Reduced variation of the diurnal curve after the subscleral scheie procedure for primary open-angle glaucoma

We report the results of a one-year prospective study of the maximum intraocular pressure and the range of the oscillations of the diurnal curve after a subscleral Scheie procedure in 21 eyes (13 patients) with chronic primary open-angle glaucoma. Pressure curves were recorded preoperatively, during the immediate postsurgical period, at one month postoperatively, and every three months thereafter up to one year after surgery. Our results showed that this procedure reduced the maximum intraocular pressure and the oscillations of the diurnal curve (P < .001). This effect was maximum during the immediate postoperative period and decreased one month after surgery (P < .001).
