Study Notes
Ophthalmic Steroids
-
Prednisolone (1%, 0.125%):
- Common ophthalmic steroid
- Available as acetate and phosphate bases
-
Ocular Applications:
- Anterior uveitis (phosphate base not recommended)
- Ocular surface disease (acetate/phosphate base usable)
- Post-op cataract surgery
- Adenoviral keratitis (used to mask symptoms, not for antiviral treatment)
- Problem: Rebound effect
- Combination: Used in combination with antibiotics (e.g., Tobradex) for sterile ulcers
- Important Distinction: Subepithelial infiltrate vs infectious ulcer (size and inflammation differences)
- Side Effect: Increased intraocular pressure (IOP) is a key concern
- Special Considerations: Not for long-term use due to IOP increase
- Related Formulations: PredForte and Pred-Forte (different uses for specific conditions)
-
Loteprednol (0.5%, 0.2%):
- Little or no effect on IOP (always monitor)
- Lower concentrations for anti-allergic use
-
Ocular Applications:
- Chronic adenoviral keratitis
- Thygeson's keratitis
- Vernal keratoconjunctivitis (type 4 situations)
- Pingueculitis (tear film instability and dry spots)
- Corneal dulling
- Mechanism of Pingueculitis Inflammation: Dryness of pinguecula, affecting tear coverage, causing dry spots.
- Important Distinction (Pterygium vs. Pinguecula): Pterygium invades the cornea
-
Rimexolone 1% ophthalmic suspension:
- Little effect on IOP.
- No longer in market due to lack of effectiveness in post-op cataract surgery
-
Fluorometholone (FML):
- Alcohol and acetate base suspensions (0.1% and 0.25%, and 0.1% ointment)
- Alcohol base has higher bioavailability.
- Ocular Applications: Long-term treatment for chronic conditions mentioned.
- Considerations: Episcleritis (not best for nodular type), unpredictable success, idiopathic (underlying autoimmune disease possible).
-
Difluprednate (Durezol 0.5%):
- Indications: Post-op inflammation/pain, Anterior uveitis (short-term treatment protocols)
- Important Note: Requires tapering treatment plan (starts with QID)
- Side Effects: Increased IOP, corneal edema, pain, photophobia, cataract formation in prolonged use.
- Contraindications: Ocular fungal, viral, or mycobacterial infection (applies to all steroids)
-
Ophthalmic Non-steroidal Anti-inflammatory Agents (NSAIDs):
-
Diclofenac (Voltaren 0.1%):
- Post-op cataract surgery (not primary use).
- Can cause corneal melting, so not for inflammation.
- Potential for chronic use side effects: aspirin derivatives and delays in cell migration/ulceration
- Important Note: corneal melting is a serious concern with chronic NSAID use
-
Ketorolac (Acular 0.5%):
- Primarily to manage pain, not inflammation.
- Ocular Applications: Pain management (corneal refractive surgery, allergic conjunctivitis).
Key Considerations for Steroid Use
- Careful Monitoring: Close monitoring of IOP is crucial with any steroid.
- Purpose: Steroids are strong meds that help reduce inflammation but may have side effects - using the proper dosage and frequency is important.
- Uveitis Treatment: Strong uveitis requires aggressive, high-frequency early treatment with tapering strategies.
- Non-Steroid Use: NSAIDs are often supplemental pain relief measures with limited inflammatory benefits and potential issues
