This document provides a differential diagnosis for red eye and lists the most common causes. It discusses four important causes in more detail: acute adenoviral conjunctivitis, acute bacterial corneal ulcer/keratitis, acute anterior uveitis, and acute congestive glaucoma. For each cause, it outlines characteristics of vision, eyelid swelling, discharge, congestion, cornea appearance, anterior chamber reaction, pupil appearance, intraocular pressure, and whether referral is required.
