trabeculectomy is the most common procedure performed in glaucoma patients to reduce intraocular pressure for a long-time period. this intervention can cause alterations in axial length (0.1-0.9 mm), anterior chamber depth (0.11±0.22 mm), and keratometry readings (1.07±1.14 diopter). these changes may linger for more than one year and may negatively affect the precision of intraocular lens powe...

AIMS To determine if post-trabeculectomy patching reduces the prevalence of shallow/flat anterior chambers and pain. METHODS 435 eyes were prospectively randomised to either a double patch with tape or no patch with tape group. RESULTS There was no statistically significant difference in flat or shallow anterior chamber rates or pain symptoms between the patch and no patch groups. CONCLUS...

Comment. Althoughhyphema isone of the most common early postoperative complications following trabeculectomy, to our knowledge, intralenticular collection of blood has not been previously reported. Because of the use of an operating microscope and the refinement of surgical techniques, lens injury during trabeculectomy has been infrequently reported. We hypothesized that there had been anterior...

Forty-six eyes with chronic open-angle glaucoma (COAG) and 24 eyes which had previously undergone trabeculectomy for COAG were studied and the postural response of the intraocular pressure compared with that of 70 normal eyes. In all three groups the greatest rise in intraocular pressure (IOP) occurred when the subject changed from the sitting to the lying position. In the control group this wa...

AIM Suture lysis is commonly performed after trabeculectomy to improve bleb function. It is often thought to be an innocuous procedure. This is the first large study to determine the safety of the procedure and compare results with a control group. METHODS Two hundred successive trabeculectomies performed between January 1992 and October 1993 were analysed. RESULTS Ninety nine eyes underwen...

OBJECTIVE To evaluate the long-term outcomes of three surgical procedures for the treatment of primary congenital glaucoma (PCG). INTRODUCTION PCG is one of the main causes of blindness in children. There is a paucity of contemporary data on PCG in China. METHODS A retrospective study of 48 patients (81 eyes) with PCG who underwent primary trabeculectomy, trabeculotomy, or combined trabecul...

PURPOSE To determine the effects of surgical IOP reduction (trabeculectomy) on retinal blood flow parameters in glaucoma patients using Dynamic Vessel Analysis (DVA). METHODS 26 eyes of 26 patients with progressive primary open-angle glaucoma (POAG) despite maximal topical therapy were examined before and after trabeculectomy. The responses of the retinal vessels to flickering light provocati...
