About the Symptom
Bloodshot eyes refers to redness or pinkness of the eye, usually the entire eye. This can be due to trauma, infection, dry eyes, or other medical conditions

Possible Causes
Generally, Bloodshot eyes can be related to:
- Pharyngoconjunctival Fever
This viral infection causes sore throat, red eyes, and fever. Some patients may have enlarged neck glands (lymph nodes). Patients usually recover without treatment.
- Intraocular Foreign Body
Intraocular foreign bodies are unintentional projectiles that are retained in the eye and require urgent diagnosis. If left unattended, they may lead to vision loss and blindness.
- Corneal Injury
Corneal damage is an injury to the cornea, which is the transparent tissue covering the front of the eye.
- Uveitis
- Vogt-Koyanagi-Harada Disease
- Behcet's Disease
Related Serious Diseases
Sometimes, Bloodshot eyes may be related to these serious diseases:
- Acute Glaucoma Attack
A condition caused by high pressures in the eyeball, more common in people with farsightedness. Persons of Black, Asian, or Hispanic descent are at higher risk. The high pressures can cut off blood flow to the eye. Prompt medical attention is needed to prevent permanent blindness.
- Kawasaki Disease
- Stevens-Johnson Syndrome / Toxic Epidermal Necrolysis
- Measles
