Acute red-eye

An acute red eye is a vital sign of ocular inflammation. The most common cause of a red eye is conjunctivitis which can be either bacterial or viral. Other common causes include corneal abrasion, foreign body, chemical burn, blepharitis, iritis, keratitis, scleritis, subconjunctival hemorrhage, and glaucoma. In combination with the red-eye, you may experience an ocular discharge, pain, itchiness, visual changes, and photophobia. The treatment of an acute red eye will be determined by the cause; thus, it is best to consult with an ophthalmologist.
