INFLAMMATIONS OF CONJUNCTIVA

Inflammation of the conjunctiva (conjunctivitis) is
classically defined as conjunctival hyperaemia
associated with a discharge which may be watery,
mucoid, mucopurulent or purulent.

Etiological classification
1. Infective conjunctivitis: bacterial, chlamydial, viral, fungal, rickettsial, spirochaetal, protozoal, parasitic etc.
2. Allergic conjunctivitis.

3. Irritative conjunctivitis.
4. Keratoconjunctivitis associated with
  diseases of skin and mucous membrane.
5. Traumatic conjunctivitis.
6. Keratoconjunctivitis of unknown etiology.

Clinical classification
Depending upon clinical presentation, conjunctivitis
can be classified as follows:
1. Acute catarrhal or mucopurulent conjunctivitis.
2. Acute purulent conjunctivitis
3. Serous conjunctivitis
4. Chronic simple conjunctivitis
5. Angular conjunctivitis

6. Membranous conjunctivitis
7. Pseudomembranous conjunctivitis
8. Papillary conjunctivitis
9. Follicular conjunctivitis
10. Ophthalmia neonatorum
11. Granulomatous conjunctivitis
12. Ulcerative conjunctivitis
13. Cicatrising conjunctivitis
To describe different types of conjunctivitis, a mixed
approach has been adopted, i.e., some varieties of
conjunctivitis are described by their etiological names
and others by their clinical names.
