Urgent Ophthalmology Referral for Suspected Anterior Uveitis
Refer urgently (same-day or next-day) to ophthalmology for evaluation of possible anterior uveitis in a [age]-year-old [male/female] with acute unilateral ocular pain, photophobia, tearing, and conjunctival injection with normal IOP and no corneal defect.
Recommended Referral Wording
"Urgent ophthalmology referral requested for [age]-year-old [male/female] with acute unilateral eye pain, photophobia, tearing, and conjunctival injection concerning for anterior uveitis. Normal IOP measured at [value] mmHg. No corneal defect on fluorescein examination. Patient has history of hypertension, diabetes, and glaucoma. Requires slit-lamp examination and evaluation for intraocular inflammation. Please see within 24 hours."
Key Clinical Reasoning
The constellation of severe photophobia with ocular pain and conjunctival injection represents a red-flag presentation requiring urgent ophthalmology evaluation 1. This symptom complex distinguishes internal eye disease (uveitis, scleritis) from benign conjunctival surface conditions 2.
Why This is Urgent
- Photophobia is the critical distinguishing feature - it signals intraocular inflammation rather than simple conjunctivitis 1
- Anterior uveitis can cause permanent vision loss if untreated due to:
- Posterior synechiae formation
- Secondary glaucoma
- Cystoid macular edema
- Band keratopathy
Essential Information to Include
Your referral should specify:
- Severity of photophobia - this is the most important red flag 1
- IOP measurement - you've documented normal pressure, which helps exclude acute angle-closure glaucoma 3
- Absence of corneal defect - rules out infectious keratitis as primary diagnosis 1
- Unilateral presentation - helps narrow differential
- Comorbidities - diabetes and glaucoma history are relevant for both differential diagnosis and management 4
Common Pitfalls to Avoid
- Don't delay referral because IOP is normal - anterior uveitis typically presents with normal or even low IOP initially 5
- Don't assume conjunctivitis - the presence of significant photophobia distinguishes internal eye disease from surface disease 2
- Don't miss anisocoria - check pupil reactions before referral, as this would escalate urgency 1
Timeframe
This requires same-day or next-day evaluation, not emergent (within hours) but definitely urgent (within 24 hours) 1, 2. The patient needs slit-lamp examination with detailed anterior chamber assessment that cannot be adequately performed in primary care.
