Red eye
The most common presenting symptom of
patients presenting with ophthalmic
problems /emergencies
![Page 6: Common eye conditions & their management in Primary … · Common eye conditions & their management in Primary care ... • Internal Hordeolum • Stye ... PowerPoint Presentation](https://reader031.vdocuments.us/reader031/viewer/2022013117/5b81bf1a7f8b9ae87c8cfcfa/html5/thumbnails/6.jpg)
Red Eye
Patients presenting with a red eye usually present in
one of the following ways:
The red eye can be painful or is painless
Or
It is accompanied with or without discharge
Or
Accompanied by blurring of vision or not
![Page 7: Common eye conditions & their management in Primary … · Common eye conditions & their management in Primary care ... • Internal Hordeolum • Stye ... PowerPoint Presentation](https://reader031.vdocuments.us/reader031/viewer/2022013117/5b81bf1a7f8b9ae87c8cfcfa/html5/thumbnails/7.jpg)
What causes a red eye ?
• Red eye is caused by either :
• Dilatation of
– Conjunctival blood vessels e.g conjunctivitis
– Episcleral blood vessels e.g episcleritis
– Scleral blood vessels e.g scleritis
• Or
– Accumulation of blood in the subconjunctival space i.e
Subconjunctival haemorrhage
![Page 8: Common eye conditions & their management in Primary … · Common eye conditions & their management in Primary care ... • Internal Hordeolum • Stye ... PowerPoint Presentation](https://reader031.vdocuments.us/reader031/viewer/2022013117/5b81bf1a7f8b9ae87c8cfcfa/html5/thumbnails/8.jpg)
What causes a discharge in a red
eye?
• Discharge in a red eye is caused by
either
• Exudation/transudation form conjunctival
vessels
• Due to over production of tears
• Due to blockage of tear passages.
![Page 9: Common eye conditions & their management in Primary … · Common eye conditions & their management in Primary care ... • Internal Hordeolum • Stye ... PowerPoint Presentation](https://reader031.vdocuments.us/reader031/viewer/2022013117/5b81bf1a7f8b9ae87c8cfcfa/html5/thumbnails/9.jpg)
What causes pain in a red eye ?
• Pain is caused by irritation of the:
– Conjunctival nerves e.g dull ache in conjunctivitis
– Corneal nerves: pain in corneal ulcer
– Ciliary nerves: pain in scleritis, uveitis and angle closure glaucoma
It is important to remember that the orbit is surrounded by air sinuses and inflammation of these is also an
important cause of pain around the eyes

Causes of a painless red eye
• Sub conjunctival haemorrhage
and
• Episcleritis are the two important causes of a painless red eye.
• The other causes of a localised redness are:
• Pterygium and
• Pigencula
• Please note that all of the above do not usually have accompanying discharge or epiphora.

In summary
• When confronted with a patient with a red eye
• Decide weather it is painless or painful
• Identify the structure of the eye which is involved
• Try to ascertain if the cause is
infective/traumatic/allergic
• Always rule out trauma
• Check intraocular pressure
• And if in Doubt ask for advice.

Sudden loss of vision
Management:
Urgent referral to HES
![Page 35: Common eye conditions & their management in Primary … · Common eye conditions & their management in Primary care ... • Internal Hordeolum • Stye ... PowerPoint Presentation](https://reader031.vdocuments.us/reader031/viewer/2022013117/5b81bf1a7f8b9ae87c8cfcfa/html5/thumbnails/35.jpg)
Sudden loss of vision can be
• total
• partial,
• transient or
• permanent
• involving either one or both eyes.
![Page 36: Common eye conditions & their management in Primary … · Common eye conditions & their management in Primary care ... • Internal Hordeolum • Stye ... PowerPoint Presentation](https://reader031.vdocuments.us/reader031/viewer/2022013117/5b81bf1a7f8b9ae87c8cfcfa/html5/thumbnails/36.jpg)
Common causes of sudden loss
of vision are
Transient ischemic attacks
• Cause sudden complete loss of vision in one eye, typically regaining full visual function within a few minutes to several hours.
• Are often associated with other neurological symptoms such as weakness in a limb or "pins-and-needles" sensations. If recurrent should be investigated as they may be early warning signs of an impending neurological disaster
• A stroke involving your visual areas in the brain can cause permanent defects in the visual fields of both eyes, and the only treatment is prevention!
• Management: Assessment of the causes… Doppler etc
![Page 37: Common eye conditions & their management in Primary … · Common eye conditions & their management in Primary care ... • Internal Hordeolum • Stye ... PowerPoint Presentation](https://reader031.vdocuments.us/reader031/viewer/2022013117/5b81bf1a7f8b9ae87c8cfcfa/html5/thumbnails/37.jpg)
Retinal detachment
A condition where the light-sensitive part of your inner eye detaches from its supporting structures and tends to fold up inside the eye, causing loss of vision.
Typical clinical picture starts with one or more of the
following symptoms:
– Lightning flashes visible in your peripheral field, or
– A new "floater" or a shower of floaters appearing suddenly, and
– finally a sudden black "curtain" descending in your visual field.
– Management: Urgent to HES

