Overview• Acute eye problems in community setting

– Examination

– Differential diagnosis

– Management guidance

• Guidance / referral pathways for a few common

eye conditions– Watery eye / dry eye / Blepharitis

– Flashes and floaters

– AMD

– Diabetic retinopathy

Acute eye problems in community setting

The Red Eye

• Common causes

– Lids

• Blepharitis

– Ocular surface

• Tear film

• Conjunctiva

• Cornea

– Intraocular causes

• Anterior uveitis (iritis)

• Acute angle closure glaucoma


The Red Eye

• History

– Lids

• Sore, crusty eye lid margins/eyelashes. Long history (Blepharitis)

– Ocular surface

• Tear film – grittiness (Dry eye)

• Conjunctiva – grittiness, watery / sticky disch, contact history (Conjunctivitis)

• Cornea – Pain ++. h/o FB, Contact lens (Ulcer / Abrasion)


• Anterior uveitis (iritis) – pain++, tenderness, photophobia

• Acute angle closure glaucoma – pain++, reduced vision


The Red Eye

• Examination

– Lids

• Crusty eye lid margins/eyelashes. Periocular skin

– Ocular surface

• Tear film – Tear meniscus……fluorescein dye

• Conjunctiva – generalised congestion, tarsal conj., cornea is clear

• Cornea – Corneal haze, fluorescein dye


• Anterior uveitis (iritis) – circumcorneal congestion, cells, flare, hypopyon

• Acute angle closure glaucoma – CCC, corneal clouding, shallow AC, fixed dilated

pupil

• Acute angle closure glaucoma – CCC, corneal clouding, shallow AC, fixed

dilated pupil


Management

• Treatable in primary care

– Blepharitis - lid hygiene, topical lubricants

– Dry Eye - Topical lubricants (drops / gel + ointment at night)

– Conjunctivitis (Chlamydia – GUM)

• Refer to secondary care

– Corneal ulcer (?abrasion)

– Corneal problems in CL wearers

– Anterior uveitis (early treatment – quicker response…….topical steroids

……..recurrent AAU)

– Acute angle closure (ophthalmic emergency)


– Examination






– AMD


Watery Eye

Watery Eye

• Excessive tear production

– Any irritation to ocular surface

(ingrowing eyelash, blepharitis, “cold wind”,

allergy)

– “Dry Eye”

• Problems with tear outflow

Watery Eye• Excessive tear production

– Any irritation to ocular surface

(ingrowing eyelash, FB, “cold wind”, allergy)

– “Dry Eye”

• Problems with tear outflow

– Eyelid malposition (punctal eversion / stenosis,

ectropion)

– Blocked tear duct

Watery Eye

• When to refer

– Persistent, constant watering eyes

– Punctal stenosis, trichiasis – minor op

– Punctal / lid malposition – oculoplastic surgery

– Suspected blocked tear duct – oculoplastic

surgery


– Dry eye , blepharitis

Watery Eye

• When to refer




– Suspected blocked tear duct – oculoplastic

surgery



Dry eyeMild to moderate • topical lubricants• Drops / Gel / Ointment• Preservative-free dropsModerate to severe• Punctal occlusion• Refer to eye clinic

BlepharitisMild to moderate • Lid hygeine• Topical lubricants

Moderate to severe• Oral doxycycline• Refer to eye clinic

Watery Eye

• When to refer




– Suspected blocked tear duct – oculoplastic surgery



• Managing patient expectations


– Examination






– AMD


Flashes and Floaters

Posterior Vitreous Detachment

(PVD)

PVD Retinal D

Flashes and Floaters• Urgent referral to eye clinic

– Sudden onset, multiple floaters

– Recent onset, multiple flashes of light

– “Curtain” / visual field defect

• Non-urgent / No referral to eye clinic

– Long duration of floaters

– Occasional flash of light


– Examination






– AMD


AMD• Dry AMD

– Gradual decline in vision

– Central vision impaired

– Long standing / slowly worsening distortion in

central vision

– Management

• Dietary supplements

• Supportive care (LVA, NGOs, CVI)

• Wet AMD

Wet (neovascular) AMD• Vision loss is more rapid

• Warning symptoms

– Recent onset distortion of central vision

– Recent onset blurred central vision

• Referral pathway

– Direct referral from Optom to fast track macula clinic (Fax

to WEI)

• Management

– Intravitreal injections

– Dietary supplements

– Supportive care (LVA, NGOs, CVI)


– Examination






– AMD


Diabetic Retinopathy• All patients with DM – screened by DESP

• Patients with “referable retinopathy” are seen in hospital eye clinics

• Asymptomatic patients picked up DR at routine eye test:

– Are they being screened by DESP

– Are they already under care of HES? (WEI / WMH)

– Please write to the concerned Consultant

• Management

– Laser treatment – WMH / WEI

– Intravitreal injections for DMO (WEI only)

• How can primary care team help?

– Control of systemic risk factors – sugar, BP, cholesteral

– Fenofibrate?

In summary• Red, painful eye

• Differential diagnosis

• Which of these patients can be treated within primary

care and identifying those that need urgent referral?

• Management and referral pathways for

some common eye conditions

• Watery eye

• Flashes and floaters

• AMD

• DR
