Filter by:This is a randomized study with two treatment arms: 'initial Selective Laser Trabeculoplasty (SLT) followed by conventional medical therapy as required' ('Laser-1st') and 'medical therapy without laser ('Medicine-1st'). It compares quality of life in the two arms at three years, while also examining the incremental cost and cost-effectiveness of Laser-1st versus Medicine-1st.
The study will evaluate the efficacy and safety of MINIject 636 and IOP lowering effects with or without glaucoma medications. The procedure will be a stand-alone surgery. Overall, the patient will be asked to perform several examinations up to 24 months after surgery. The primary efficacy objective of the present study is to show the IOP reduction under medication 6 months after surgery compared to medicated diurnal IOP at screening.
Purpose: To investigate the effect of pseudoexfoliation (PEX) on choroidal thickness in primary open-angle glaucoma (POAG). Methods: This prospective, randomized study included 30 POAG patients and 30 PEX glaucoma patients with similar demographic characteristics, and 30 eyes of 30 healthy individuals comprised the control group. Macular choroidal thickness was measured using a Cirrus HD spectral domain optical coherence tomography (OCT) instrument.
Macular GCIPLT and vessel density will be measured with Spectralis optical coherence tomography and Topcon swept-source OCT respectively. Linear, quadratic and exponential regression models will be used to investigate relationship between GCIPLT and vessel density. Multilayer neural network will bel used to make single combined parameter and the diagnostic performance will be also compared.
The purpose of this study is to develop an educational program that will help improve the patients' understanding of what laser treatment is, how it might be beneficial to them, and why it should be the first eye pressure lowering glaucoma treatment to consider before the use of glaucoma eye drops.
This study evaluates the efficacy and tolerability of a new formulation of latanoprost without Benzalkonium Chloride (BAK-free). Patients with open-angle glaucoma who were using BAK-containing latanoprost ophthalmic solution for ≥6 months, switched to BAK-free latanoprost ophthalmic emulsion.
Perimetry is a well-established method that is used to measure the visual field functions of humans. Commercially available products, such as the OCTOPUS 900 (Haag-Streit AG, Koeniz, Switzerland), are commonly used for assessing the visual field. Such devices are of critical value for patients suffering of glaucoma and neuro-ophthalmic conditions. The operating principle is to sequentially present light stimuli of different intensity at different locations within the visual field in an automatic way. Algorithms that select what locations and intensities to present over time are called strategies. These have the goal to provide both a fast and accurate estimation of the visual field function. Recently, new strategies were developed that are faster and equally accurate as the strategies used today. The technological advancement of these new methods lies primarily in the ability to estimate location sensitivities without observing them directly but by leveraging previously queried locations. For this the investigators plan to implement the next generation of perimetry strategies into an OCTOPUS 900 and to test it in healthy subjects and glaucoma patients.
This study evaluates the possible acute changes in peripapillary blood flow after instillation of antiglaucoma medications in patients with primary open angle glaucoma (POAG), normal tension glaucoma (NTG), or ocular hypertension (OHTN) using Optical Coherence Tomography (OCT) angiography.
Glaucoma is the second leading cause of blindness worldwide. Literature shows increasing evidence that dysfunction of ocular microcirculation in the optic nerve influences the progression of glaucoma. Laser speckle flowgraphy (LSFG) represents a non-invasive method to quantify ocular perfusion also at the ONH. LSFG enables noninvasive quantification of microcirculation of the optic disc in Japanese glaucoma patients
The purpose of this study is to investigate how much selective trabeculoplasty (SLT) influences intraocular pressure (IOP) fluctuations measured with iCare Home rebound tonometry (RTHome) in patients with primary open-angle glaucoma (POAG) or pseudo-exfoliation glaucoma (PEX).
