    ciliary processes, especially wlien tlie capsule is tough, not diaphanous, but forming an opaque membrane or present- ing opaque stripes. Mr. Priestly Smith,* in 1879, recorded a case of glau- coma following extraction of senile cataract, and in treat- ing of the case summarizes the process as follows : The lens is removed without rupture of the suspensory ligament and capsule ; plastic iritis, possibly due to the retention of cortical fragments, sets in ; the iris adheres throughout to the suspensory ligament and capsule ; the portions of these membranes occupying the pupil and the coloboma are coated over with lymph. A thickened im- pervious partition is thus created between the aqueous and vitreous chambers; the tension rises in the vitreous chamber ; the angle of the anterior chamber is closed by the advance of the partition; a certain amount of turbid fluid is imprisoned in the anterior chamber, intense glau- coma is rapidly induced. Stolting,t in 1887, recorded a case of glaucoma follow- ing linear extraction in a woman set. 64, in which he af ter- wards made a pathological examination of the eyeball. In this case there was incarceration of the lens capsule and iris in the extraction cicatrix, and the angle of the anterior chamber was closed by peripheral adhesion of the iris throughout the whole circle. HeJ holds that the starting-point of the glaucoma in his case was a traumatic choroiditis; that the onset of glaucomatous tension was the expression of lymph-stasis between choroid and sclera; that the final result of the glaucomatous pressure was the closure of the angle of the anterior chamber. Schlegtendal,§ in commenting on this case, urges that ^Hhe evidence in favour of the supra-choroidal cedema is fallacious ; in short, that the appearances described were produced artificially after the excision of the eye. * ' Glaucoma; its Causes, &c.,' p. 178. ■f ' Archiv f.
