In simple words: Trachoma is a contagious eye infection spread through contact with discharge from the eyes or nose of an infected person. It can also be spread by flies that have landed on infected secretions.Early on, it can cause pink eye. If not treated, it can cause scarring and even blindness. Other symptoms include eye pain, itching, pus, and sensitivity to light. Doctors diagnose it by asking about travel history, checking symptoms, examining the eyes, and testing eye discharge.

Trachoma is a contagious bacterial infection of the eyes caused by Chlamydia trachomatis. It spreads through contact with infected eye or nasal discharge, sometimes via flies.Initial symptoms can include conjunctivitis. If left untreated, it can lead to corneal scarring and blindness. Other symptoms include eye pain, itching, pus discharge, and light sensitivity. Diagnosis involves travel history, symptoms, eye examination, and laboratory tests of ocular discharge using nucleic acid amplification tests and PCR.

Example 1: A patient presents with eye redness, discharge, and itching after returning from a trip to a region where trachoma is endemic.A71.9 is used due to the nonspecific presentation, pending further tests., A child in a developing country exhibits signs of chronic conjunctivitis with early corneal scarring, suspected to be trachoma. A71.9 is used until the stage can be confirmed., A patient with a history of trachoma presents with severe corneal opacity, but the current stage of the disease is not specified in the documentation. A71.9 is applied.

Documentation should include signs and symptoms, travel history, examination findings, and laboratory results (if available) to support the diagnosis of trachoma.
