    by the accumulation of albuminous exudation, probably vary in individual cases. A few inflammatory cases are the only ones that I can remember seeing after our own operations,* In a recent case the high tension was brought about by rapid ‘ exclusion of pupil,’ due to the irritation of some creamy, broken-down, cortical matter left behind the iris. The glaucoma was acute, and came on two days afterf the operation, which was a ‘ simple ’ extraction of a partly Morgagnian cataract. In some slight chronic rises of tension the cause may not be very apparent. The glaucoma may be evident as soon as Arm healing of the wound has taken place, or it may be found to be the cause of slow deterioration of sight long afterwards. A quite sudden rise of tension appears to be excited more frequently by needlings of after-cataract than by cataract extractions, and is not always readily explained. It may be the result of slight inflammatory reaction from the pull on the ciliary body, sufficient to bring into prominence a tendency to glaucoma already there, as a legacy from the extraction operation. And perhaps at times the setting free into the anterior chamber of some imprisoned cortical dehvis may act as it is liable to do in the discission of soft cataract. At other times neither of these accepted explanations will suffice. For instance, I lately provoked an attack of glaucoma in the eye of a boy by needling a capsular cataract, with very little imprisoned lens-substance, left after simple discission * Two patients operated upon in 1896, and two in 1897, came back later with glaucoma secondary to chronic iritis. But I believe no other similar cases have been seen of late years. This exemption is attributable to better management in preventing and controlling iritis. ^ t This very early onset of glaucoma is more common after simple extraction than combined (see Norris and Oliver’s ‘ System,’ iv. 392).
