Aim: This study examines the changes in axial length (AL) after trabeculectomy and glaucoma drainage device (GDD) surgery and enabled on equation to be derived allowing prediction of AL change after filtering surgery. Methods: This was a prospective, interventional case series from the Gloucoma Service of the Doheny Eye Institute. Patient population: One eye of 39 patients undergoing trabeculectomy and 22 undergoing Baerveldt tube shunt implantation for uncontrolled glaucoma. Intervention: These patients had AL measurements by non-contact, partial coherence interfermetry preoperatively, at 1 week, 1 mont, and > 3 months after surgery. Main aulcome measures: Axial length and intraacular pressure were compared at preoperative and postoperative visits. Postoperative intraocular pressure (IOP) was categorised as hypofonous (0-4 mm Hg), low (5-9), normal (10-17), and high (18 or more). Results: There was a statistically significant reduction in IOP after 3 months of -12.8 (SD 1.5) mm Hg following trobeculeclomy (p<0.001), and -10.7 (1.9) mm Hg after GDD (p< 0.001). There was a statistically signifcant reduction in AL, which was similar after trabeculectomy and GDD at all time points (p<0.001), of -0.15 (0.03) and -0.21 (0.04) mm (1 week), -0.18 (0.02) and -0.10 (0.02) mm (1 month), and -0.16 (0.03) and -0.15 (0.03) mm (3 months) [ABSTRACT FROM AUTHOR] |
