This list is intended to be guidance about which conditions require emergency or urgent referral.
Emergency referral (within 24 hours), symptoms or signs suggesting:
- Acute glaucoma
- Acute dacryocystitis in children, or in adults if severe
- Cellulitis (preseptal or orbital)
- Corneal foreign body penetrated into stroma, or with presence of a rust ring (unless optometrist is specifically trained in rust ring removal)
- CRAO
- Endophthalmitis
- Facial palsy, if new or with loss of corneal sensation
- Herpes zoster ophthalmicus with acute skin lesions (emergency referral to GP for systemic anti-viral treatment with urgent referral to ophthalmology if deeper cornea involved)
- Hyphaema
- Hypopyon
- IOP>/40mmHg (independent of cause)
- Microbial keratitis
- Orbital cellulitis
- Papilloedema
- Penetrating injuries
- Pre-retinal haemorrhage, although a pre-retinal haemorrhage in a diabetic patient with known proliferative retinopathy who is already being actively treated in the HES would not need an emergency referral
- Retinal detachment unless this is long-standing and asymptomatic
- Scleritis
- Sudden severe ocular pain
- Suspected temporal arteritis
- Symptomatic retinal breaks and tears
- Third nerve palsy with pain
- Trauma (blunt or chemical), if severe
- Unexplained sudden loss of vision
- Uveitis
- Vitreous detachment symptoms with pigment in the vitreous
- Viral conjunctivitis if severe (e.g. presence of pseudomembrane)
Urgent referral (within one week):
- Acute dacryocystitis, if mild
- Acute dacroadenitis
- Atopic keratoconjunctivitis with corneal epithelial macro-erosion or plaque
- Chlamydial conjunctivitis (refer to GP)
- CMV and candida retinitis
- Commotio retinae
- Corneal hydrops if vascularisation present
- CRVO with elevated IOP (40mmHg refer as emergency)
- Herpes zoster ophthalmicus with deeper corneal involvement – urgent referral to ophthalmology, but refer to GP as an emergency for systemic anti-viral treatment
- IOP>35 mm Hg (and <40mmHg) with visual field loss
- Keratoconjunctivitis sicca if Stevens-Johnson syndrome or ocular cicatricial pemphigoid are suspected
- Retinal detachment if not an emergency, see above
- Retrobulbar/optic neuritis
- Ocular rosacea with severe keratitis
- Rubeosis
- Squamous cell carcinoma
- Steroid induced glaucoma
- Sudden onset diplopia
- Unilateral blepharitis, if carcinoma suspected
- Vernal keratoconjunctivitis with active limbal or corneal involvement
- 'Wet’ macular degeneration/choroidal neovascular membrane, according to local fast-track protocol.
