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.

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.

The difference between trachoma and stye

Trachoma is a chlamydial infection, while a stye is an infection caused by Staphylococcus aureus. Trachoma manifests as the formation of trachoma follicles, hyperplasia, and inflammation on the inner surfaces of the eyelid and conjunctiva, with symptoms including redness, swelling, pain in the eyes, neovascularization of the cornea, and vascular pannus. A stye presents with redness, swelling, heat, and pain in the eyelid, mainly caused by inflammation. In terms of treatment, trachoma mainly uses rifampin eye drops; styes are treated with levofloxacin eye drops, and erythromycin or tobramycin ointment at night, with no hot compresses applied. Typically, a stye can heal within about a week, whereas trachoma requires a longer treatment period, and it is important to rest and undergo regular check-ups. (The use of medications should be carried out under the guidance of a physician)

How to eliminate trachoma follicles

Trachoma follicles need to be treated regularly with antibiotic eye drops to kill the Chlamydia trachomatis and eliminate inflammation before they can be resolved. Trachoma is a common ophthalmic disease caused by neglect of eye hygiene, such as rubbing the eyes with dirty hands, leading to the infection of the conjunctival tissues by Chlamydia trachomatis. The typical symptoms include eye congestion, redness, increased discharge, and a foreign body sensation. By using a slit lamp microscope for magnified observation, the doctor can see numerous follicles and scar formation on the inner surface of the patient's eyelid, as well as vascular pannus formation at the corneal limbus. Treatment involves using eye drops such as levofloxacin hydrochloride, rifampicin, and sulfacetamide sodium to kill the pathogen and thereby alleviate the symptoms. (Please follow medical advice regarding medication.)

Trachoma has several treatment methods.

Trachoma is a chronic infectious conjunctival and corneal inflammation caused by Chlamydia trachomatis infection and is one of the leading causes of blindness. Around three hundred to six hundred million people worldwide are infected with trachoma. Treatment includes systemic and local ocular medication, as well as treatment for complications. Local treatments include 0.1% rifampicin eye drops, 0.1% tetrahydropalmatine eye drops, or 0.5% neomycin eye drops. Erythromycin or tetracycline eye ointments are used at night, with a treatment duration of at least ten to twelve weeks. Acute or severe cases of trachoma should be treated with systemic antibiotics. Surgical correction of trichiasis and entropion is crucial to prevent late-stage trachoma scarring that leads to blindness.

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.
