Trachoma is caused by Chlamydia infection, while eye concretions are generally caused by chronic inflammation leading to lipid accumulation. When the eyelids show symptoms of trachoma, proliferative follicles and proliferative tissues in the eyelids form cobblestone changes. The concretions are white and located subconjunctivally, generally deep enough not to affect the eyes, but if superficial, they protrude into the palpebral conjunctiva and can cause certain wear to the eyes. Symptoms such as a foreign body sensation, burning sensation, and increased secretions can result from both trachoma and eye concretions. For treatment, eye drops are used for trachoma, and the eye concretions are removed under topical anesthesia, which alleviates the symptoms.

The positivity for Chlamydia trachomatis is caused by what reason?

Chlamydia trachomatis is the main source of infection causing trachoma. There are many reasons that can lead to a positive test for Chlamydia trachomatis, mainly the following three points. These are poor hand hygiene of the patient, improper cleaning of the eyes, and infection by Chlamydia trachomatis in public areas. In fact, the primary reason is still the individual's failure to maintain proper hygiene practices. When symptoms of trachoma appear, it is necessary to seek medical attention promptly. Once diagnosed as positive for Chlamydia trachomatis, one should pay more attention to rest and eye hygiene. It is essential to maintain good hygiene habits regularly, and it is best to engage in some physical exercise, which can help strengthen the body's immune system.

How is trachoma transmitted?

Trachoma is somewhat contagious. When it is confirmed as trachoma, the eyelids and the conjunctiva of the eyes will carry the bacterium due to Chlamydia infection. When patients touch their eyes with their hands, their fingers or palms are already carrying the bacteria, including Chlamydia. Therefore, when they come into contact with others, cross-infection can occur. Prevention of trachoma primarily involves avoiding contact infection, improving environmental hygiene, enhancing the sanitary management of service industries such as hotels, swimming pools, and barber shops, and developing good hygiene habits, including avoiding rubbing the eyes with hands.

Trachoma is what type of infectious disease

Trachoma is classified as a Class C infectious disease by national regulations. Trachoma generally manifests as red eyes, swollen eyes, eye pain, increased secretions, and a foreign body sensation, sometimes affecting vision. The conjunctiva in trachoma shows significant proliferative follicles, or pavement stone-like changes. The transmission of trachoma is mainly through contact. Additionally, it is categorized as a Type C infectious disease, with infectious diseases classified into three major categories: Type A, Type B, and Type C. After contracting trachoma, it is crucial to actively treat it with eye drops and to pay attention to eye hygiene.

Does trachoma need treatment?

Trachoma is a chronic infectious conjunctivitis that can lead to blindness, so once diagnosed with trachoma, it is essential to undergo both systemic and local drug treatment. Systemic treatment includes the acute phase, where severe trachoma requires systemic use of antibiotics, generally for three to four weeks. Local treatment involves the application of rifampin, penicillin, and other eye drops, and erythromycin eye ointment, etc., for at least ten to twelve weeks. If complications such as entropion, trichiasis, ptosis, symblepharon, or chronic dacryocystitis occur, surgical correction is necessary.

Can trachoma wear colored contact lenses?

The eyes themselves already have trachoma, which is one of the contraindications for wearing contact lenses. Therefore, based on the current health condition of the eyes, it is not suitable to fit contact lenses. Since the eyes already have an infectious disease, wearing cosmetic contacts, which contact the cornea, can easily lead to the occurrence of keratitis and worsen the inflammation. It is necessary to visit a professional ophthalmologist for examination and treatment of the trachoma. After the treatment is completed, then consider the issue of fitting contact lenses.
