“…A decrease in axial eye length due to lowered intraocular pressure has been shown in several previous studies [19][20][21][22][23] To our knowledge, this is the first study to demonstrate this effect after systemic administration of acetazolamide and the first to investigate the difference in rigidity between healthy and glaucomatous eyes in vivo. The resulting axial eye length decrease per mmHg IOP reduction was smaller for the glaucomatous eyes than for the healthy ones, suggesting that glaucomatous eyes are more rigid.…”

“…[16][17][18] Several studies have shown a decrease of axial eye length with lowered intraocular pressure after trabeculectomy. [19][20][21][22] A recent study by Leydolt et al 23 measured the change of axial eye length after mechanically inducing intraocular pressure elevation.…”

“…Reduction of axial length, as observed in successful trabeculectomies [4], may result in an increased OPA [14] and would therefore rather have hidden the OPA-lowering effect found in this study in patients with successful TE. To control for individual fluctuations of cardiovascular parameters such as heart rate or blood pressure, the changes in the OPA of the contralateral eye were used as controls.…”

“…A prospective study to determine the causes of changes in visual acuity after trabeculectomy reported an uncorrected Snellen acuity change in 94% of 16 patients and a corrected Snellen acuity change in 43% of these same patients 1 week after trabeculectomy [27]. Although the causes of these changes in visual function are unknown, it has been reported that trabeculectomy induces changes in several factors related to refraction, including corneal surface contour, anterior chamber depth, axial length, and lens thickness [11,12,[28][29][30][31][32][33][34][35][36][37]. In a number of studies, an increase in corneal astigmatism was reported in the early stages of trabeculectomy and was attributed to the use of cautery on the sclera and sutures of the sclera flap [11,12,28].…”
