Study Notes
Mydriatics and Miotics
- Mydriatics: drugs that dilate the pupil.
- Miotics: drugs that constrict the pupil.
Eyedrop Administration
- Wait 15 minutes between different eyedrops.
- Wait 5 minutes between multiple doses of the same eyedrop.
Cycloplegics
- Cycloplegics: drug class that paralyzes the ciliary body.
Cholinergic Drugs
- Indirect-acting and direct-acting cholinergics reduce intraocular pressure (IOP).
- Possible adverse effects: hypotension, bradycardia, tachycardia, headache, stomach problems, asthma attacks.
Sympathomimetics
- Sympathomimetics mimic epinephrine & norepinephrine, cause eye dilation, and reduce IOP.
- Local adverse effects: burning, pain, lacrimation.
- Rare sympathetic effects: hypertension, extrasystoles, headache, faintness.
Beta-Adrenergic Blockers
- Reduce IOP; may cause transient burning, discomfort, blurred vision, pain, and photophobia.
- Systemic effects: dizziness, headache, cardiac irregularities, bronchospasm.
Carbonic Anhydrase Inhibitors
- Reduce IOP but are used less frequently due to adverse effects.
- Oral adverse effects include drowsiness, confusion, transient myopia, tinnitus, anorexia, vomiting, diarrhea.
Osmotic Diuretics
- First-line: glycerin; Second: mannitol; Third: isosorbide.
- Used before & after ocular surgery to reduce IOP.
- Possible gastrointestinal issues and fluid or electrolyte imbalances.
Prostaglandin Agonists
- Newest class of drugs for glaucoma; example: latanoprost (Xalatan).
- Reduces IOP and may permanently change eye color to brown.
Erythromycin
- Macrolide antibiotic used to prevent gonorrhea eye infections in newborns and treat chlamydia-induced conjunctivitis.
Trifluridine
- Used for ocular infections caused by herpes simplex virus types 1 & 2.
- Adverse effects: secondary glaucoma, corneal punctate defects, uveitis, stromal edema.
Antifungal Treatments
- Natamycin (Natacyn): anti-fungal used topically for blepharitis, conjunctivitis, and keratitis.
Antibiotic Use with Corticosteroids
- Combining ophthalmic antibiotics with corticosteroids may complicate infection resolution.
Ocular Anti-Inflammatories
- NSAIDs and corticosteroids used prophylactically after surgery to prevent inflammation and scarring.
Ophthalmic Anesthetics
- Used only in-office settings and not for self-administration.
Atropine Sulfate
- Cycloplegic mydriatic used in ophthalmic examinations for dilation.
Diagnostic Dye
- Ophthalmic dye (fluorescein) identifies corneal defects and locates foreign objects; also used for fitting hard contact lenses.
Artificial Tears
- Provide lubrication or moisture for dry or irritated eyes.
Restasis
- Immunosuppressant drug used to treat dry eyes.
Systemic Absorption Reduction
- Apply pressure to the inner canthus for at least 1 minute to minimize systemic absorption of ophthalmic drugs.
