Can a Patient with Glaucoma Use Prednisone?

Prednisone and other systemic corticosteroids can be used cautiously in patients with glaucoma, but they carry significant risk of elevating intraocular pressure (IOP) and worsening glaucoma, particularly with chronic use—topical corticosteroid eye drops pose the greatest danger and should be avoided or used only short-term with intensive monitoring. 1, 2

Critical Safety Considerations

Risk Profile by Route of Administration

• Topical corticosteroid eye drops represent the highest risk for IOP elevation and glaucoma progression, causing gradual, insidious, and irreversible vision loss in patients with open-angle glaucoma 2
• The FDA label for prednisone explicitly warns that corticosteroid use may produce glaucoma with possible damage to the optic nerves 1
• Systemic corticosteroids (oral prednisone) carry lower but still significant risk compared to topical formulations 3, 4

Patient-Specific Risk Factors

• Approximately 46-92% of patients with primary open-angle glaucoma (POAG) are corticosteroid responders, compared to only 18-36% of the general population 4
• Patients over 40 years of age have increased vulnerability to corticosteroid-induced glaucoma 4
• Additional risk factors include: family history of POAG, diabetes mellitus, and high myopia 4

Clinical Decision Algorithm

When Systemic Prednisone May Be Acceptable

• Short-term bridging therapy (≤3 months) for specific inflammatory conditions may be considered with intensive IOP monitoring 5
• The risk-benefit ratio must strongly favor treatment, such as in vision-threatening uveitis or systemic inflammatory conditions 5
• One case report demonstrated successful use of prednisone 60 mg daily with taper for uveal effusion syndrome in a patient with angle closure glaucoma, though this required concurrent aggressive glaucoma management 6

Mandatory Monitoring Protocol

• Baseline IOP measurement before initiating corticosteroids is essential 3
• IOP follow-ups must occur during and after corticosteroid use, with frequency determined by glaucoma severity and corticosteroid dose 3
• Patient and practitioner education about glaucoma risk is critical for prevention 3, 4

When to Avoid Corticosteroids

• Chronic corticosteroid use should be avoided in glaucoma patients whenever possible 2
• If topical corticosteroid eye drops are absolutely necessary, they should be limited to ≤3 months with the goal of discontinuation due to risk of glaucoma and cataracts 5
• Consider alternative immunosuppressive agents (methotrexate, biologics) for conditions requiring long-term anti-inflammatory therapy 5

Management of Corticosteroid-Induced IOP Elevation

• If IOP elevation occurs, initiate or intensify IOP-lowering medications immediately 3
• Consider switching to corticosteroid formulations with lower ocular penetration if topical therapy is unavoidable 5
• Loteprednol etabonate and fluorometholone phosphate have more favorable safety profiles for minimizing IOP elevation 5

Common Pitfalls to Avoid

• Do not dismiss the package insert warning about glaucoma for systemic corticosteroids—while anticholinergic pupil dilation warnings can often be ignored, corticosteroid warnings are clinically significant 2
• Do not assume all glaucoma patients respond equally to corticosteroids; individual steroid responsiveness varies significantly 4
• Do not use topical corticosteroid eye drops chronically without ophthalmology co-management 5

Special Circumstances

• In juvenile idiopathic arthritis-associated uveitis, topical glucocorticoids (prednisolone acetate 1%) should be used short-term with systemic therapy added if control requires >1-2 drops/day for 2-3 months 5
• Post-trabeculectomy patients may actually benefit from topical prednisolone 1%, which showed lower IOP and better outcomes at 5 years compared to no steroid treatment 7—this represents a unique exception where corticosteroids improve glaucoma surgical outcomes
