7 Questions
What is the mechanism of action of miotics in reducing IOP?
They increase aqueous outflow
Which drug is a direct-acting cholinergic used for specific types of glaucoma?
Pilocarpine
Which drug is a less potent miotic than pilocarpine and may cause systemic side effects?
Carbachol
Which class of drugs is the most cost-effective for reducing IOP?
Beta blockers
What percentage of IOP reduction do non-selective beta blockers provide?
25%
Which patients are contraindicated to use non-selective beta blockers for IOP reduction?
Patients with asthma or COPD
Which alpha2 agonist is highly selective and has neuroprotective effects?
Brimonidine
Study Notes
- Miotics reduce IOP by increasing aqueous outflow.
- Pilocarpine is a direct-acting cholinergic used for specific types of glaucoma.
- Carbachol is a less potent miotic than pilocarpine and may cause systemic side effects.
- Beta blockers are the most cost-effective agents for reducing IOP.
- Non-selective beta blockers provide 25% IOP reduction, but are contraindicated in patients with asthma, COPD and heart disease.
- Selective beta blockers predominantly block beta1 and have fewer emotional/CNS side effects.
- Alpha2 agonists decrease aqueous production and provide 20-25% IOP reduction.
- Apraclonidine is relatively selective and causes slight mydriasis in Horner's syndrome.
- Brimonidine is highly selective and has neuroprotective effects.
- Topiramate can cause angle closure glaucoma.
