Egyptian ophthalmia


Trachoma is an eye infection caused by bacteria.

Alternative Names

Granular conjunctivitis; Egyptian ophthalmia


Trachoma is caused by infection with the bacteria Chlamydia trachomatis. Symptoms being 5 to 12 days after being exposed to the bacteria. The condition begins slowly as conjunctivitis (irritation near the eye, "pink eye"), which if untreated may lead to scarring.

If the eyelids are severely irritated, the eyelashes may turn in and rub against the cornea. This can cause eye ulcers, further scarring, vision loss, and even blindness.

Trachoma occurs worldwide, primarily in rural settings in developing countries. It frequently affects children, although the consequences of scarring may not be seen until later in life. While trachoma is rare in the United States, certain populations marked by poverty, crowded living conditions, or poor hygiene are at higher risk for this illness.

Trachoma is spread through direct contact with infected eye, nose, or throat secretions or by contact with contaminated objects, such as towels or clothes. In addition, certain flies can spread the bacteria.


  • Conjunctivitis
  • Discharge from the eye
  • Swollen eyelids
  • Turned-in eyelashes
  • Swelling of lymph nodes just in front of the ears
  • Cloudy cornea

Exams and Tests

An eye exam may reveal scarring on the inside of the upper eye lid, redness of the white part of the eyes, and new blood vessel growth into the cornea.

Laboratory tests are needed to accurately identify and detect the bacteria and diagnose trachoma.


Antibiotics can prevent long-term complications if used early in the infection. Antibiotics include erythromycin and doxycycline. In certain cases, eyelid surgery may be needed to prevent long-term scarring, which can lead to blindness if not corrected.

Outlook (Prognosis)

Early treatment before the development of scarring and lid deformities has an excellent prognosis.

Possible Complications

  • Scarring of the conjunctiva and cornea
  • Eye lid deformities
  • Turned-in eyelashes
  • Vision loss -- if severe, may result in blindness

When to Contact a Medical Professional

Call your health care provider if you or your child recently visited an area of the world where trachoma is common and there are symptoms of conjunctivitis.


Improved sanitation and not sharing items such as towels are important measures for limiting the spread of trachoma.
