Diagnosis of chronic conjunctivitis is carried out on the basis of the analysis of the complaints given biomicroscopy and a research of a refraction, bacteriological crops from a conjunctiva, statement . In treatment of chronic conjunctivitis elimination of the reason of an inflammation, local use of medicines of etiopatogenetichesky and symptomatic action has paramount value (a thaw, ointments).
Conjunctivitis makes about a third of all eye pathology in ophthalmology and is the most frequent inflammatory damage of eyes.

Can lead constant mechanical irritation of an eye to chronic conjunctivitis the foreign matters (which are incorrectly growing at eyelashes at a trikhiaza, grains of sand, particles of loose substances etc.).
Nekorregirovanny anomalies of a refraction (astigmatism, far-sightedness, presbiopiya), syndrome of a dry eye, snow blindness (elektrooftalmiya) can be the reasons of recurrent chronic conjunctivitis of a noninfectious etiology. The helminthic invasion, , seborrhea, chronic gastrointestinal diseases (gastritises, enetrokolita, cholecystitises), anemias, avitaminosis, a hyperglycemia and diabetes quite often acts as endogenous factors. On chronic type allergic conjunctivitis proceeds. In this case eye manifestations can be combined with allergic rhinitis, bronchial asthma, atopic dermatitis and have seasonal dependence.
Infectious chronic conjunctivitis can be caused by inflammatory diseases of eyes (blefarity, meybomeity, dakriotsistity), diseases of ENT organs (sinusitis, chronic tonsillitis, etc.). In certain cases leads inadequate treatment of sharp conjunctivitis to synchronization of process. In tsitogramma and crops from a conjunctiva at patients with chronic conjunctivitis staphylococcal flora, proteas, an enetrobakteriya, a pseudo-monad, moraksella, hlamidiya and pathogenic microorganisms usually comes to light.Please Help us - click on the advertisement

Chronic allergic conjunctivitis proceeds with education on a conjunctiva of nipples or follicles which are followed by an itch, sometimes – violation of sight and defeat of a cornea. In certain cases allergic conjunctivitis is combined with allergic dermatitis a century, blefarity, keratity, uveity, retinity, neuritis.

Vizometriya at chronic conjunctivitis can reveal decrease in visual acuity or its relative norm. At biomicroscopy changes of a conjunctiva and transitional folds come to light a century: insignificant hyperaemia, razrykhlennost, velvet of a surface, sosochkovy growths, etc.
For an exception of anomalies of a refraction the skiaskopiya and refractometry is carried out. At suspicion on the accompanying syndrome of a dry eye tests for a slezoproduktion research are carried out: Norn's test, Shirmer's test, flyuorestseinovy instillyatsionny test.
For definition of causative agents of chronic conjunctivitis carrying out bacteriological crops of dab from a conjunctiva is shown.
At the chronic conjunctivitis caused by associated diseases additional consultations (the otolaryngologist, the gastroenterologist, the endocrinologist, the dermatologist, the allergist) and a research can be required (a X-ray analysis of additional bosoms of a nose, from a nasopharynx; The REEF, PTsR, research IFA on clamidiosis; blood sugar definition, statement skin , a research of eyelashes on and so forth).Please Help us - click on the advertisement
