Overview

Red eye is an essential sign of eye inflammation. Although it is usually benign and can be managed by primary care physician, It is important to distinguish between benign and sight-threatening diagnoses. Its most common cause is conjunctivitis. However, the other common causes are subconjunctival hemorrhage, blepharitis, scleritis, corneal abrasion, glaucoma and foreign body. Red eye can be concomitant photophobia, eye discharge, pain, itiching and visual changes.
