In 71 cases of primary open‐angle glaucoma and in 29 cases of angle‐closure glaucoma a sinus trabeculoectomy was performed and the biopsy specimens were studied by light microscopy. A control group included 100 cadaver eyes. The anterior position of Schlemm's canal prevailed in cases of open‐angle glaucoma (82%) and the posterior position of the canal was more common in cases of angle‐closure glaucoma (57%). In glaucomatous eyes, Schlemm's canal was narrowed and in some cases obliterated. In eyes with open‐angle glaucoma the mean diameter of scleral spur was 21.6 ± 4.22 microns as compared to 85.2 ± 2.76 microns in normal eyes and 70.5 ± 9.40 microns in eyes with angle‐closure glaucoma. In 100 eyes with open‐angle glaucoma and in 112 normal eyes the position of Schlemm's canal was estimated by gonioscopy. The anterior position of Schlemm's canal was found in 67% of all the cases with open‐angle glaucoma and in only 25% of normal eyes.
