Timolol maleate
like beta blockers

to reduce fluid formation
Timolol maleate
Name the drug

decrease fluid production (exact mechanism unknown)
does not change size of pupil (no interference night vision)
one dose can be effective for 24 hours
Timolol maleate
Name the drug

one dose can be effective for 24 hours
wide angle glaucoma
What are therapeutic uses for Timolol maleate
asthma
heart disease (heart block, heart failure)
What are the cautions for Timolol maleate?
Osmotic diuretics
for short use
orally or parentarally
acute attacks, preoperative use
removes trapped fluid from the eye, decreasing pressure
removes trapped fluid from the eye, decreasing pressure
Osmotic diuretics (mechanism of action)?
Mydriatics
What is another name for drugs that dilate the pupil?
Anticholinergic drugs
Adrenergic drugs
What are the mydriatic (pupil dilators)drug?
Anticholinergic drugs
Longer lasting than the adrenergic drugs to dilate pupils. What drug?
Anticholinergic drugs
Therapeutic uses

1. rest intraocular muscles and relieve pain of inflammation (cornea, ciliary muscle, iris, etc)

2. eye exam - accurately measure refractive index

3. pre- and post- op for intraocular surgery.
Therapeutic uses

1. rest intraocular muscles and relieve pain of inflammation (cornea, ciliary muscle, iris, etc)

2. eye exam - accurately measure refractive index

3. pre- and post- op for intraocular surgery.
What are the therapeutic uses for anticholinergic drugs for the purpose of dilating the pupil?
Anticholinergic drugs
what drug?
side effects
serious if systemically absorbed

dry mouth
tachycardia
fever (reduced sweating)
narrow angle glaucoma - can precipitate acute attack; effects may last up to four weeks.
What is the caution for using anticholinergic drugs?
Adrenergic drugs
Drug that dilates and reduces fluid formation.
Adrenergic drugs
Therapeutic uses:

1. wide angle and secondary glaucoma as stated above
(not because of dilation, however)

2. ocular exam (due to dilation - acts for short duration)
3. relieve congestion (constriction of conjunctivals blood vessels)
1. patients with cardiovascular disease (throw into heart failure)
2. narrow angle glaucoma
What are the cautions for taking adrenergic drugs to dilate pupils?
Antiinfectives
Steroids
Local anesthetics
What drugs are used to treat ocular injuries, infection, and inflammation?
Antiinfectives
Cautions systemically

1. may make patient sensitive to antiinfective that may be used again
2. may develop resistant strains of organisms
Antiinfectives
1. local sensitivity may develop (eye inflammation)
2. normal flora interfered with so may encourage abnormal organisms.
eye infections and inflammation
What are the therapeutic uses of antiinfectives?
1. allergic reaction of eye
2. severe injury
3. non-pus producing inflammations (i.e. chemical cause of irritant)
What are the therapeutic uses for steroids?
therapeutic uses for steroids
1. allergic reaction of eye
2. severe injury
3. non-pus producing inflammations (i.e. chemical cause of irritant)
1. reduces scarring and impaired vision
2. reduced inflammation helps prevent proteins and blood cells from entering aqueous humor (would decrease intraocular pressure)
What is the mechanism of action for steroids to treat ocular inflammations, infections, and injuries?
steroids
1. reduces scarring and impaired vision
2. reduced inflammation helps prevent proteins and blood cells from entering aqueous humor (would decrease intraocular pressure)
Steroids
Cautions
1. ***pus-producing inflammation
2. Prolonged therapy - can cause:
- secondary glaucoma
- cataracts ***
Local anesthetics
for pain

Caution: no-blink reflex - protect eye from drying out
