Pre-Triage System Red Need to be seen within a few hrs, further triaging. Amber Need to be seen within 72 hrs, diverted to UCC slots. Green No need for urgent assessment, referred to GP, optometrist or to OPD (via GP).
Red – Very Urgent Penetrating eye injury Acute post-op endophthalmitis Severe chemical injury Orbital cellulitis GCA with visual symptoms Sudden loss of vision <6hrs
Red - Urgent Painful red eye with visual loss Retinal detachment with good VA Corneal ulcer, esp. with CL wear Blunt trauma with hyphaema & ↑ IOP Corneal graft rejection Painful diplopia
Amber Flashes & floaters, no loss of vision Red eye without pain or visual loss Retinal vein occlusions (OPD 4-6/52) Diabetic retinopathy with vitreous haemorrhage Wet AMD (preferably refer to Fast Track Macular Clinic)
Green – GP / Optometrist Mx Bacterial & viral conjunctivitis Allergic conjunctivitis Blepharitis Dry eyes Lid lumps and bumps
Green – OPD Referral Cataract Chronic / gradual visual loss (months) Open angle glaucoma, ocular hypertension Watery eyes Ectropion, entropion Lid lumps & bumps Non-acute diplopia
Trauma Burns Abrasions & lacerations Foreign bodies Blunt trauma Acid, alkali, thermal, arc eye Abrasions & lacerations Lid, corneal and conjunctival, Penetrating Eye Injuries Foreign bodies Corneal, conjunctival, sub-tarsal, intra-ocular Blunt trauma Sub-conjunctival haemorrhage, hyphaema, choroidal rupture Orbital Blowout Fracture, Traumatic Optic Neuropathy
Chemical Injury Emergency Alkali or Acid pH check Immediate irrigation May result in limbal stem cell failure
Corneal Abrasion History provides diagnosis & indication of severity Mostly doesn’t require A & E Oc. Chloramphenicol qid 5/7
Foreign Bodies Can be removed if confident g. Chlor qid 5/7 Refer (PEARS?) if unable to remove or rust rings Always check for subtarsal FB as well
Sub-conjunctival Haemorrhage Spontaneous vs traumatic Self limiting No treatment No referral required
Blow Out Fracture Assess for globe damage, Traumatic Optic Neuropathy Orbital surgery only if tissue entrapment Normally performed within 4/52
Cornea Dry eye Recurrent erosion syndrome Ulcers Shingles CL related Acanthamoeba Dendritic Shingles
Dry Eyes Lubricants Look for blepharitis Refer OPD only if unable to improve symptoms
Recurrent Corneal Erosion H/O Index injury Typically pain on waking / opening eyes Oc. Simple / Lacrilube nocte 3/12 Refer OPD if no improvement
Bacterial Keratitis Esp in CL wearers Excess wear, poor hygiene Urgent referral Differentiate from marginal keratitis
Dendritic Ulcer Typically HSV 1, as with cold sores Self limiting Treat with topical Acyclovir / Valgancyclovir 5x/d, 7/7 UCC referral
Herpes Zoster Ophthalmicus Oral antiviral Rx if started within 72hrs onset of rash Not always eye involvement Hutchinson’s sign 70% chance eye involvement Most eye involvement doesn’t require specialist Rx
Conjunctiva Conjunctivitis Episcleritis Scleritis Bacterial, viral, allergic Episcleritis Scleritis
Bacterial Conjunctivitis Purulent / mucopurulent discharge Self limiting OTC g. Chlor qid 1/52 No referral required
Viral Conjunctivitis Watery discharge Follicular reaction Self limiting No referral required unless corneal involvement
Allergic Conjunctivitis Identification and avoidance of trigger allergen Topical Sodium cromoglycate Oral anti-histamines No referral required unless persistent problem
Episcleritis Self limiting Mild – Moderate discomfort Oral NSAIDs, eg ibuprofen No referral required unless persistence Steroid dependency
Scleritis Severe dull boring pain Brawny red appearance Strong association with auto-immune and connective tissue disease Urgent referral Needs extensive management
