Background
- Eye pain with an unremarkable external exam and normal slit-lamp findings poses a diagnostic challenge
- Key concern: must rule out sight- and life-threatening conditions that may not show early external signs
- High-risk diagnoses to consider: optic neuritis, temporal arteritis, acute angle closure glaucoma (early), posterior scleritis, ocular ischemic syndrome
Clinical Features
- Normal external eye exam (no injection, no discharge, no corneal findings)
- Patient reports significant eye pain, periorbital pain, or retrobulbar pain
- May have associated symptoms guiding diagnosis (see below)
Differential Diagnosis
Ocular/Orbital
- Optic neuritis — pain with eye movement, decreased visual acuity, afferent pupillary defect
- Posterior scleritis — deep aching pain, may have decreased VA; scleral thickening on B-scan US
- Acute angle closure glaucoma (early) — elevated IOP may be only finding before conjunctival injection develops
- Ocular ischemic syndrome — dull ache, carotid disease, may have low IOP
Referred Pain
- Sinusitis — frontal/maxillary tenderness, nasal congestion, worse with bending
- Temporal arteritis — age >50, scalp tenderness, jaw claudication, elevated ESR/CRP
- Migraine or cluster headache — headache history, associated aura or autonomic symptoms
- Trigeminal neuralgia — lancinating pain in V1 distribution
- Shingles (herpes zoster ophthalmicus) — may precede rash by days (prodromal pain)
Systemic
- Diabetic cranial neuropathy (CN III, IV, or VI)
Evaluation
- Complete eye exam: visual acuity, pupil exam (APD?), IOP, slit-lamp, dilated fundoscopy
- IOP measurement — critical to rule out early angle closure
- ESR and CRP if age >50 or concern for temporal arteritis
- Consider CT/MRI orbits if orbital or retrobulbar process suspected
- MRI brain/orbits with contrast if optic neuritis suspected
Management
- Treat underlying condition
- If no diagnosis after thorough workup: ophthalmology follow-up within 24-48 hours
Disposition
- Urgent ophthalmology referral for decreased visual acuity, elevated IOP, or APD
- Emergent workup for suspected temporal arteritis (ESR/CRP, start empiric steroids pending biopsy)
