What would a physical exam reveal in case of conjunctival injection?

In the case of conjunctival injection, a physical exam would reveal redness of the conjunctiva. Conjunctival injection occurs when the blood vessels in the conjunctiva become dilated and more prominent, leading to the characteristic reddening of the eye. This condition is often a sign of irritation, inflammation, or infection, and it is a common finding in various ocular conditions.

The redness is typically diffuse and can vary in intensity based on the underlying cause. Conditions such as conjunctivitis, allergic reactions, and other irritations can lead to this observable sign during a physical examination. It’s important for healthcare professionals to recognize this symptom, as it guides further evaluation and management of the condition affecting the patient's eyes.

In contrast, the other options indicate normal or opposite findings, making them inconsistent with what is observed in cases of conjunctival injection. Normal visual acuity may be present in some cases, but it is not a direct reflection of the conjunctival status.
