B94.0

Clinical Causes: Previous untreated or recurrent trachoma infections Chronic inflammation leading to scarring of the eyelids and cornea Repeated episodes of conjunctivitis caused by *Chlamydia trachomatis* Incomplete treatment or failure to address the infection adequately Poor hygiene and living conditions that promote transmission

Key Symptoms: Vision impairment or loss due to corneal scarring In-turned eyelashes (trichiasis) that irritate the cornea Corneal opacity and scarring Chronic conjunctivitis Irritation, redness, and itching of the eyes Light sensitivity (photophobia)

Diagnosis Path: Diagnosis of sequelae of trachoma generally involves a comprehensive eye examination by an eye care professional. The clinician will look for characteristic signs such as eyelid scarring, trichiasis, conjunctival scarring, and corneal opacity. Medical history regarding previous trachoma infection and exposure risk factors can support the diagnosis. In some cases, laboratory tests for *Chlamydia trachomatis* may be performed during active infection, but since sequelae develop after the infection ends, diagnosis primarily relies on clinical signs of eye damage and scarring.

Treatment Protocols: Management of trachoma sequelae focuses on preventing further damage, relieving symptoms, and restoring vision if possible. Typical approaches include: - **Surgical interventions** such as eyelid surgery for trichiasis to correct eyelash orientation and prevent corneal damage. - **Medical treatments** like lubricating eye drops to soothe irritation and reduce dryness. - **Management of inflammation** with appropriate anti-inflammatory medications. - **Preventive measures** including improved hygiene, facial cleanliness, and community health programs to reduce the risk of transmission. - **Regular eye check-ups** to monitor disease progression and address emerging complications promptly.
