Medications used in eye care including drops, ointments, and systemic drugs for various eye conditions.
Prostaglandin analogs (e.g., latanoprost), beta-blockers (e.g., timolol), alpha-agonists (e.g., brimonidine), carbonic anhydrase inhibitors (e.g., dorzolamide), and cholinergic agents (e.g., pilocarpine) are used to reduce intraocular pressure. |
| Think of drugs that 'push down' intraocular pressure |
| 2 | Which medication class is commonly used as the first-line treatment for bacterial conjunctivitis? | Topical antibiotics such as erythromycin ointment, sulfacetamide drops, or fluoroquinolones are used as first-line therapy. | Think 'antibiotics for bacterial infections' in the eye |
| 3 | Name a common topical corticosteroid used in managing ocular inflammation. | Prednisolone acetate is a commonly used topical corticosteroid for ocular inflammation. | Steroids 'reduce' inflammation and are administered as drops or ointments |
| 4 | What systemic medication is used in the treatment of uveitis? | Systemic corticosteroids (e.g., prednisone) are often used to control intraocular inflammation in uveitis. | Think of 'systemic steroids' for widespread inflammation |
| 5 | Which drug class is used to treat allergic conjunctivitis? | Antihistamines (e.g., olopatadine), mast cell stabilizers (e.g., cromolyn), and NSAID drops are used to treat allergic conjunctivitis. | Think 'allergy relief' for itchy, inflamed eyes |
| 6 | Name an ocular antihypertensive agent used in the management of glaucoma. | Timolol, a beta-blocker, is commonly used to decrease aqueous humor production and lower intraocular pressure. | Beta-blocker 'blocks' pressure buildup |
| 7 | Which medication is used topically to treat herpetic keratitis? | Trifluridine, an antiviral eye drop, is used to treat herpetic keratitis caused by herpes simplex virus. | Think 'viral treatment' for corneal infections |
| 8 | What systemic medication is used in age-related macular degeneration (AMD) with geographic atrophy? | No systemic medication has proven effective; management is mainly supportive. However, anti-VEGF injections are used in neovascular AMD. | Differentiate between dry and wet AMD treatments |
| 9 | Which drug is used as an antidote in cases of ocular poisoning with organophosphates? | Atropine sulfate is an antidote for organophosphate poisoning affecting the eye, but in systemic poisoning, pralidoxime is also used. | Remember 'antidote' for nerve agent-like poisoning |
| 10 | Name a common preservative used in ophthalmic drops and a concern associated with it. | Benzalkonium chloride (BAK) is a common preservative, but it can cause ocular surface toxicity with long-term use. | Think 'preservative' and 'toxicity' in chronic use |
| 11 | What is the main mechanism of action of prostaglandin analogs in glaucoma treatment? | They increase uveoscleral outflow of aqueous humor, thereby lowering intraocular pressure. | Prostaglandins 'push' fluid out via alternative pathways |
| 12 | Which topical medication is used to treat dry eye syndrome by increasing tear production? | Cyclosporine ophthalmic emulsion (e.g., Restasis) is used to increase tear production in dry eye syndrome. | Think 'immune modulation' in dry eyes |
| 13 | Name an oral medication used in the management of ocular cystinosis to reduce crystal accumulation. | Cysteamine oral solution is used to deplete cystine in cystinosis, which affects the eyes among other organs. | Cystine crystal reduction strategy |
| 14 | Which drug is used as a mydriatic agent during eye examinations or surgeries? | Tropicamide is a short-acting muscarinic antagonist used to dilate pupils. | Think 'dilate' with 'mydriatic' agents |
| 15 | What medication is used to prevent nausea and vomiting in patients with severe ocular pain or after eye surgery? | Prochlorperazine or ondansetron may be used to control nausea associated with ocular procedures. | Anti-emetics for procedure-related nausea |
| 16 | Which systemic drug is used in the treatment of central retinal artery occlusion to improve blood flow? | Intra-arterial thrombolytics or hyperbaric oxygen therapy may be considered, but there is no definitive systemic drug; management is primarily supportive. | Focus on emergent management strategies |
| 17 | What is the role of pilocarpine in ophthalmology? | Pilocarpine is a cholinergic agent that causes miosis and improves aqueous outflow in glaucoma, especially in primary narrow-angle glaucoma. | Think 'pupil constriction' to lower pressure |
| 18 | Which class of drugs is contraindicated in patients with a history of angle-closure glaucoma? | Mydriatic agents like atropine and tropicamide are contraindicated as they can precipitate acute angle-closure attacks. | Mydriatics 'close' the angle in susceptible eyes |
| 19 | Name a topical NSAID used in ophthalmology and its primary use. | Ketorolac eye drops are used to reduce inflammation and pain after ocular surgery or injury. | NSAID for 'pain and inflammation' control |
| 20 | What medication is used to treat herpetic stromal keratitis? | Oral acyclovir or valacyclovir are used to treat herpetic keratitis, often combined with topical steroids in stromal involvement. | Antiviral drugs target herpes virus |
