title: The red eye. Why it happens, what to do, when to refer.
abstract: The ability to differentiate the various causes of ocular hyperemia is important in primary care. Symptoms such as pain, photophobia, and significant blurring of vision usually signify a more serious ocular condition or even a serious systemic disease. The majority of cases can be managed by the primary care physician, but the more serious causes of a red eye deserve prompt recognition and referral to an ophthalmologist to ensure appropriate management.
