GRANULOMATOUS CONJUNCTIVITIS

Granulomatous conjunctivitis "granulomatous conjunctivitis contacts" is the term used to
describe certain specific chronic inflammations of the
conjunctiva, characterised by proliferative lesions
which usually tend to remain localized to one eye and
are mostly associated with regional lymphadenitis.

Common granulomatous conjunctival inflammations
are:

• Tuberculosis of conjunctiva
• Sarcoidosis of conjunctiva
• Syphilitic conjunctivitis
• Leprotic conjunctivitis
• Conjunctivitis in tularaemia
• Ophthalmia nodosa

Parinaud's oculoglandular syndrome
It is the name given to
  a group of conditions
characterised by:
1. Unilateral granulomatous conjunctivitis (nodular elevations surrounded by follicles),
2. Preauricular lymphadenopathy, and
3. Fever.
Its common causes are tularaemia, cat-scratch

disease, tuberculosis, syphilis and lymphogranuloma
venereum.
This term (Parinaud's oculoglandular syndrome)
is largely obsolete, since the infecting agents can
now be usually determined.

Ophthalmia nodosa (Caterpillar hair conjunctivitis)
It is a granulomatous inflammation of the conjunctiva
characterized by formation of a nodule on the bulbar
conjunctiva in response to irritation caused by the
retained hair of caterpillar. The disease is, therefore,
common in summers. The condition may be often
mistaken for a tubercular nodule.
Histopathological examination reveals hair
surrounded by giant cells and lymphocytes.
Treatment consists of excision biopsy of the nodule.
