What is the best treatment approach for an adult patient with dry eyes and a history of ocular surface inflammation or chronic use of steroid eye drops?

Treatment of Dry Eyes in Patients with Ocular Surface Inflammation or Chronic Steroid Use

For patients with dry eyes and a history of ocular surface inflammation or chronic steroid use, initiate preservative-free artificial tears at least 4 times daily combined with lid hygiene, then add short-term topical corticosteroids (maximum 2-4 weeks) only if inflammation persists and the patient has no glaucoma history, followed by transition to cyclosporine 0.05% for long-term anti-inflammatory control. 1, 2

Critical Initial Assessment

Before initiating any anti-inflammatory therapy, you must:

• Rule out glaucoma or ocular hypertension history – topical corticosteroids are absolutely contraindicated in these patients due to IOP elevation risk 2, 3
• Assess severity of ocular surface inflammation through conjunctival hyperemia grading and corneal/conjunctival staining 1, 4
• Identify contributing factors: blepharitis, meibomian gland dysfunction, incomplete blinking, environmental triggers, or systemic medications 1

Staged Treatment Algorithm

Step 1: Foundation Therapy (All Patients)

• Preservative-free artificial tears containing methylcellulose or hyaluronate at least 4 times daily, increasing up to hourly based on symptoms 2, 1
• Lipid-containing tear supplements if meibomian gland dysfunction is present 1
• Lid hygiene: warm compresses 5-10 minutes twice daily followed by gentle massage and eyelid margin cleansing 5, 1
• Environmental modifications: increase humidity, avoid air drafts, lower computer screens below eye level, use side shields on spectacles 1
• Eliminate exacerbating medications when possible (antihistamines, diuretics) and avoid cigarette smoke exposure 1, 6

Step 2: Short-Term Anti-Inflammatory Therapy (If Step 1 Inadequate After 2-4 Weeks)

For patients WITHOUT glaucoma/ocular hypertension history:

• Topical corticosteroids for maximum 2-4 weeks only 1, 2
  • Loteprednol etabonate 0.5% is preferred due to lower IOP elevation risk (1% vs 6% with prednisolone) 3
  • Hydrocortisone 0.335% is an alternative with excellent safety profile and no IOP changes in clinical trials 4
  • Monitor IOP at baseline and every 1-2 weeks during treatment 2
  • Screen for secondary infections (bacterial, fungal, viral) during use 2

Critical pitfall: Never extend corticosteroid use beyond 4 weeks due to risks of infection, IOP elevation, and cataract formation 2, 7

Step 3: Transition to Long-Term Immunomodulation

• Cyclosporine 0.05% twice daily should be initiated before or during steroid taper for sustained anti-inflammatory control 1, 2

  • Success rates of 67-74% for long-term symptom control 2
  • Pre-treating with corticosteroids for 2 weeks before cyclosporine initiation reduces initial stinging and provides faster symptom relief 2
  • Expect 6-12 weeks for full therapeutic effect 1, 8

• Lifitegrast (LFA-1 antagonist) is an alternative topical immunomodulator 1

Step 4: Advanced Therapies for Refractory Cases

If symptoms persist despite optimized Step 1-3 therapy:

• Punctal occlusion (temporary collagen plugs first, then silicone or surgical cautery) 1
• Autologous serum eye drops for severe cases, particularly with Sjögren's syndrome 2, 9
• Oral tetracyclines (doxycycline) or macrolides for meibomian gland dysfunction with anti-inflammatory effects 1
• Moisture chamber goggles for overnight or daytime use 1

Special Considerations for Chronic Steroid Users

If the patient has been on chronic topical steroids:

• Immediately taper and discontinue if used beyond 4 weeks 2, 7
• Check IOP urgently – chronic steroid use causes glaucoma in susceptible individuals 2, 3
• Transition to cyclosporine or lifitegrast for maintenance anti-inflammatory therapy 1, 2
• Screen for steroid-induced complications: cataract formation, secondary infections, corneal thinning 2, 7

The key error in chronic steroid users is failing to recognize that corticosteroids mask inflammation temporarily but do not address underlying pathophysiology – you must transition to disease-modifying agents like cyclosporine 8, 10

When to Refer to Ophthalmology

Immediate referral required for:

• Lack of response after 2-4 weeks of optimized treatment 2, 6
• Any vision loss, corneal infiltration, or ulceration 2, 6
• Patients requiring steroids beyond 4 weeks need specialist management 2
• History of glaucoma/ocular hypertension requiring anti-inflammatory therapy 2
• Severe dry eye with corneal complications: keratinization, scarring, neovascularization, ulceration 1

Common Treatment Failures to Avoid

• Using preserved artificial tears more than 4 times daily causes ocular surface toxicity – switch to preservative-free formulations 2, 6
• Failing to treat underlying blepharitis or meibomian gland dysfunction will cause treatment failure regardless of tear supplementation 2, 1
• Inadequate patient education about chronic disease nature leads to poor compliance – set realistic expectations 1
• Monotherapy with artificial tears alone when inflammation is present – inflammation must be addressed with anti-inflammatory agents 9, 10
