Which symptom is not associated with conjunctival infections?

1. Itching

2. Redness

3. Decreased visual acuity

4. Swelling of eyelids

The correct answer is: Decreased visual acuity

Decreased visual acuity is generally not associated with conjunctival infections. Conjunctivitis primarily involves the inflammation of the conjunctiva, which is the thin membrane covering the white part of the eye and the inner surface of the eyelids. Symptoms commonly include itching, redness, and swelling of the eyelids. While these manifestations can cause discomfort and irritation, they typically do not significantly impair vision. When a person experiences decreased visual acuity, it may suggest involvement of deeper ocular structures or more severe conditions such as keratitis (inflammation of the cornea) or other eye disorders. Therefore, visual acuity remains largely unaffected in cases of uncomplicated conjunctival infections. In summary, the nature of conjunctival infections focuses on surface symptoms like itching, redness, and eyelid swelling, without leading to a direct impact on visual clarity.
