title: The red eye.
abstract: A red eye is a cardinal sign of ocular inflammation. Most cases are benign and can be managed by the primary care provider. The key is recognizing cases requiring ophthalmological consultation by differentiating between ciliary and conjunctival injection. Ciliary injection indicates inflammation of the cornea, iris, or ciliary body, whereas conjunctival injection mainly affects the posterior conjunctival blood vessels.
