THE INFECTIVE PROCESSES constitute by far the most important departures from the normal course of events after operation ; they are the most frequent cause of partial or complete failure to restore sight, and often also of greater or less destruction of the essential tissues of the eye. Besides the actual entrance of patho- genic bacteria of varying degrees of virulence, factors influencing the grade and extent of inflammatory reaction are those affecting the vitality of the tissues. The danger of operating upon the eyes of patients in the later stages of diabetes or nephritis, or in a state of extreme anaemia (see p. 14), is well recognised ; locally, the resistance to bacterial invasion may be lowered by excessive trau- matism. The open door provided for the admission of infective material by prolapse of iris or of vitreous is alluded to on pp. 44, 52, and 83. The most severe examples of the effects produced are grouped as Suppurations. Starting either as corneal
