Ophthalmic Medications Overview

Drugs Affecting Ocular Health

Types of Ophthalmic Medications
  • Latanoprost
    • Causes brown pigmentation on the iris.
    • Example of Prostaglandin agonist.
  • Tetracaine and Proparacaine
    • Examples of Ophthalmic Local Anesthetics.
  • Vidarabine
    • Example of Ophthalmic Anti-infectives.
  • Atropine
    • Example of Mydriatics (used to dilate pupils).
  • Timolol
    • Example of Beta blockers, used with caution in asthmatic patients.
  • Dipivefrin
    • Example of Sympathomimetics.
Effects and Considerations
  • Prolonged use of ophthalmic corticosteroids can lead to:
    • Delayed healing of wounds.
    • Corneal erosions.
  • Postoperative care: Patients should wear an eye patch after certain procedures due to loss of the blinking reflex caused by local anesthetics.
Ophthalmic Agents for Specific Conditions
  • Drugs decreasing aqueous humor production:
    • a) Beta blockers
    • b) Carbonic Anhydrase inhibitors
    • e) Sympathomimetics
  • Used in acute eye injuries:
    • Ophthalmic Corticosteroids help prevent scarring.
Storage and Dosage
  • Latanoprost must be refrigerated if not opened.
  • No antibiotic eye medications should be used for more than 10 Days to prevent opportunistic infections (e.g., fungi).
Medications to Manage Intraocular Pressure
  • Latanoprost is noted for causing the greatest decrease in intraocular pressure.
  • Alternatives for aqueous humor outflow increase:
    • a) Beta blockers
    • d) Prostaglandin agonists
    • e) Sympathomimetics
  • Miotics:
    • Example: Pilocarpine
    • Used in specific eye procedures but may not be suitable for patients with open-angle glaucoma.
Anti-Inflammatory Use
  • Ophthalmic NSAIDs:
    • Used for treating inflammation, especially postoperative inflammation post-cataract surgery.
    • Examples: Ketorolac, Diclofenac.
Miscellaneous
  • Acetazolamide:
    • Acts as both a diuretic and treatment for glaucoma.
  • Gentamicin:
    • Example of Ophthalmic Anti-infectives used for superficial infections.
  • Polymyxin B:
    • Another example of Ophthalmic Anti-infectives.
Summary of Key Agents
  • Beta blockers:
    • Example: Timolol, helps decrease aqueous humor production.
  • Carbonic Anhydrase inhibitors:
    • Examples: Dorzolamide, Acetazolamide.
  • Local Anesthetics:
    • Used for foreign body removal and painful injuries.
