[In vivo-measurements of the latitude of Schlemm's canal in buphthalmos (author's transl].
In 9 cases of buphthalmos 'in vivo-measurements of the latitude of Schlemm's canal gave us a mean value of 678 micron. The extreme values ranged between 600 micron and 800 micron. Therefore these values differ significantly from those measured 'in vivo' in chronic simple glaucoma (x:542 micron, extreme values 425 micron and 625 micron). The latitude of Schlemm's canal correlates with the diameter of cornea and the rise of intra-oculare pressure. In cases of buphtha-mos the success of trabeculotomy seems to be better, if the latitude of Schlemm's canal is less than l50 micron. Trabeculotomy should therefore be performed as soon as possible.
