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 |

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.
