Mild symptoms, blanches with phenylepherine 2.5% drops
- Self limiting, treat with NSAID drops e.g. ketorolac trometamo tds 1-2 weeks
When to refer
- Rarely need steroids so refer urgent only if severe persistent symptoms
Very severe pain, no blanching with phenylepherine drops, often systemic autoimmune disease
Where to refer:
- Refer to eye casualty for high dose systemic steroids
Risk of misdiagnosis and short steroid course comes with high risk of recurrence, therefore best referred to eye casualty.
If previous corneal graft must be referred to eye casualty very urgently to avoid rejection.
