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
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
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.
Uveitis
A type of eye inflammation that impacts the middle layer of tissue in the eye wall (uvea). Uveitis can be caused by infection, injury, or an autoimmune or inflammatory disease. It can be serious and lead to permanent vision loss, so early diagnosis and treatment are crucial.
- Vogt-Koyanagi-Harada Disease
This disease happens when the body's immune system mistakenly attacks a specific type of pigment cells called "melanocytes". The eyes are often affected, causing blurred vision, flashing lights, or floaters. Other areas that can be affected include the inner ear, causing hearing loss. The surface layer of the brain can also be affected, causing headaches and neck stiffness.
- Intraocular Foreign Body
- Behcet's Disease
- Corneal Injury
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
- Measles
- Stevens-Johnson Syndrome / Toxic Epidermal Necrolysis
Doctor's Diagnostic Questions

- Do you have bloodshot (red) eyes?
- Do you have red patches or bleeding spots in the white of your eyes?
- How long have you had redness in the white part of your eye?

I was actually very impressed with the results it provided because, although I didn’t mention it during the questionnaire because I thought it was unrelated, it suggested I may have something I’ve actually been diagnosed with in the past.
