Mostly acute onset, the patient has foreign body sensation, photophobia, tears, a lot of mucus or mucous secretions. A few weeks after the acute symptoms subsided, into the chronic phase, this time without any discomfort or only easy to feel tired. If at this time to cure or self-healing, can not leave scars. However, in chronic disease, in the popular areas, often repeated infection, exacerbations. Corneal with active pannus, the irritation becomes significant, vision loss. Late often due to sequelae, such as eyelid varus, trichiasis, corneal ulcers and dry eye, the symptoms are more obvious, and seriously affect the vision, or even blindness.
2, signs
⑴ acute trachoma: showing the symptoms of acute follicular conjunctivitis, eyelid swelling, conjunctival hyperemia, due to nipple hyperplasia eyelid conjunctiva rough, upper and lower dome conjunctiva follicular follicles, combined with diffuse keratitis and anterior lymphadenopathy. After a few weeks of acute inflammation subsided, to chronic phase.
⑵ chronic trachoma: may be due to repeated infection, duration of several years to more than 10 years. Although the degree of congestion is reduced, but with subcutaneous tissue diffuse cell infiltration, conjunctiva was fouling hypertrophy, while nipple hyperplasia and follicular formation, follicular size ranging from plastic samples can be above the dome and tarsal upper conjunctiva significantly The The same lesion is also found in the lower palpebral conjunctiva and the lower dome conjunctiva, severe cases can even invade half of the wrinkles. Corneal pannus: it is from the cornea outside the normal capillary network, through the corneal limbus into the transparent cornea, affecting vision, and gradually to the pupil area development, accompanied by cell infiltration and development of shallow ulcers, healed after the formation of cornea Small face. Cell infiltration can form a thick flesh-like pannus (pannus crassus).
3, trachoma follicles
In the chronic disease, conjunctival lesions gradually replaced by connective tissue, the formation of scar. The earliest appeared in the upper eyelid conjunctiva under the tarsus, was horizontal white stripes, then gradually reticular, until the active lesions completely subsided, the lesion conjunctiva all become white smooth scar.
4, trachoma scar
The course and prognosis of trachoma, due to the severity of infection and whether the repeated infection is different. Light or no repeated infection, a few months can be more, conjunctival left scar or no obvious scar. Repeated infection of critically ill patients, the course of disease can be lingering for several years to 10 years, chronic diseases, can be infected by other bacteria and repeated infection is often an acute attack. Finally, a wide range of scar is no longer contagious, but there are serious complications and sequelae, often make vision loss, or even blind.
