Filter by:This study will evaluate the safety and IOP-lowering effectiveness of XEN in patients with Angle Closure Glaucoma.
Evaluation of adherence to clinical treatment of glaucoma in patients of a Reference Ophthalmological Hospital in Goiânia using Morisky Adhesion scale as a validated questionary.
The aim of this study is to measure fitness to drive in patients with a visual and a cognitive impairment. To do so, Ocusweep is used in patients with glaucoma and Mild Cognitive Impairment. The participants will be divided over four groups; patients with glaucoma, patients with cognitive impairment, patients with both and a healthy control group. Differences in performance on Ocusweep in the four different groups of participants are expected. These effects may be related to fitness to drive, which is why those results will be compared to traditional neuropsychological measures of fitness to drive. the hypothesis of the current study is that the Ocusweep performance is related to performance on other measures of fitness to drive.
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.
The purpose of this trial is to evaluate the performance of a new diagnostic device in the diagnosis and management of glaucoma. We will use this new device (PERG) to evaluate the function of the retina in glaucoma patients. This device is safe for the patients.
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.
Primary angle-closure glaucoma (PACG) is common, phacotrabeculectomy is associated with a significant risk of complications.The Ex-PRESS shunt was introduced as a modification to trabeculectomy, with the theoretical advantages of reduced complications.Our purpose is to perform a prospective study to evaluate the clinical outcomes and safety of the Ex-PRESS shunt with cataract surgery for PACG patients coexisting cataract.
It has been hypothesized that potential effects of laser Nd: YAG laser posterior capsulotomy may affect macular pigment as well as choroidal thickness, macular thickness and anterior chamber parameters, so it was aimed to investigate possible effects of Nd: YAG laser posterior capsulotomy on macular pigment optical density, choroidal thickness, macular thickness and anterior chamber parameters in cases with posterior capsule opacification in this study.
The investigators would like to know if different imaging devices can improve the quality of images and visualization of imaged tissues. Also, the investigators would like to find out whether these changes are useful in the diagnosis and treatment of eye diseases. Using images of previous participants will allow us to demonstrate the advancement of different technologies, as well be used to allow comparisons between current technologies.
