Ophthalmia nodosa
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.
