INTRODUCTION
 Usually with a charecteristics loss of visual function.
 Damage to a optic nerve is irreversible prosses
 Usually caused by raised IOP acting on the nerve head
 Normal IOP is -15-21 mnn of hg
 It is a heterogenous group of diseases in whitch optic nerve
is damage.
 IOP is the most common risk factor for development of
glaucoma
 Vission loss is irreversible
 It is the secound leading causes of BLINDNESS.
 In its early stages it affects peripheral visual field only
but as it advances it affects central vision and results in
loss of visual acuity,
Intraocular pressure is not the only factor
responsible for glaucoma!
 95% of people with elevated IOP will never have the
damage associated with glaucoma.
 One-third of patients with glaucoma do not have
elevated IOP.
 Most of the ocular findings that occur in people
with glaucoma also occur in people without
glaucoma.
EPIDEMIOLOGY
 Globally estimated 8.4 million people who are blind on
the result of glaucoma
 These number are set to increases to 11.2 million by
2020
 It is the secound leading causes of BLINDNESS globally
 The highest prevelance of open angle glaucoma occures
in AFRICA.(WWW.SCIENCEDIRECT.COM)
 Global prevelance of glaucoma -2%of those over the age
of 40 years and 10% of those over 80 years of age
 Glaucoma blindness-
- global 8.0%
-india 12.8%
 Primary open-angle glaucoma (POAG) is the most
common type of glaucoma, accounting for over 70% of
cases.
 Ocular hypertension affects 3-5% of the population
over 40 years of age .
