance to the actual undiagnosed-prevalence of Glaucoma in any region:

About extrapolations of prevalence and incidence statistics for Glaucoma:

WARNING! EXTRAPOLATED STATISTICS ONLY! Not based on data sources from individual countries. These statistics are calculated extrapolations of various prevalence or incidence rates against the populations of a particular country or region. The statistics used for prevalence/incidence of Glaucoma are typically based on US, UK, Canadian or Australian prevalence or incidence statistics, which are then extrapolated using only the population of the other country. This extrapolation calculation is automated and does not take into account any genetic, cultural, environmental, social, racial or other differences across the various countries and regions for which the extrapolated Glaucoma statistics below refer to. The extrapolation does not use data sources or statistics about any country other than its population. As such, these extrapolations may be highly inaccurate (especially for developing or third-world countries) and only give a general indication (or even a meaningless indication) as to the actual prevalence or incidence of Glaucoma in that region. These statistics are presented only in the hope that they may be interesting to some people.

About prevalence and incidence statistics in general for Glaucoma:

The word 'prevalence' of Glaucoma usually means the estimated population of people who are managing Glaucoma at any given time (i.e. people with Glaucoma). The term 'incidence' of Glaucoma means the annual diagnosis rate, or the number of new cases of Glaucoma diagnosed each year (i.e. getting Glaucoma). Hence, these two statistics types can differ: a short disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence.
