SINCE narrow-angle glaucoma was described by Barkan (1938), conflicting opinions have been expressed as to the correctness of his views. Barkan postulated, and many authors have since agreed with him, that the rise in intra-ocular pressure in the condition usually known as congestive glaucoma, is due to mechanical obstruction to the outflow of aqueous at the filtration angle of the anterior cha...

THE significance of pigmentation of the anterior segment of the eye in the development of glaucoma, especially in the area of the trabecula of the chamber angle, has been studied by many authors. von Hippel (1901) considered that glaucoma was due to obstruction of the chamber angle with pigment (Hanssen, 1923). Levinsohn (1908) microscopically established infiltration ofthe chamber angle by pig...

Purpose. To compare the changes of anterior segment parameters, assessed by swept source anterior segment optical coherence tomography (AS-OCT) after combined Trabectome-cataract surgery and Trabectome-only surgery in open angle glaucoma patients. Methods. Thirty-eight eyes of 24 patients with open angle glaucoma were scanned with swept source AS-OCT before and 4 weeks after combined Trabectome...