Lids Blepharitis Chalazion, stye Ectropion, entropion Anterior, posterior Chalazion, stye Ectropion, entropion Pre-septal cellulitis
Anterior & Posterior Blepharitis Lid hygiene Hot compresses Treat associated dry eye No referral required
Chalazion Hot compresses I&C if refractory Prescribe oral Abx if infected No referral to A & E
Senile Ectropion & Entropion Ensure lubrication of ocular surface No acute management in A & E Refer routinely
Pre-Septal Cellulitis Need to differentiate with orbital cellulitis Pt not systemically unwell No orbital signs Needs oral Abx (GP) Refer if in doubt
Orbital Cellulitis Potentially sight / life threatening condition Pt systemically unwell, pyrexial Orbital signs Emergency referral Need admission and IV ABx
Neuro-ophthalmology IIIrd, IVth, VIth nerve palsies Optic neuritis Papilloedema Giant cell arteritis
3rd, 4th, 6th Palsy Majority will be microvascular in elderly diabetic hypertensive population Consider duration Beware of painful nerve palsy esp 3rd PCA aneurysm Beware of assoc headache esp 6th GCA
Disc Swelling Physiological Hypermetropes Optic cup SVP Vessel changes Exudates Haemorrhages Hyperaemia Retinal folds VISUAL SYMPTOMS?
Optic Neuritis Mostly due to demyelination Unilateral vs bilateral Child vs adult 2/52 ↓, 2/52 ↔, 2/52 ↑ Reduced vision, colour vision, RAPD Uhtoff’s phenomenon Pain esp ocular movement Haemorrhages Hyperaemia Venous distension Swelling Or no physical signs
Papilloedema Due to raised ICP Bilateral Reduced vision Obscurations Blind spot enlargement Haems Hyperaemia Tortuous congested vessels Exudates Cup obliteration Retinal folds
Giant Cell Arteritis Temporal headache and tenderness Blurred vision Jaw claudication Polymyalgia Associated with RAOs Emergency referral to Eye Cas ONLY if visual symptoms eg. Amaurosis Otherwise refer urgently to Rheumatology / Physicians
Glaucoma Open vs Closed angle 1̊ vs 2̊ Neovascular What IOP is urgent? <30mmHg refer to outpatients >30mmHg D/W on call team
Acute Angle Closure Glaucoma Typically presents midday onwards Fixed, semi-dilated pupil High pressure, corneal oedema Closed angle – may need to examine fellow eye Emergency referral Needs medical treatment then laser iridotomy More extensive surgery may be necessary
Vitreo & Medical Retina Posterior Vitreous Detachment Vitreous haemorrhage Retinal tears and holes Retinal detachment Wet AMD Vascular occlusions Proliferative diabetic retinopathy
Posterior Vitreous Detachment Only 30-50% PVD symptomatic Symptomatic PVD refer to UCC, depending on duration Most are not associated with retinal detachment
Vitreous Haemorrhage Check for systemic associations eg. DM, HT, Sickle Examine fellow eye If present, UCC referral (duration dependent) In absence of systemic disease, PVD with VH has 70% incidence of retinal tear Urgent referral to Eye Cas
Retinal Detachment Is the macula on or off? VA Clinical exam If on, emergency referral If off, Eye Cas, UCC or clinic depending on duration Check for symptoms of chronicity Not all detachments are an emergency!
Wet Macular Degeneration Sudden onset reduction of vision, distortion H/O dry AMD Optician can diagnose Fast track macular service
Venous Occlusions No emergency treatment available Refer via fast track system Need long term treatment
Arterial Occlusions Irreversible retinal damage from 4hrs of onset Immediate emergency treatment up to 8hrs from onset Aspirin ocular massage rebreathing into bag Beyond this time no heroic measures Check for GCA symptoms Stroke/TIA pathway
Proliferative Retinopathy Most commonly diabetics Also Sickle, prior RVOs and rarely RAOs Refer to UCC unless also VH
