Chlamydia are Gram-negative bacteria adapted to intracellular life. Three species have been identified within this genus: Chlamydia psittaci (causes ornithosis in humans), Chlamydia pneumoniae (associated with respiratory infections), and Chlamydia trachomatis (responsible for urogenital infections). Chlamydia trachomatis also causes chlamydial conjunctivitis (inclusion conjunctivitis). Inclusion conjunctivitis occurs most often in younger individuals, and infection occurs sexually or through the transfer of chlamydia from one's own genitals on the hands (self-infection). In Poland, chlamydial conjunctivitis is relatively rare. However, the disease occurs more often than it is diagnosed.
Characteristic symptoms include mucopurulent discharge and a papular reaction, as well as a chronic, recurrent course of the infection.
Inflammation usually affects one eye and manifests as mucopurulent discharge and a papular reaction of the conjunctiva, particularly in the inferior fold of the conjunctival sac. The eyelids are swollen, and the parotid lymph nodes are enlarged and painful. Typically, this inflammation is chronic, with periods of exacerbation and remission lasting up to several years. Some patients may develop keratitis, the development of pannus (subepithelial proliferation of vessels and fibrous tissue) in the upper part of the cornea, and conjunctival scarring. If the lesions involve the central part of the cornea, they can cause decreased visual acuity. Conjunctivitis is usually accompanied by vaginal
and cervical inflammation in women and urethral inflammation (sometimes asymptomatic) in men. The diagnosis can usually be made based on the patient's history and a biomicroscopy (slit lamp) examination of the eyes.
Laboratory tests can be performed on a conjunctival swab to confirm the diagnosis. genetic PCR. Since chlamydial infections are sexually transmitted, it is important to remember
to examine and possibly treat the partner of the infected person.

Pursuant to the Regulation of the Minister of Health of June 26, 2020 (Journal of Laws of 2020, item 1118), a positive test result is subject to mandatory reporting by the laboratory performing the test to the District Sanitary and Epidemiological Station.
