depend on the type
Types and pathophysiology of glaucoma
thus it is important
Close angle glaucoma
caused by blockage of the drainage canals
result in sudden rise in IOP
closed or narrow angle between the iris and cornea
develops rapidly
symptoms and damage are noticeable
requires immediate medical attention
Open angle glaucoma
caused by the slow blockage of the drainage canals
result in increased IOP
wide and open angle between the iris and cornea
develops slowly
symptoms and damage are not noticed
most common
other types
causes and risk factors of glaucoma
that lead to certain events
risk factors
genetics
age
some medical conditions
corticosteroid medications
eye injury
eye malformation
causes
blocked drainage
high blood pressure
medications
corticosteroids

Retina
optic nerve
optic chiasma
optic tract
lateral geniculate body
optic radiation
primary visual cortex

abnormalities result in
Aqueous humor
produced by ciliary processes
in the posterior chamber
flows around the lens though the pupil
in the anterior chamber
Trabecular meshwork
Schlemm's canal
collector channels

thus returning the structure back to normal
with good management the patient can live a normal life
