QuestionAnswer
What drugs are Ophthalmic Beta-Adrenergic Blockers? End in "-olol" Betaxolol, Carteolol, Levobunolol, Metipranolol, and Timolol
What is the action for ophthalmic Beta-Adrenergic Blockers and ophthalmic Carbonic Anhydrase Inhibitors? Reduce the production of aqueous humor
What are the indications for ophthalmic Beta-Adrenergic blockers and Ophthalmic Carbonic Anhydrase Inhibitors? Glaucoma: open angle & ocular hypertension.
What are the contraindications for Ophthalmic: Beta-Adrenergic Blockers, Carbonic Anhydrase Inhibitors, and Prostaglandin Agonists? Known allergy. Minimal system effects: blocks the SNS. Pregnancy Category C
What are the adverse effects for ophthalmic Beta-Adrenergic Blockers? Irritation: burning/stinging, blurred vision, lacrimation Minimal system absorption effects (blocks the SNS): may cause bradycardia, hypotension, & bronchoconstriction
What are the drug-drug interactions when using ophthalmic beta-adrenergic blockers? Space eye drops apart depending on meds. Allow time in between before administering other eye drops.
What drugs are classified as Ophthalmic Carbonic Anhydrase Inhibitors? End in "-zolamide" Brinzolamide and Dorzolamide

What drugs are classified as ophthalmic Prostaglandin Agonists? End in "-prost" Latanoprost, Tafluprost, Travoprost, and Bimatroprost
What is the action of ophth. Prostaglandin Agonists? Increase in uveoscleral outflow. Allows fluid to flow out of the eye

What are the adverse effects of ophthalmic Prostaglandin Agonists? Increase iris pigmentation (darkens eye color). Foreign body sensation & irritation (burning/stinging). Blurred vision
What are the overall indications for Ophthalmic Agents? Miotics: pupil constriction, decrease resistance to aqueous flow, and used for glaucoma. Mydriatics: pupil dilation & allows for retina exams. Cycloplegics: Paralyze muscle that controls the lens to aid refraction. Ophthalmic infections & inflammation.
What are the overall adverse effects of ophthalmic agents? Irritation, blurred vision, tearing, & headache.
List an implementation when administering opthalm. Beta-Adrenergic Blockers to prevent minimal system effects. Educate patient to apply pressure gently on the nasolacrimal duct for at least a minute to prevent system absorption.
List nursing dx for Ophthalmic Agents Acute pain r/t eye irritation & burning/stinging sensation Deficient knowledge related to drug therapy
What should you assess for prior to administering ophthalmic agents? Medical hx: Assess for drug allergy, current meds, and conditions. Physical: Perform an eye assessment & possibly a vision exam. Assess overall general eye condition.
What should you evaluate for when administering ophthalmic agents? Evaluate the drug's therapeutic effect/pt's response to the drug. Evaluate for adverse effects. Evaluate comfort & safety measures and effectiveness of the teaching plan.
