1. Congenital glaucoma
2. Primary glaucoma
3. Secondary glaucoma
What are the 3 MAJOR types of glaucoma?
Narrow angle
Wide angle
What are the 2 types of primary glaucoma?
Congenital glaucoma
with this kind of glaucoma surgery is always required.
A disease of the eye in which the pressure of fluid inside the eyeball is abnormally high, caused by obstructed outflow of the fluid.
Define glaucoma.
glaucoma
A disease of the eye in which the pressure of fluid inside the eyeball is abnormally high, caused by obstructed outflow of the fluid.
Narrow angle
aka acute congestive
Narrow angle
cause: poor drainage because of the position of the iris. May see blurred vision, perhaps on one side, or headache.
chiefly pupil constrictors
eventually may be treated with surgery
What is the drug treatment for narrow angled glaucoma?
narrow angled glaucoma
chiefly pupil constrictors
eventually may be treated with surgery
Wide angle
most common kind of glaucoma
Wide angle
aka chronic simple
Wide angle
cause: poor drainage most probably due to abnormal blood vessel permeability
Wide angle
Which type of glaucoma need permanent drug therapy?
Wide angle
permanent drug therapy
pupil constriction often helps drainage
use drugs to decrease aqueous humor formation
permanent drug therapy
pupil constriction often helps drainage
use drugs to decrease aqueous humor formation
What is the drug therapy for wide angle glaucoma?
Miotics
What is the name of the drug group that constricts the pupil?
Cholinergic drugs
What are the miotic drugs called?
Miotics (cholinergic)
Therapeutic uses

Both narrow and wide angle primary glaucoma, especially critical in narrow angle

Helps two ways:
Contracts sphincters of iris
vasodilation of vessels draining eye
Therapeutic uses

Both narrow and wide angle primary glaucoma, especially critical in narrow angle

Helps two ways:
Contracts sphincters of iris
vasodilation of vessels draining eye
What are the therapeutic uses of miotic drugs?
Miotics
(cholinergics)
Side effects
what drug?

Spasms of ciliary muscle (blurred far vision)

Usually not bothered by other cholinergic side effects, but can get headache, salivation, sweating, diarrhea, increased asthma attacks, decreased BP.
driving at night
What is the caution for taking miotic drugs?
Carbonic Anhyrase inhibitors
Adrenergic drugs
Timolol maleate (like B-blockers)
Osmotic diuretics
What are the drugs that are used to reduce the fluid formation?
Carbonic Anhyrase inhibitors
inhibits one enzyme required for production of aqueous humor

what drug?
glaucoma
What are the therapeutic uses for Carbonic Anhydrase inhibitors?
Carbonic Anhyrase inhibitors
What drug?

Side effect

watch for cross-allergy in patients allergic to sulfa drugs

neurological effects possible including:
1. tingling in the extremities, lips, and anus
2. long-term, flaccid paralysis
3. convulsions
teratogenic in first trimester of pregnancy
What is the caution for Carbonic Anhyrase inhibitors?
Carbonic Anhyrase inhibitors

caution
teratogenic in first trimester of pregnancy
Adrenergic drugs
Therapeutic uses

1. wide angle primary glaucoma
2. glaucoma secondary to inflammation; given only after pupil constrictor (cholinergic agent) to counteract pupil dilatory effect.

*** act chiefly to decrease formation of aqueous humor
Adrenergic drugs
What is the name of the drug with the caution of narrow angle glaucoma, because the dilate the pupil?
narrow angle glaucoma
Name the caution that goes with taking adrenergic agents to reduce fluid formation.
