Signs and symptoms of discomfort, mucopurulent ocular discharge, and conjunctival redness are common in benign cases and often lead to absence from work and school to minimize the risk of infection to others. Morbidity can be associated with misdiagnosis. Since many eye diseases cause the eye to be red, it is beneficial to have a solid clinical approach to differential diagnoses of the red eye, as well as an effective referral paradigm in the primary care setting. Diagnoses often missed by non–eye-care providers (providers other than ophthalmologists and optometrists) include acute glaucoma; iritis; bacterial, fungal, and parasitic keratitis; corneal foreign bodies; conjunctival and tarsal foreign bodies; herpetic dendritic keratitis; scleritis; and subconjunctival hemorrhage, among others.
