Description

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.

  • Vogt-Koyanagi-Harada disease

    This disease occurs when the body's own immune system accidentally attacks a particular type of pigment cells called "melanocytes". The eyes are often affected, causing blurring of vision, flashing lights, or floaters. Other areas that can be affected include the inner ear, causing loss of hearing. The surface layer of the brain can also be affected, causing headaches and neck stiffness.

  • 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. When a person is infected for a second time, this is associated with more severe disease because the antibodies produced from the first infection cross-react with the new virus. Severe forms of dengue fever can be fatal.

  • Pharyngoconjunctival fever
  • Sjogren syndrome
  • Herpes simplex
