Steroid eye drop risks — key red flags and review points

Structured for Australian optometry practice.

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.

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.
