Trachoma is a bacterial infection caused by Chlamydia trachomatis that primarily affects the eyes. If left untreated, trachoma can lead to scarring of the eyelids and cornea, which can result in irreversible damage to the eye and ultimately lead to blindness.
The infection causes inflammation of the conjunctiva (the thin membrane that covers the white part of the eye) and the inner surface of the eyelids. Over time, repeated infections can cause scarring of the eyelids, which can lead to the eyelashes turning inward and scratching the cornea. This constant irritation and damage to the cornea can result in vision loss and blindness.
In addition, trachoma can also lead to complications such as corneal ulcers, corneal opacities, and trichiasis (ingrown eyelashes), all of which can further contribute to vision impairment and blindness if left untreated.

Trachoma causes blindness through a series of progressive stages:
1. Initial Infection:
- Chlamydia trachomatis bacteria infect the conjunctiva (clear membrane covering the front of the eye).
2. Inflammatory Response:
- The body's immune system responds to the infection, causing chronic inflammation of the conjunctiva (trachoma).
3. Repeated Infections:
- Repeated infections damage the conjunctiva, forming scars and thickening.
4. Formation of Trichiasis:
- Scars on the inner eyelid (trachomatous trichiasis) cause eyelashes to turn inwards towards the eyeball.
5. Corneal Abrasion:
- Inward-turned eyelashes constantly rub against the cornea (the clear front part of the eye), causing abrasions and scarring.
6. Corneal Ulceration:
- Ongoing abrasion leads to corneal ulceration, breaking down the corneal tissue.
7. Corneal Clouding:
- The damaged and scarred cornea becomes cloudy, impairing vision.
8. Visual Impairment:
- Severe corneal scarring can lead to visual impairment or blindness.
Additional Factors Contributing to Blindness:
- Poor hygiene and sanitation
- Crowded living conditions
- Lack of access to clean water and soap
- Flies, which can spread the bacteria
