Overview

Conjunctivitis is the most common eye infection in which inflammation causes dilation of conjunctival blood vessels giving the eye a reddish aspect. The most common cause of conjunctivitis is infection of which viral infections are the commonest cause, followed by bacterial. The non-infection forms are allergic, mechanical, toxic and neoplastic. Among noninfectious conjunctivitis, the allergic form is more common. Infectious conjunctivitis can be presented with many similar symptoms among independently of the cause, such as: red eye, foreign body sensation, itching, light sensitivity, burning. Watery discharge is common in viral conjunctivitis while mucopurulent discharge is more suggestive of bacterial cause. Regarding the onset and severity of clinical symptoms, conjunctivitis is classified as acute, chronic, and recurrent. Most cases of infectious conjunctivitis are considered as acute conjunctivitis. Allergic conjunctivitis can be chronic while it can be present with acute exacerbations related to seasonal factors or contact lens use. It is important to differentiate conjunctivitis from other sight-threatening eye diseases that have similar clinical presentation.

Causes

Life Threatening Causes

Most cases of conjunctivitis are relatively mild and will not cause eye damage of any sort. However, if it left untreated it can lead to sight-treathening complications including:[1]

Viral conjunctivitis

Bacterial conjunctivitis

Diagnosis

Some initial diagnosis should be excluded for which physicians should manage patients by a systematic approach.[5]

Differential Diagnosis

Differential diagnosis Manifestation Examination findings
Blepharitis Burning and foreign-body sensation, symptoms worse with prolonged reading or watching[6] Bilateral redness
Uveitis Photophobia, pain, blurred vision[7][7][7][7][7][7] Decreased vision, poorly reacting pupils, constant eye pain radiating to temple and brow, red-eye
Angle closure glaucoma Headache, nausea, vomiting, ocular pain, decreased vision, light sensitivity[8][8][8][8][8] Firm eye on palpation, ocular redness, steamy cornea
Endophthalmitis[9][9][9] Severe pain, photophobia[9][9][9][9][9][9] Red eye, pus in the anterior chamber, history of eye surgery or ocular trauma
Scleritis Decreased vision, moderate to severe pain[10] Redness, bluish sclera
Subconjunctival hemorrhage Foreign-body sensation and tearing or be asymptomatic[11][11][11][11] Blood under the conjunctival membrane
Corneal abrasion Red-eye, pain, foreign-body sensation and tearing[1] If caused by a foreign-body, it can be found on biomicroscopic exam

Treatment

Medical therapy for conjunctivitis[5]
Category Epidemiology Type of discharge Cause Treatment
Viral conjunctivitis 80% of all acute conjunctivitis Serous Adenovirus in 65% of cases Cold compress

Artificial tears
Antihistamines

HSV 1.3-4.8% of all acute conjunctivitis Variable Herpes simplex virus Topical acyclovir 1 drop 9x per day for 7-10 days
Acute bacterial conjunctivitis 18.3%-57% of all acute conjunctivitis Mucopurulent Staphylococcus aureus, Staphylococcus epidermidis, Haemophilus influenzae

Streptococcus pneumoniae

Aminoglycosides

Ointment: qid for 1 wk Solution: 1-2 drops qid for 1 week
Fluoroquinolones

Ointment: Tid (three times a day) for 1 wk Solution: 1-2 drops Qid (four times a day) for 1 week

Allergic conjunctivitis Up to 40% of the population may be affected Serous or mucoid Pollen Topical antihistamines

Topical mast cell inhibitors

Do's

Don'ts

  • People with weaker immune systems such as those with diabetes and people who don’t wash their hands before inserting or removing contact lenses are more at risk of bacterial conjunctivitis.[14]
  • Patients with any form of conjunctivitis should refrain from wearing contact lenses until the conjunctivitis has completely cleared up.
  • Both types of infectious conjunctivitis are very contagious and easily spread. It is important to avoid contacting others or sharing equipment with other people to help prevent spreading the infection.