Vascular occlusion
Sudden complete visual loss can also be caused
by thrombosis or occlusion of the retinal blood
vessels, usually in one eye only, due to a blood-
clot or occlusion by pieces of atherosclerotic
plaques from the heart valves or large vessels of
the neck. People suffering with diabetes, high
blood pressure or elevated cholesterol are
particularly prone to these conditions.

Vitreous haemorrhage
• Diabetics with diabetic eye disease (diabetic
retinopathy) can also develop spontaneous
hemorrhaging inside the eye due to rupturing
of abnormal blood vessels, with resultant
sudden blindness. The blood will sometimes
absorb on its own, but can be removed by
microsurgical means to restore vision.
• These patients usually have such advanced
underlying retinal disease
![Page 45: Common eye conditions & their management in Primary … · Common eye conditions & their management in Primary care ... • Internal Hordeolum • Stye ... PowerPoint Presentation](https://reader031.vdocuments.us/reader031/viewer/2022013117/5b81bf1a7f8b9ae87c8cfcfa/html5/thumbnails/45.jpg)
Age related Macular degeneration
• Hemorrhaging under the retina due to age-related macular
degeneration (ARMD), is another common cause of sudden
blindness.
• This is a condition where the central visual area of the retina
becomes atrophic, with abnormal deposits, called "drusen". This
could lead to ingrowth of abnormal blood vessels that may rupture
and cause a so-called "disciform" hemorrhage.
• Macular degeneration, however, is usually a much more insidious
and slowly progressing disease, and not all age-related macular
degenerations have sudden visual loss, but rather a more gradual
deterioration over a few years.

Case 1
Problem
• 67 y/o male with hypertension, and poor compliance presents complaining of sudden decreased vision in Right eye.

Approach
• Age and medical background support an underlying vascular event having taken place. A careful fundus exam is required

Case 2
A 21 y/o female states that over the last 2 days her vision has decreased in her right eye to counting fingers vision. Denies any pain or trauma.

Approach
• In this age group an otherwise healthy patient should be suspected of having an optic nerve lesion. Checking for a relative afferent
pupillary defect would be a prudent test.

Case 3
• A 55 y/o female 12 h after coronary artery bypass surgery complains of being unable to see from her left eye.
• There is no pain and externally the eye appears normal.

Approach
• Post-op loss of vision tends to be vascular in nature. Either an embolic phenomena (very likely in this case) or compression of the eye during prolonged
anaesthesia, precipitates a vascular compromise.

Case 4
• A 40 y/o male states he lost vision in his right eye after seeing flashing lights and "spider webs." He is a -10.00 myope.

Approach
• High myopia with associated flashes and floaters should make one think of a retinal detachment proven otherwise. A dilated fundus exam followed by an
appropriate referral is advised.

Case 5
• A 77 y/o female is sent to you from geriatrics. She was initially being worked up for lethargy and weight loss. Complained of vision coming and going for several days and now states she cannot see anything at all out of both eyes.

Approach
• Elderly patients with sudden loss of vision associated with constitutional symptoms raises the specter of Giant Cell Arteritis. After careful history and examination a CRP/ ESR should be ordered.
• This will not reverse the visual loss but will substantially
reduce the risk of cardiac or CNS events.

Case 6
• A 38 y/o male with longstanding insulin-dependent diabetes presents with sudden loss of vision in his left eye. Has had only moderate control of his diabetes over the last several years stating he takes his insulin when he feels like it.

Approach
History of poorly controlled diabetes makes one suspicious of neovascularization of the retina. Vitreous hemorrhage is at the top of
the list.

In summary
• All cases of sudden loss of vision should be taken very seriously as they usually have an underlying cause
• Look for causes form anterior to posterior
Cornea AC Lens Vitreous retina optic nerve brain
Correlate with the underlying general health
Formulate a provisional diagnosis
If in doubt refer urgent/semi-urgent
