The authors evaluated the relationship between the development of filtering bleb and the thickness of the aqueous drainage route beneath the scleral flap in patients who had undergone trabeculectomy. The relationship between the postoperative intraocular pressure and the size of the filtering bleb was also studied. They studied 29 eyes of 21 patients who had been followed for at least one (mean 9.9) month after the trabeculectomy. Ultrasound biomicroscopy was used to examine the filtering bleb and aqueous drainage route beneath the scleral flap. The thickness of the aqueous drainage route beneath the center of the scleral flap was found to be correlated with the development of a filtering bleb (r = 0.391, p < 0.05). The size of the bleb was correlated with the intraocular pressure (r = -0.560, p < 0.05) which had not been treated with anti-glaucoma medication during follow-up. Thus, preservation of the aqueous drainage route beneath the scleral flap probably influenced the development of a filtering bleb following trabeculectomy.
