The posterior annular compression test aims at estimating the aqueous outflow facility as well as at detecting the predisposition to the closure of the anterior chamber angle. An annular compressor weighing 50 g is placed on the globe in a posterior position to the iris‐lens diaphragm for 3 min. In 115 normal eyes the intra‐ocular pressure dropped after the test by 22 % or even more and the volume of the eyeball decreased not less than 5.5 mm 3 designing the limits for a negative test. In patients with open‐angle glaucoma the test was positive in 86 % of the 58 eyes examined. However, in all these cases a decrease of the intra‐ocular pressure occurred. The tension and the volume of the globe increased or remained unchanged in 35 eyes of the total of 52 with chronic closed‐angle glaucoma.
