Among 2,700 babies born in a maternity hospital there were 71 (2.6%) cases of eye sepsis, mostly mild. Forty-four of these cases were screened for inclusions of TRIC agent. Four certain positives and a further four very suggestive cases were found-an incidence of 18% of the cases of eye sepsis investigated. The true incidence is probably somewhat higher.Follow-up showed that even minimal and transitory eye sepsis from TRIC infection in the neonate can lead to permanent scarring of the conjunctiva and cornea, with or without pannus.
