When are steroid eye drops used in patients with inflammatory eye conditions, such as uveitis, conjunctivitis, or keratitis?

When to Use Steroid Eye Drops

Steroid eye drops are indicated for steroid-responsive inflammatory conditions of the anterior segment of the eye, including allergic conjunctivitis, keratitis (excluding herpetic), iritis, cyclitis, and selected infective conjunctivitides when the benefit of reducing inflammation outweighs the risks of steroid use. 1

Primary Indications by Condition

Anterior Uveitis (Iritis/Cyclitis)

• Topical corticosteroids are first-line treatment, starting with prednisolone acetate 1% or dexamethasone at frequent dosing (every 1-2 hours while awake), then tapering based on response 2
• The goal is to reduce use to ≤2 drops daily within 2-3 months to minimize cataract risk (0% cataract incidence at ≤2 drops/day) 2
• If requiring >2 drops daily for >2-3 months, add systemic immunosuppression rather than continuing high-dose topical steroids 2

Allergic Conjunctivitis

• Topical corticosteroids are indicated for steroid-responsive allergic conjunctivitis 1, 3
• For acute exacerbations of vernal/atopic conjunctivitis, topical corticosteroids are usually necessary to control severe symptoms and signs 4
• Patients should be informed about potential complications of corticosteroid therapy, and strategies to minimize corticosteroid use should be employed 4

Keratitis (Non-Herpetic)

• Indicated for superficial punctate keratitis and herpes zoster keratitis 1
• Critical caveat: Herpetic keratitis is an absolute contraindication to corticosteroid use 5
• Topical steroids should not be used without ophthalmologic consultation and should not be used acutely without topical antiviral therapy in suspected viral cases 4

Selected Infective Conjunctivitides

• May be used when the inherent hazard of steroid use is accepted to obtain diminution in edema and inflammation 1
• Clinical data show that ophthalmic formulations combining corticosteroids with broad-spectrum anti-infectives can be effective and well tolerated for short-term treatment (≤2 weeks) 6

Post-Operative Inflammation

• Loteprednol etabonate is specifically indicated for treatment of post-operative inflammation following ocular surgery 3

Corneal Injury

• Indicated for corneal injury from chemical, radiation, or thermal burns, or penetration of foreign bodies 1

Agent Selection

First-Line Agents

• Prednisolone acetate 1% is the gold standard due to superior corneal penetration 7
• Dexamethasone is equally recommended for both acute and chronic anterior uveitis 7

Safer Alternatives for Prolonged Therapy

• Fluorometholone and loteprednol etabonate are recommended for prolonged therapy due to reduced risk of intraocular pressure elevation and cataract formation 7
• Loteprednol etabonate has an improved safety profile with only 1% incidence of clinically significant IOP increases (≥10 mmHg) compared to 6% with prednisolone acetate 1% 3
• Important limitation: Loteprednol is less effective than prednisolone acetate 1% in acute anterior uveitis (72% vs 87% resolution of anterior chamber cells) and should not be used when a more potent corticosteroid is required 3

Critical Safety Monitoring

Mandatory Monitoring

• Baseline intraocular pressure measurement before initiating therapy 4, 7
• Periodic IOP monitoring during treatment 4, 7
• Pupillary dilation to evaluate for cataract formation 4, 7

Duration Limits

• Short-term use (≤3 months) is strongly emphasized to minimize complications 7
• The risk profile changes dramatically with dosing and duration 7

Tapering Strategy

• Topical corticosteroids should be tapered to the minimum effective dose once inflammation is controlled, rather than abrupt discontinuation, to minimize rebound inflammation 7

When NOT to Use Topical Steroids Alone

Posterior Uveitis

• Topical steroids are NOT appropriate for posterior uveitis 8
• Systemic immunomodulatory therapy with agents such as azathioprine, cyclosporine-A, interferon-alpha, or TNF inhibitors is required 8
• Intravitreal glucocorticoid injection can be considered as an adjunct to systemic treatment in unilateral exacerbation 8

Chronic Anterior Uveitis (JIA-Associated)

• Children with uncontrolled chronic anterior uveitis despite topical steroids require systemic steroid-sparing therapy 4
• Indications include: ongoing activity despite topical steroids, worsening activity on topical steroids, recurrent uncontrolled disease with taper to twice daily or less, development of new ocular complications, or intolerance to topical steroids 4

Immune Checkpoint Inhibitor-Related Uveitis

• For grade 2 episcleritis/uveitis: coordinate treatment with ophthalmologist (topical steroids, cycloplegic agents, systemic steroids) 4
• For grade 3-4: consider systemic steroids in addition to topical/periocular steroids 4
• Critical warning: Starting steroids prior to eye exam may worsen infectious conditions (e.g., herpetic keratitis/uveitis) or mask accurate diagnosis 4

Common Pitfalls to Avoid

• Never use steroids in herpetic keratitis without concurrent antiviral therapy 4, 5
• Avoid prolonged high-dose topical steroids (>3 drops/day) which dramatically increases cataract risk 2
• Do not continue topical steroids as monotherapy beyond 2-3 months if requiring >2 drops daily—transition to systemic immunosuppression 7, 2
• Always rule out infectious causes before initiating steroids, particularly in conjunctivitis 6
• Monitor for steroid-induced complications: posterior subcapsular cataract, elevated IOP/glaucoma, delayed corneal wound healing, and exacerbation of infections 5
