Red Eye

Differential Diagnosis

  • Trauma: Emergent ophthalmology referral in cases of moderate/severe pain, decreased visual acuity

    • Corneal abrasion

    • Foreign body

    • Chemical exposure

  • Vision changes: Emergent ophthalmology referral, especially if associated with pain

    • Keratitis

      • Corneal inflammation due to infection (bacteria, HSV, VZV, EBV, CMV), contact lenses, or corneal abrasion

      • Symptoms: Painful diminished vision +/- photophobia, foreign body sensation, mucopurulent discharge

      • Fluorescein/Wood’s lamp: Eyelid edema, hypopyon (leukocytes in anterior chamber), corneal ulcer

    • Iritis

      • Iris infection/inflammation due to perforating wound, corneal ulcer, or certain autoimmune conditions

      • Acute onset (hours) eye pain radiating to forehead/temple, diminished/blurred vision, photophobia

      • Eye watering/redness, ciliary/perilimbal injection, constricted/sluggish pupils

    • Acute angle-closure glaucoma

      • Obstructed aqueous humor outflow resulting in increased intraocular pressure

      • Acute onset severe/throbbing pain, diminished vision, light halos

      • Diffuse eye redness/watering, decreased visual acuity, pupil dilation with decreased reactivity to light, eye pain/firmness with palpation

  • Non-emergent

    • Blepharitis: Inflammatory condition of eyelid margins

    • Conjunctivitis (most common)

      • Allergic: Azelastine 0.05% (H1 receptor antagonist) 1 drop q12h

      • Keratoconjunctivitis (dry eye): Review history (Sjogren risk factors), medications (anticholinergic, antihistamine, OCPs) and consider trial of artificial tears

      • Viral: Symptomatic treatment

      • Bacterial: Erythromycin 0.5%, apply 0.5 inch long ribbon q6h x 7 days

    • Subconjunctival hemorrhage: Benign and resolve spontaneously

    • Episcleritis: Episcleral inflammation often associated with autoimmune disease (e.g. rheumatoid arthritis)

      • Generally self-limited with resolution in 3 weeks

      • Consider topical steroids for severe cases

Red Eye Ophthalmology Referrals

  • Emergent

    • Mechanism: Acute eye trauma

    • Symptoms

      • Moderate to severe pain

      • Acute vision loss: Associated with recent ocular surgery or concern for keratitis, iritis, acute angle closure glaucoma

    • Physical Exam

      • Vesicular rash (herpetic keratitis)

      • Severe mucopurulent discharge (hyperacute bacterial conjunctivitis)

      • Evidence corneal involvement with fluorescein/Wood's lamp

      • Distorted pupil

  • Non-emergent

    • History of recurrent eye infections or episcleritis episodes

    • Exam: Copious purulent discharge not improving with antibiotics

    • Treatment

      • Pain not relieved with topical anesthetic

      • Indication for starting topical steroids (e.g. severe episcleritis)

Vision Abnormalities/Loss

Adult

Acute: Require emergent evaluation by ophthalmology

  • Trauma: Physical and chemical injuries

  • Acute angle closure glaucoma

  • Retinal tear/detachment

  • Retinal vascular occlusion

    • Risk factors: HTN, DM

    • Sudden, painless visual loss

    • Tortuous, dilated retinal veins on fundoscopic exam +/- cotton wool spots, afferent pupillary defect on affected side

  • Optic nerve disease

Chronic

  • Emergent: Temporal (giant cell) arteritis

    • Epidemiology: Most common ages 70 - 79 years in patient with history of polymyalgia rheumatica

    • Presentation: Age > 50 years with new onset unilateral headache/visual disturbances +/- jaw claudication, fever, anemia, elevated ESR and/or CRP

    • Start prednisone 1 mg/kg (maximum 60 mg/day) q24h

    • Refer for color doppler ultrasonography vs. temporal artery biopsy (gold standard)

    • Consider additional screening for thoracic and abdominal aortic aneurysms due to increased risk

  • Age-related cataracts (most common)

    • Age > 40 years

    • Vision loss associated with glare intolerance/halos worse at night or while driving

    • Refer for surgical intervention when affecting activities of daily living

  • Diabetic retinopathy

    • Age > 50 years and more common in Hispanics

    • Fluctuating vision with floaters, light flashes, visual field deficits

    • Tight glycemic control, fenofibrate, panretinal photocoagulation

  • Glaucoma

    • Age > 40 years and more common in African Americans

    • Progressive peripheral and central field visual loss

    • Lower intraocular pressure with medicated eye drops vs. laser trabeculoplasty

  • Macular degeneration

    • Vision loss worse at night with positive Amsler grid test

    • Macular drusen and retinal pigment abnormalities

    • Slow progression with

      • Smoking cessation

      • AREDS2 vitamin supplementation to slow progression: Vitamin C 500 mg, vitamin E 400 IU, 25 mg zinc, 2 mg cupric oxide, 10 mg lutein, 2 mg zeaxanthin (e.g. PreserVision)

    • VEGF injections e.g. bevacizumab (Avastin) for neovascular subtype

Pediatric

Acute: Emergent consultation for trauma, orbital cellulitis, central retinal artery occlusion, and endophthalmitis

    • Red eye

      • Normal IOP: Keratoconjunctivitis (HSV vs. adenovirus)

Chronic

  • Strabismus: Risk factor for visual loss

    • Unequal alignment and may be esotropic (adduction) or exotropic (abduction)

    • High risk for visual loss (see amblyopia)

    • Refer to pediatric ophthalmology with consideration for surgery if conservative treatment fails

  • Amblyopia

    • Reduction in visual acuity and may be strabismic (unequal alignment), refractive (unequal focus), or deprivational (structural abnormalities obscuring incoming image)

    • Treatment options: Patching, optical penalization, atropine eye drops
