Overview

Conjunctivitis may be classified based on the duration of symptoms into hyperacute, acute, and chronic.[1][2] Additionally, conjunctivitis may be classified according to the causality of the inflammation or age groups into several subtypes: infective conjunctivitis (bacterial and viral), neonatal conjunctivitis (ophthalmia neonatorum), allergic conjunctivitis, keratoconjunctivitis sicca (dry eye syndrome), superior limbic keratoconjunctivitis, and chemical conjunctivitis.[3][4]

Classification

Based on the duration of symptoms, conjunctivitis may be classified into hyperacute, acute (less than 3 weeks), and chronic (greater than 3 weeks).

According to the etiology and age groups, conjunctivitis may be classified into:[5][6][7] [8]
