purpose: to describe the biometric changes and their effect on intraocular lens (iol) power calculation after trabeculectomy and to compare the accuracy of four formulas namely srk/ii, srk/t, holladay and hoffer q for iol power calculation in these patients. methods: thirty-four eyes of 31 glaucoma patients who were scheduled for primary trabeculectomy were enrolled. a non-contact biometry devi...

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...

BACKGROUND The objective of the study is to examine the effect of trabeculectomy on intraocular lens power calculations in patients with open-angle glaucoma (OAG) undergoing cataract surgery. DESIGN The design is retrospective data analysis. PARTICIPANTS There are a total of 55 eyes of 55 patients with OAG who had a cataract surgery alone or in combination with trabeculectomy. METHODS We ...

OBJECTIVE To determine whether the timing of cataract surgery after trabeculectomy has an effect on trabeculectomy function in terms of intraocular pressure control. METHODS This was a cohort study nested within a randomized clinical trial. There were 235 participants with glaucoma who had a single previous trabeculectomy augmented with either intraoperative 5-fluorouracil or placebo. Catarac...

PURPOSE To compare the surgical results of trabeculectomy and Ahmed glaucoma valve implantation after a previous failed trabeculectomy. METHODS A retrospective comparative case series review was performed on 31 eye surgeries in 20 patients with primary congenital glaucoma who underwent trabeculectomy or Ahmed glaucoma valve implantation after a previous failed trabeculectomy with mitomycin C....

purpose : to compare the effectiveness and safety of trabeculectomy with mitomycin c (mmc) versus trabeculectomy with oculusgen methods : in this prospective study 14 eyes of 7 patients with a diagnosis of primary open angle glaucoma (poag) that required trabeculectomy for both eyes were enrolled. for each patient we randomly performed trabeculectomy with mmc for one eye and trabeculectomy with...

purpose : to assess the efficacy and safety of sutureless punch trabeculectomy as substitute for conventional scleral flap trabeculectomy. methods : in a prospective, randomized study, 44 eyes of 42 patients with primary open angle glaucoma (poag) who were candidate of trabeculectomy were included and randomly assigned into two groups sutureless punch trabeculectomy or conventional scleral flap...

BACKGROUND The treatment for infantile glaucoma is surgical. Treatment options include goniotomy, trabeculotomy, combined trabeculotomy-trabeculectomy, and trabeculectomy. METHODS Patients who had a follow up of 5 years or longer after primary trabeculectomy were examined to determine the long term stability in infantile glaucoma. RESULTS In eyes with primary infantile glaucoma 92.3% achiev...

Trabeculectomy is the gold standard procedure performed in glaucoma when topical medication and laser intervention failed. In a trabeculectomy, number of clinical trials have shown efficacy ranibizumab minimizing extracellular matrix accumulation at filtering site. Ranibizumab (LucentisTM) drug that targets vascular endothelial growth factor (VEGF). However, to date actual mechanisms this anti-...

to compare the success of patients with ocular hypertension, secondary to pars plana vitrectomy and silicon oil tamponade, who had an ex-press glaucoma filtration device p50 (alcon laboratories, inc. fort worth, texas, usa) to those who had conventional trabeculectomy this study has been performed. the records of 10 eyes of 10 consecutive subjects who had ex-press implants and 9 eyes of 9 conse...
