glaucoma - Diseases of the eye in which the optic
nerve is damaged, usually slowly but progressively, by a level
of pressure in the eye which interferes with the normal blood
flow to the nerve. Most cases are called chronic simple glaucoma.
This glaucoma is usually painless,
and the vision loss is very subtly progressive so that a person
with it is unaware of any problem without an eye exam.
The vision loss is permanent
so it is vital that eye exams be regular in adults. Eye exams
by an ophthalmologist for glaucoma include pressure measurement,
evaluation of the optic nerve, and peripheral visual field checkup.
Treatment is usually quite successful with drops, laser or surgery.
glaucoma and
pain - A type of glaucoma
called narrow angle glaucoma can cause intense pain with a sudden
pressure rise. Such pain is uncomfortable but may be a helpful
warning that a serious condition exists. This "attack"
can usually be broken and then be treated with a laser for long
term protection.
