Steroid eye drop risks — key red flags and review points
Structured for Australian optometry practice.
Clinical decision support only
OptoGuide™ supports professional judgement and does not diagnose or replace clinician responsibility.
Quick answer
- Topical steroids can worsen herpetic disease, mask microbial keratitis, raise IOP, and delay recognition of corneal or inflammatory complications.
- The main risk is not the label alone, but steroid use in the wrong diagnosis or without adequate follow-up.
- Check the cornea, anterior chamber, IOP, and the original reason the steroid was started.
- Escalate early when steroid use is linked to pain, reduced vision, dendritic staining, infiltrate, or pressure rise.
Common causes
- IOP rise in a steroid responder.
- Masked or worsened microbial keratitis.
- Herpetic epithelial disease becoming more active or less obvious.
- Delayed recognition of persistent inflammation or corneal compromise.
Red flags (must not miss)
- Reduced vision or increasing pain after steroid commencement.
- Dendritic or geographic staining pattern.
- Corneal infiltrate, epithelial defect, or stromal haze.
- Raised IOP or pressure-related symptoms during steroid use.
- Steroid use without a clear working diagnosis or review plan.
Use OptoGuide™ to guide this decision during consult.
What to check
- Original indication, duration, and current symptom trend.
- Visual acuity and IOP.
- Corneal staining pattern and clarity.
- Anterior chamber activity and pupil findings.
- Whether the clinical picture still fits the original diagnosis.
When to refer
- Same day if steroid use is associated with keratitis, herpetic features, or pressure complications.
- Urgent ophthalmology review when symptoms worsen despite steroid treatment.
- Escalate if the diagnosis is uncertain and steroid exposure may be changing the signs.
Initial management
- Reassess the diagnosis rather than assuming persistent symptoms only need more steroid.
- Document acuity, IOP, staining, and chamber findings clearly.
- Use a low threshold for referral when steroid exposure may be obscuring a corneal or pressure-related problem.
Clinical basis
This guidance reflects standard optometric clinical reasoning based on:
- Australian optometry clinical practice patterns
- Australian medicines regulation and PBS prescribing context
- Common ophthalmology referral standards
- Evidence-based clinical training and practice
