Overview

Red eye is defined as a symptom of red eye as the major clinical finding. A detailed history, baseline ophthalmological tests, and accompanying manifestations can narrow down the differential diagnosis. The duration and laterality of symptoms (uni- vs. bilateral) and the intensity of pain are the main criteria allowing the differentiation of non-critical changes that can be cared for by a general practitioner from diseases calling for elective referral to an ophthalmologist and eye emergencies requiring urgent ophthalmic surgery.

Red eye is one of the most common ophthalmologic conditions in the primary care setting. Inflammation of almost any part of the eye, including the lacrimal glands and eyelids, or faulty tear film can lead to red eye. Primary care physicians often effectively manage red eye, although knowing when to refer patients to an ophthalmologist is crucial.

Causes

Life Threatening Causes

Life-threatening causes include conditions that may result in death or permanent disability within 24 hours if left untreated.

• globe ruptures or perforations
• intraocular infections
• Carotid–cavernous sinus fistula

Common Causes

infectious

• Viral conjunctivitis
• bacterial
• Iritis/iridocyclitis

noninfectious

• Acute angle-closure glaucoma
• Disorders of the ocular adnexa(Hordeolum-Eyelid malposition)
• Eyelid malposition
• Intraocular disorders
• Episcleritis
• Photokeratitis
• Corneal erosion/ulceration
• Subconjunctival hemorrhage
• Allergic reactions
• Non-infectious (kerato-)conjunctivitis
• Contact lens
• blunt or penetrating trauma
• foreign bodies

Shown below is an algorithm summarizing the diagnosis of [[red eye]] according the the [...] guidelines.

Age Group		Common Etiology
Neonates*	< 24 hrs	Chemical conjunctivitis
	< 1 week	Neisseria gonorrhea
	1-2 wks	Chlamydia trachomatis
Infants and Toddlers	Without otitis	Haemolphilus. influenzae, Streptococcus pneumoniae
	With otitis	H. influenzae
School Age Children	1-5 years	Herpes simplex virusVaricella-zoster
School Age Children and Adolescents		Viral conjunctivitisAllergic conjunctivtis

Treatment

Shown below is an algorithm summarizing the treatment of [[Red eye ]] according the the [American family physician ] guidelines.

Good hygiene, such as meticulous hand washing, is important in decreasing the spread of acute viral conjunctivitis.

Any ophthalmic antibiotic may be considered for the treatment of acute bacterial conjunctivitis because they have similar cure rates.

Mild allergic conjunctivitis may be treated with an over-the-counter antihistamine/vasoconstrictor agent, or with a more effective second-generation topical histamine H1 receptor antagonist.

Anti-inflammatory agents (e.g., topical cyclosporine [Restasis]), topical corticosteroids, and systemic omega-3 fatty acids are appropriate therapies for moderate dry eye.

Patients with chronic blepharitis who do not respond adequately to eyelid hygiene and topical antibiotics may benefit from an oral tetracycline or doxycycline.
