When is red eye not just conjunctivitis?

Abstract

Red eyes are not 'just conjunctivitis' when there is significant pain or associated loss of sight. However, you are pretty safe to treat pain-free eyes and the normally seeing red eye with reasurance, lid hygiene advice and bland topical medication. But beware patients wearing soft lenses, and the red eyes of tiny babies or elderly patients, particularly those with apparent acute gastroenteritis.
