Undoubtedly, delayed re-formation of the anterior chamber or secondary loss of the anterior chamber following cataract extraction is in most instances only a mild complication. For example, Bellows and associates1 reported recently, in an excellent paper, that of 31 eyes exhibiting delayed re-formation of the anterior chamber, the chamber re-formed spontaneously in 27. Of 27 eyes showing a formed chamber following surgery with secondary loss of the chamber 4 to 15 days later, there was spontaneous re-formation in all but 20. In the delayed re-formation group, the four cases not cured spontaneously were successfully managed by repair of iris prolapse, in one case; by saline injection into the anterior chamber, in one case, and by air injection and posterior sclerotomy, in two cases. In the group with secondary loss of chamber, the two cases not cured spontaneously were successfully managed by air injection and posterior sclerotomy, in one case,
