Globally, what is the primary ocular problem caused by chlamydia affecting millions?

1. Conjunctivitis

2. Syphilitic retinopathy

3. Trachoma

4. Uveitis

The correct answer is: Trachoma

Chlamydia is a bacterial infection that has a significant impact on eye health, particularly in developing countries. The primary ocular problem associated with chlamydia that affects millions worldwide is trachoma. Trachoma is an infectious disease that leads to inflammation of the conjunctiva and cornea, which can eventually result in scarring and blindness if left untreated. Trachoma is primarily caused by repeated infections with the bacterium Chlamydia trachomatis and is prevalent in areas with poor sanitation and limited access to healthcare. It spreads through direct contact with the eye secretions of infected individuals and through flies that come into contact with these secretions. The symptoms may include itching and irritation of the eyes, and in severe cases, it can lead to entropion (inward turning of the eyelids) and corneal opacification. While other conditions mentioned, such as conjunctivitis, syphilitic retinopathy, and uveitis, are important to recognize in ophthalmology, their associations with chlamydia are not as globally prevalent as trachoma. For example, conjunctivitis can be caused by various factors, including allergies, viruses, and bacteria, but it does not specifically highlight the burden of chlamydia on a
