Trachoma is caused by the bacteria Chlamydia Trachomatis. Trachoma, if left untreated, or treated late, can cause damage to the cornea, affecting the function of the eye.
1. What is trachoma?
Trachoma is considered a chronic inflammation of the conjunctiva and cornea. The cause of trachoma is caused by the bacterium Chlamydia Trachomatis, which is capable of causing disease in the eyes, genital tract in adults, respiratory tract and lungs in children.
In addition, many other micro-organisms can also cause trachoma such as:
Low and crowded living conditions: Low living conditions allow infectious bacteria to live and grow faster or live in poor conditions. Narrow spaces also have a higher risk of infection. Poor hygiene and sanitation: Poor hygiene and lack of hygiene, especially in the eyes, make it more susceptible to disease. Besides, not having a toilet or living in a place with many insects such as flies and mosquitoes makes the
disease easier to spread.

When trachoma, common lesions include:
Trachoma: Round in shape, raised on the surface of the conjunctiva or the edge of the cornea, gray-white, surrounded by blood vessels. Gonorrhea: This is a chronic inflammatory reaction caused by lymphocytes, plasmo... causing conjunctival edema, opacity, covering the underlying vascular system. . Papillary: Pink, vascular axis in the middle, radiating surrounding capillaries. This is vasodilation, proliferation of
capillaries and infiltration of inflammatory cells. Scar: This is a lesion of trachoma that has progressed for a long time. Usually in the upper eyelid cartilage conjunctiva, white fibrous bands are star-shaped, branched.
2. Trachoma symptoms and stages of development

Symptoms of trachoma include:
Mild itching and
irritation of the eyes and eyelids [swelling]; The eyes have a lot of discharge, containing mucus or pus. Sensitivity to light and eye pain. Glandular tissue that lubricates the eye, including the tear-producing glands, can be affected, leading to a worsening dry eye condition. Papillary and granular, often appear upper eyelid cartilage conjunctiva, lower eyelid conjunctiva may be, same pattern, irregular size. Some blood membranes appear in the cornea, the blood film is located in the
superficial layer and the upper part of the cornea. There are scars and pits on the cornea. The stages of development of trachoma include:
Trachoma follicle: At this stage, there are at least 5 granules on the upper eyelid cartilage conjunctiva, the size of which must be 0.5 mm. above. Trachoma follicle prevalence is indicative of the prevalence of trachoma in the community. Trachomatous inflamation Intense: The upper eyelid cartilage conjunctiva is infiltrated as red or thickened. That
gonorrhea obscures 1/2 of the blood vessels on the upper eyelid cartilage conjunctiva. Eyelid Scarring: When infection for a long time leads to scarring of the inner eyelid. The scars have white lines. Trichiasis: Scarring of the eyelids causes the eyelashes to grow inward and rub against the cornea. Corneal opacities: The cornea will be affected by inflammation. Inflammation leads to scratching leading to corneal clouding, secondary infection leading to corneal ulceration and possibly partial
or complete blindness.
3. Complications due to trachoma

People with trachoma can lead to complications such as:
Chronic conjunctivitis: Caused by red, itchy, lumpy eyes; Ingrown hairs, drooping hairs: Due to damage to the conjunctival margin of the eyelids, the eyelashes are crooked, deformed, constantly rubbing against the cornea, resulting in damage, scratches, corneal ulcers, corneal clouding. . Blindness: The main cause is poor hygiene, leading to bacterial infections that cause pyelonephritis. Inflammation of
the eyelid cartilage: Causes thickening of the eyelid margin, fibrosis, and deformation of the eyelid cartilage. Corneal ulcer: Causes eye pain, eye pain, photophobia, resulting in corneal distortion, astigmatism, corneal opacity and blindness. Superinfection: The main cause is trachoma, which makes the cornea damaged and susceptible to bacterial, viral and fungal infections, leading to corneal ulcers. Corneal granuloma: This granuloma can extend into the pupillary area and sometimes the entire
cornea. Astigmatism: Caused by calcifications and trachoma scars that rub on the cornea for a long time, causing the cornea to be jagged, misaligning the path of light, causing astigmatism, vision loss; Inflammation of the lacrimal gland, blocked tear duct: This complication can lead to blurred vision, watery eyes. Dry eyes, dry cornea: Due to atrophy of the ducts, decreased secretion, dry white eyes, blurred completely, can lead to corneal ulcers, corneal perforation and blindness.
4. Treatment and prevention of trachoma

Treatment of trachoma should follow the following regimen:
The antibiotic azithromycin [1 dose 1 year] is used in uncomplicated trachoma. This medicine kills the bacteria, then the eye will clear up on its own. When the disease is in the active phase, the patient should apply tetracycline 1% ointment or erythromycin every 8 hours and use it for at least 6 weeks. In addition to applying ointment, the patient needs to wash his face with soap and
water. Because the disease can cause very weak or almost no immunity, trachoma can still be re-infected after treatment. Therefore, if the patient has a complication of drooping hair, ingrown hairs, it is necessary to go to a doctor to have the doctor burn or pluck the hairs, surgery to pop the eyelashes out in the case of ingrown hairs.
Prevention of trachoma:
If you live in an area with trachoma epidemics, you need to keep clean, especially the eyes. Limit the sharing of cleaning
supplies. Improve living conditions: create clean water, kill flies. Water for personal hygiene must be clean.
