Which of the following ophthalmic medications is a nonselective beta-blocker used to lower intraocular pressure?
Timolol
Pilocarpine
Latanoprost
Brinzolamide
Timolol is a nonselective beta-blocker commonly used topically to decrease aqueous humor production and lower intraocular pressure. Pilocarpine is a cholinergic agonist, latanoprost is a prostaglandin analog, and brinzolamide is a carbonic anhydrase inhibitor.
Latanoprost lowers intraocular pressure primarily by which mechanism?
Increasing uveoscleral outflow
Inhibiting carbonic anhydrase
Decreasing aqueous humor production
Blocking alpha receptors
Latanoprost is a prostaglandin F2α analog that increases the uveoscleral outflow of aqueous humor to reduce intraocular pressure. It does not primarily decrease production, block alpha receptors, or inhibit carbonic anhydrase.
Which class of ophthalmic drug does dorzolamide belong to?
Beta-blocker
Carbonic anhydrase inhibitor
Prostaglandin analog
Alpha agonist
Dorzolamide is a topical carbonic anhydrase inhibitor that reduces aqueous humor production, thereby lowering intraocular pressure. It is not a beta-blocker, alpha agonist, or prostaglandin analog.
Pilocarpine eye drops reduce intraocular pressure by which action?
Inhibiting carbonic anhydrase in the ciliary body
Stimulating muscarinic receptors to constrict the pupil
Blocking beta receptors to decrease humor production
Increasing uveoscleral outflow
Pilocarpine is a muscarinic agonist that induces miosis and contraction of the ciliary muscle, increasing trabecular outflow of aqueous humor. It does not block beta receptors, inhibit carbonic anhydrase, or increase uveoscleral outflow.
Moxifloxacin ophthalmic solution is part of which antibiotic class?
Sulfonamides
Aminoglycosides
Macrolides
Fluoroquinolones
Moxifloxacin is a fourth-generation fluoroquinolone antibiotic used topically in the eye for bacterial infections. It does not belong to macrolides, aminoglycosides, or sulfonamides.
What is the recommended dosing frequency for latanoprost ophthalmic drops?
Every four hours
Twice daily in the morning and evening
Once daily in the evening
Every two hours while awake
Latanoprost is typically dosed once daily in the evening to maximize its effect on uveoscleral outflow. More frequent dosing does not increase efficacy and may increase side effects.
After instilling one topical ophthalmic medication, how long should a patient wait before applying a second drop of a different medication?
Immediately after the first
At least 5 minutes
1 hour
30 seconds
Waiting at least five minutes between different ophthalmic drops allows adequate absorption and reduces washout of the first medication. Shorter intervals may dilute the first drop, and longer intervals are unnecessary.
Topical atropine eye drops are contraindicated in which condition?
Dry eye syndrome
Macular degeneration
Diabetic retinopathy
Narrow-angle glaucoma
Atropine causes pupil dilation which can precipitate acute angle-closure in patients with narrow anterior chamber angles. It is not specifically contraindicated in diabetic retinopathy, dry eye, or macular degeneration.
Which administration technique helps reduce systemic absorption of topical eye drops?
Punctal occlusion
Shaking the bottle vigorously
Using more than one drop at once
Applying pressure above the eyebrow
Punctal occlusion involves gently pressing on the nasolacrimal duct after drop instillation, reducing drainage into the systemic circulation. Shaking, eyebrow pressure, or multiple drops do not effectively limit systemic absorption.
Which systemic side effect is most commonly associated with topical timolol?
Bradycardia
Hyperglycemia
Tachycardia
Hypertension
Topical timolol can be systemically absorbed and act like an oral beta-blocker, leading to bradycardia. It does not typically cause hyperglycemia, tachycardia, or hypertension.
