Chlamydia trachomatis infection of the conjunctiva leads to Chlamydia trachomatis conjunctivitis, a chronic infectious keratoconjunctival inflammation, which was very common in the past, mainly due to poor personal or collective hygiene conditions, and is now relatively uncommon. Symptoms of the disease include conjunctival papillae, follicle formation, epithelial keratitis, or formation of vascular opacities at the corneal limbus, all of which are typical symptoms of trachoma. The most commonly used drugs for trachoma treatment are rifampicin, sodium sulfacetamide and phthalidone drops, which are used for 1-3 months.
