About the symptom

Bloodshot eyes refers to redness or pinkness of the eye, usually the entire eye.

When to see a doctor

Seek professional care if you experience any of the following symptoms

  • Edema

  • Eye pain

  • Fever

  • Visual field defect

  • Photophobia

  • Dysphagia

  • Muscle pain (myalgia)

  • Erythema

  • Conjunctival redness

Possible causes

  • Allergic rhinitis / allergic conjunctivitis (including spring catarrh)

    A condition caused by allergens (substances that cause allergies) such as pollen and dust mites. These result in runny nose, stuffy nose, sneezing, and itching of the eyes.

  • Dengue fever

    This is caused by the dengue virus, carried by infected Aedes mosquitoes. There are 4 subtypes of dengue virus. Infections are more severe among immunocompromised people, the elderly, and young children. If a person is infected for a second time, this can be associated with more severe disease, because the antibodies produced from the first infection can cross-react with the new virus. Severe forms of dengue fever can be fatal.

  • Pharyngoconjunctival fever

    This is a viral infection causing sore throat, red eyes, and fever. Some patients may have enlarged glands (lymph nodes) in the neck. Patients will recover without treatment by themselves.

  • Sjogren syndrome
  • Vogt-Koyanagi-Harada disease
  • Herpes simplex