A common ocular side effect of prostaglandin analogs is:
Increased iris pigmentation
Dry eye syndrome
Keratitis
Lens opacification
Prostaglandin analogs like latanoprost can cause increased melanin deposition in the iris, leading to darker eye color. They are not typically associated with dry eye, keratitis, or lens opacification.
After instilling an eye drop, how long should a patient ideally keep their eyes gently closed?
1-2 minutes
10 seconds
Immediately open the eye
30 minutes
Keeping the eyes gently closed for one to two minutes after instillation increases contact time and absorption of the medication. Shorter or immediate opening can reduce efficacy, and much longer is unnecessary.
What is the first-line systemic medication to lower intraocular pressure in acute angle-closure glaucoma before definitive treatment?
Acetazolamide
Latanoprost
Pilocarpine
Timolol
Acetazolamide, a systemic carbonic anhydrase inhibitor, rapidly reduces aqueous humor production and is used in acute angle-closure before laser or surgical intervention. Pilocarpine is less effective initially, and latanoprost or timolol are not systemic first-line agents in this emergency.
Brimonidine lowers intraocular pressure primarily by which mechanism?
Cholinergic stimulation widening trabecular meshwork
Beta-adrenergic blockade increasing outflow
Alpha-2 adrenergic receptor agonism reducing aqueous production
Inhibition of prostaglandin synthesis
Brimonidine is an alpha-2 agonist that decreases aqueous humor production and may also increase uveoscleral outflow. It does not act via beta blockade, cholinergic stimulation, or prostaglandin inhibition.
What is the typical dosing frequency for brimonidine tartrate ophthalmic drops?
Twice daily
Every hour
Three times daily
Once daily
Brimonidine tartrate eye drops are commonly dosed three times daily to maintain consistent intraocular pressure reduction. Once or twice daily dosing is generally insufficient, and hourly dosing is unnecessary and may increase side effects.
In which systemic condition is the use of topical timolol contraindicated due to risk of exacerbation?
Asthma
Hyperthyroidism
Osteoarthritis
Gastroesophageal reflux
Topical timolol can be systemically absorbed and worsen bronchoconstriction in patients with asthma. It is not specifically contraindicated in osteoarthritis, hyperthyroidism, or GERD.
Which intraocular pressure - lowering agent is preferred in uveitic glaucoma to minimize risk of exacerbating intraocular inflammation?
Pilocarpine
Latanoprost
Dorzolamide
Brimonidine
Carbonic anhydrase inhibitors like dorzolamide reduce aqueous production without promoting inflammation, making them suitable for uveitic glaucoma. Prostaglandin analogs can exacerbate inflammation, and miotics or alpha agonists may be less appropriate in this context.
What is the underlying mechanism of increased iris pigmentation observed in patients using latanoprost?
Deposition of drug metabolites in the stroma
Degeneration of iris epithelial cells
Enhanced vascular perfusion of the iris
Increased melanin synthesis in iris melanocytes
Latanoprost stimulates melanogenesis in iris melanocytes, leading to increased pigmentation. It does not deposit drug metabolites, cause epithelial degeneration, or alter iris perfusion to produce this effect.
For optimal reduction of systemic absorption after eye drop instillation, how long should a patient apply punctal occlusion?
10 seconds
2 minutes
5 minutes
30 seconds
Applying gentle pressure over the puncta for about two minutes effectively blocks nasolacrimal drainage, minimizing systemic absorption. Shorter durations are less effective, and much longer time is unnecessary for most medications.
A patient on prednisolone acetate eye drops develops significant steroid-induced ocular hypertension. What is the best management strategy to continue anti-inflammatory therapy while minimizing pressure elevation?
Discontinue all anti-inflammatory therapy
Switch to loteprednol suspension
Increase prednisolone dose
Add a systemic corticosteroid
Loteprednol is a 'soft' corticosteroid designed to provide anti-inflammatory effects with lower risk of raising intraocular pressure. Increasing prednisolone or systemic steroids would worsen hypertension, and stopping all therapy risks uncontrolled inflammation.
