To the Editor:  Discussing his interesting findings, Dr. Ralph Kirsch (Arch Ophthal72:612-621, 1964) ventilated the question whether transient glaucomas occurring after the use of chymotrypsin during cataract surgery were due to hypersecretion or to retention of aqueous humour. It is difficult to speculate whether increased aqueous humour production can elevate the eye pressure as high as 60 mm Hg, the maximum observed by Kirsch, without simultaneous obstruction of outflow. However this may be, study of the aqueous veins during and after the episode of eye pressure increase could help to elucidate this problem.If the eye pressure increase is due to hypersecretion without outflow obstruction, the aqueous veins of the involved eye should show a more vigorous fluid elimination characterized biomicroscopically by a larger efflux of aqueous while the eye pressure is elevated and more frequent aqueous-influx phenomena during the phases of eye pressure increase. In retention glaucoma,
