Filter by:Study aims for comparison of trabeculectomy and canaloplasty, in order to find out if one operation is superior to the other. Both procedures are performed in patients with medically uncontrolled open-angle glaucoma. Canaloplasty is a recently newly introduced procedure, which showed encouraging results without antimetabolite usage intra- and postoperatively. Purpose of the study is to compare both surgeries concerning success rate, intraocular pressure, medication and complications. So far there is no comparison of the standard procedure trabeculectomy and the new approach, canaloplasty available.
PURPOSE. To evaluate the impact of self-acting eyetracking and retest software on the reproducibility of retinal nerve fiber layer (RNFL) thickness measurements in glaucoma patients and healthy control subjects using Spectralis® SD-OCT. METHODS. RNFL thickness was measured in 56 normal and 47 glaucomatous eyes by one operator within one session with a brief rest between measurements. Three measurements were taken with the eye-tracker and retest function, and three were taken without this function, alternating between measurement methods. - Trial with medical device
The most common cause of post-trabeculectomy filtration failure is postoperative scarring. Long-term preoperative treatment with local antiglaucoma agents containing preservatives has an increased risk of post-operative scarring of the filtration bleb. Therefore many surgeons prepare their patients for planned trabeculectomy by discontinuing local antiglaucoma drugs, controlling IOP with oral acetazolamide, and treating the eye with local steroids. Preservative-free COSOPT-S® eye drops b.i.d now provide a possibility to reduce IOP preoperatively with the aim of avoiding postoperative excessive scarring and the known adverse effects of oral acetazolamide while achieving comparable IOP reduction and long-term outcomes. This study will investigate comparability (non-inferiority) of medical benefits of two different IOP lowering pharmaceutical interventions prior to trabeculectomy comparing COSOPT-S® bid to oral acetazolamide plus dexamethasone.
The aim of this study is to evaluate the tolerance and effect on unmedicated subjects with elevated IOP.
The objective of this clinical investigation is to determine the most effective drug concentration(s) of BOL-303259-X in the reduction of IOP in order to support further clinical development of an appropriate dose with regard to efficacy, and ocular and systemic safety.
The proposed human clinical studies have three main objectives: 1. To determine reproducibility of peripapillary birefringence maps and identify features that measure the health of the RNFL. 2. To determine the normal variation in the birefringence maps with age. 3. To develop and test a classifier for glaucoma based on the birefringence maps using a case-control clinical trial. This study is a case-control study intended to optimize feature selection for a future multi-center blinded study. The proposed clinical study does not measure conversion from normal to glaucoma.
This study will evaluate the safety and efficacy of Triple Combination Therapy compared with Fixed Combination brimonidine tartrate/timolol ophthalmic solution in patients with primary open-angle glaucoma or ocular hypertension.
This study will investigate the safety and efficacy of Triple Combination Therapy (bimatoprost/brimonidine tartrate/timolol fixed combination ophthalmic solution) in patients with glaucoma or ocular hypertension who have elevated intraocular pressure (IOP) on brimonidine/timolol ophthalmic solution.
This is an exploratory study that will evaluate the safety and pharmacodynamics of up to 3 doses of AGN-207281 based on an ongoing review of data during the study period compared with timolol ophthalmic solution or placebo in patients with ocular hypertension or primary open-angle glaucoma.
The primary objective of this study is to evaluate the safety, efficacy, and performance of the Suprachoroidal Dissection Instrument in creating a fistula between Schlemm's canal and the suprachoroidal space in refractory, open angle glaucoma subjects.
