Secondaryglaucoma is likely to follow, and thetension of the globe should, there-fore, be carefully noted wheneverthis bulging is present. Totalposterior synechia always shows asevere, though often a chronic,iritis; it is often accompanied bydeep-seated disease, and followedby opacity of the lens (secondarycataract), and in some cases ulti-mately the lens becomes of iritis are believed to beinduced by the presence of synechise,even when there is no protrusion ofthe iris by fluid ; but their influ-ence in this direction has, I believe,been much overrated. occluded/ thecollects m the. Fig. 54 — Dia-gram to showbulging of irisby collection ofaqueous humourbehind it, whenthepupillarybor-der of the iris iscompletely adhe-rent to the lens-capsule (exclu-sion of pupil). It must, however, be observed that there is still much differ-ence of opinion on the point last referred to. The iritis ofsyphilis is still held by some to be very liable to recur, and tobe by no means limited to the secondary stage; and we stilloften hear it stated that iritic adhesions, by preventing freemovement of the iris, operate as sources of irritation, and thuspredispose to relapse. I have seldom succeeded in getting ahistory of recent syphilis in cases of recurring iritis, whilstin a number of cases of old iritis with the history of in-flammation during secondary syphilis years before, I havescarcely found one with well-marked history of relapses. Lastly,I have several times seen severe relapses in rheumatic cases afteriridectomy had been performed
